We know that vibrating pagers are a good way to alert people with hearing impairment. Now there are "bed shakers" to alert people who are sleeping. I guess this is an adaptation the device that some home theaters have in them to shake chairs and sofas during loud scenes in movies like explosions and falling rocks.

Sale of Motorola unit could have implications for handset division

November 12, 2009
10:36am ET
By Phil Goldstein


Several new organizations, led by a report in the Wall Street Journal, have said that Motorola is considering selling its Home and Networks Mobility unit for about $4.5 billion. The sale of the unit could have implications for the company's handset division, which it hopes to turn around by aggressively releasing smartphones based on Google's Android platform.

According to the reports, J.P. Morgan Chase & Co., Goldman Sachs and Centerview Partners are advising Motorola. The idea of selling the Home and Networks Division came about after two private-equity funds, TPG and Silver Lake Partners, approached Motorola and said they might be interested in buying the unit.

Motorola declined to comment on the sale of the unit, which makes set-top boxes and networking equipment, and accounted for about a third of the company's revenue in the third quarter. The company did say that it intends to continue with plans to spin off the handset division, which reported a 46 percent decline in year-over-year sales in the third quarter.

The timing of the news has perplexed analysts, especially given the continued weakness of Motorola's handset unit. "The mobile devices business still needs the rest of the businesses to fund its operations," RBC analyst Mark Sue told Reuters. "It hasn't really recovered fully yet so it would be a little too early to cut off the lifeline."

Indeed, Motorola is just beginning to ramp up its Android phone production. It has two Android phones on the market--the Droid from Verizon Wireless and the Cliq from T-Mobile USA--but plans to release at least 20 smartphones next year, most running on Android.

"The timing is surprising," Tero Kuittinen, an analyst at MKM Partners LP, told Bloomberg. "Most people would have expected the Motorola handset division to stabilize before the company made any major moves.

New Zetron P25 VoIP Systems
Improve National Park Communications

The National Park Service (NPS) recently installed Zetron’s VoIP Radio Dispatch Systems at two new NPS dispatch centers. The new P25 systems expand the coverage and effectiveness of park communications. They also prepare the centers to eventually provide regional dispatching.

Redmond, WA—October 30, 2009—The National Park Service (NPS) recently installed Zetron’s P25 VoIP Radio Dispatch System at two new NPS dispatch centers—one at the Midwest Regional Ozark Communication Center (MROCC) in Harrison, Arkansas, and the other at the Mount Rushmore National Memorial Dispatch Center, near Keystone, South Dakota. The new systems are P25 capable, support narrow banding, and improve coverage without requiring additional microwave and hard-wired connections. Tribalco of Bethesda, Maryland, served as the primary contractor for both projects.

"We can communicate even with our remote areas, and we’re better able to respond to emergencies," says Louie Stoops, lead dispatcher at the MROCC. "I also like the system’s simplicity and user friendliness. If we get busy and need to add dispatchers, they can learn the console very quickly." "Both systems are working flawlessly," says Joe Snyder, radio program manager for NPS, Midwest Region. "VoIP RDS not only meets our requirements for P25 and narrow banding, but it’s so flexible that it allows us to eventually offer 24/7 dispatching to parks that don’t have their own centers."

Missiles Go Mobile

Posted November 10th, 2009 by Harriet Rhodes in Mobile Phone News


A growing concern for any country is the threat of missile attacks, whether it’s part of a larger political war or as an act of terror. While the real concerns may not lie with the missile itself, more likely the aftermath and political repercussions, a key strategy for countries facing any such threat is evacuating people to safe areas away from the strike zone. Currently air raid sirens are used to identify and alert cities that are at risk of a rocket attack following a hostile launch. But these alerts are not always effective. Back in June Home Front Command conducted a five-day missile drill to help prepare Israelis and ensure everyone could get to a safe zone. According to a poll conducted by the Home Front Command, 46% to 60% of the general public drilled got to a safe zone when they heard the siren. Leaving almost half of the population in dangerous hot spots.

With this in mind, the Home Front Command has announced that within two years they hope to install a rocket alert system in Israel that will be able to calculate the precise location of an impact zone, and alert residents in affected neighborhoods via their mobile phones. Col. Dr. Chilik Soffer, head of the population department at the Home Front Command, said that advanced rocket sensors would soon be able to calculate the projectile’s exact landing site, “the rocket sensor will create a virtual ellipse and all the phones in that area will receive a warning”.

In a bid to increase the number of people that make it to the safe zones the alert will take four forms, mobile phone vibration, an audio alert, light flash or text message, “The more specific the alert, the more ready people will be” Soffer also stressed the importance of getting alerts to communities early. Around 90% of civilian casualties sustained in Israel during the second Lebanon war involved people who were struck by projectiles while they were in open areas, away from buildings. Civilians who seek cover in designated safe areas during rocket attacks are not likely to be wounded or killed.

If the Home Front Command can devise an advanced system, no doubt it will be rolled out worldwide. Despite the obvious positives, saving thousands of civilian lives there is the possibility that these alerts could be sent to warn the targets, therefore ruining any mission objective. Although if technology has advanced to receiving rocket impact estimations to a mobile phone one would assume it wont be too long until similar technology is made to counteract it.

Motorola May Return to ‘Apollo 11’ Roots If Unit Sold (Update1)

By Hugo Miller

sanjay jha Nov. 12 (Bloomberg) — Forty years after making the radio that Neil Armstrong used to speak the first words from the moon, Motorola Inc. may be considering a return to its roots, paring back the company to its most profitable unit.

Co-Chief Executive Officer Sanjay Jha said last month that Motorola, the biggest U.S. mobile-phone maker, is progressing with plans to spin off its handset unit. Now the company is exploring a sale of its home-entertainment division, which makes cable television set-top boxes, according to three people with knowledge of the plans.

Motorola lost more than $4 billion last year after its company’s phones failed to compete with Apple Inc.’s iPhone and Research In Motion Ltd.’s BlackBerry. Getting rid of phones and set-top boxes would leave Motorola as a maker of two-way radios and bar-code scanners, a business that proved more profitable over the past five years than the home-entertainment unit.

“The new Motorola in the long term will be grounded on its enterprise business,” said Ken Dulaney, an analyst at Gartner Inc. in San Jose, California. “The good thing is they have a degree of expertise in their enterprise business that’s not easy to replicate.”

A possible sale of the set-top box unit isn’t imminent, said two of the people, who declined to be identified because the discussions are confidential.

Surprising Timing

“The timing is surprising,” said Tero Kuittinen, an analyst at MKM Partners LP in Greenwich, Connecticut, who recommends selling the stock. “Most people would have expected the Motorola handset division to stabilize before the company made any major moves.”

Jennifer Erickson, a spokeswoman for Schaumburg, Illinois-based Motorola, declined to comment.

Motorola fell 8 cents to $8.69 at 9:45 a.m. in New York Stock Exchange composite trading. Before today, the shares had almost doubled this year.

Profit at the home-entertainment division fell 24 percent to $199 million in the third quarter, while sales dropped 15 percent to $2.01 billion. The unit accounted for about a third of revenue.

Motorola, or the Galvin Manufacturing Corp. as it was then known, introduced its first car radio in 1930 and two-way radio in 1940, according to the company’s history. A Motorola transponder aboard the Apollo 11 space capsule in 1969 relayed the astronauts’ words back to Earth from the moon.

The company sold the world’s first commercial mobile phone, the DynaTac, in 1984 and developed a hit with the Razr handset 20 years later. As the fortunes of the phone business languished in 2008, Motorola announced plans to split into two companies.

Cash-Flow Generator

Executives delayed the plans seven months later, citing the global financial crisis and slowing U.S. economy. In the mobile- phone market, Jha is counting on handsets based on Google Inc.’s Android operating system. Two phones, the Droid and the Cliq, went on sale this month.

Private-equity firms are among potential bidders for the home and networks mobility business, the people said. A price tag of about $4.5 billion, reported yesterday by the Wall Street Journal, “makes sense,” said Matt Thornton, an analyst at Avian Securities LLC in Boston, who rates Motorola “positive” and doesn't own the shares. That price would represent an 18 percent premium over his $3.8 billion valuation, Thornton said.

“The home networks business isn’t a growth business,” Thornton said. “What it can be is a cash-flow generator. It doesn't require investments.”

Private-equity firms including TPG and Silver Lake may be interested in the business, the Journal reported, citing people familiar with the discussions. Owen Blicksilver, a TPG spokesman in Fort Worth, Texas, declined to comment. Calls to Menlo Park, California-based Silver Lake weren't returned.

The company retained JPMorgan Chase & Co. and Goldman Sachs Group Inc. as advisers on a possible sale, the Journal said, citing people familiar with the matter. Andrea Rachman, a spokeswoman for Goldman Sachs, declined to comment, as did Tasha Pelio, a spokeswoman at JPMorgan.

Want to bone up on wireless tech? Try ham radio

Abundant spectrum resources and an engaged research community are drawing wireless experimenters back into a hobby that many had forgotten.

By John Edwards
October 29, 2009 06:00 AM ET

John D. Hays, an IT manager in Edmonds, Wash., devotes most of his spare time these days to helping develop a communications system that's designed to integrate portable two-way radios with the global telephone network. The project's goal is to create a failure-proof voice communications infrastructure that can immediately connect first responders with the outside world.

"Individuals with radios in the field could interconnect with the telephone system even when their cell phones are shut down by an emergency," he says. This would be useful in all manner of disasters, from natural to man-made.

Hays claims his research efforts wouldn't be possible if he wasn't a licensed amateur radio operator — or "ham," the term he and his fellow hobbyists use to describe themselves. He says ham radio gives him "space and a choice of spectrum [in which] to experiment." He also values the hobby's largely self-policing regulatory structure and close-knit user community. "There are many others who would share your passion and provide [a] great opportunity for brainstorming and support," says Hays, whose ham call sign is K7VE.

For IT professionals, ham radio can foster skills that are translatable into real-world wireless and wired networking applications.

Hays says his hobby and profession have long been intertwined. His experimentation with TCP/IP over AX.25 (a ham-oriented data link layer protocol) on the radio in the late '70s and '80s "helped me understand the inner workings of networking protocols and the use of wireless transports," he says. "From this, I was able to write some widely read and popular internal papers on subjects such as TCP/IP over Ethernet verses token passing ring topology."

  • Number of U.S. amateur radio licensees: 650,000
  • Number first licensed in the past four years: 100,000
  • Number estimated to be licensed in 2009: 25,000 to 30,000

Source: American Radio Relay League, Newington, Conn.

More recently, Hays used his ham knowledge to implement several RF-networked warehouse management systems. "My knowledge of radio transmission, combined with networking [skills], optimized the placement of base stations and mobile units," he says.

Reviving innovation
Decades ago, amateur radio operators were on the forefront of scores of technological innovations, including television, digital communications, solid-state design and cellular networks. The hobby's roots trace back to radio pioneers such as Guglielmo Marconi and FM-inventor Edwin Armstrong.

But in recent years, as many potential new hams were attracted to computers, the Internet and other technologies that they could explore without passing a licensing exam, some veteran hams worried that ham radio was at risk of gradually sliding into stagnation and was perhaps even on the road toward technological irrelevance. Over time, many old-timers worried, experimenters would gradually be replaced by hams more focused on the hobby's operational aspects, such as restoring antique radios and providing communications services for community parades and other charity events.

Other hams, however, believed that the hobby was actually entering a new era of innovation, one driven by the same type of people lured away from ham radio by advancing digital technologies. They reasoned that a streamlined licensing system, capped by the FCC's elimination of Morse code testing two years ago, would, over time, revitalize the hobby. This would happen by attracting technically skilled innovators who were interested in more than merely tapping a telegraph key.

Whatever the reason, a budding corps of innovators is now working to restore at least some of ham radio's past glory, focusing on projects ranging from satellite construction to power-line communications to testing long-range Wi-Fi links. "Ham radio provides the broadest and most powerful wireless communications capability available to any private citizen anywhere in the world," says Allen Pitts, a spokesman for the American Radio Relay League (ARRL), a national association of ham radio operators based in Newington, Conn.

Major pluses: Free radio spectrum, big transmitters and more

Amateur radio license classes

A look at the exams ham radio enthusiasts must pass to earn the following licenses:

  • Technician: 35-question multiple-choice exam for full operating privileges on all ham bands above 30 MHz and limited privileges in portions of HF amateur bands.
  • General: 35-question multiple-choice exam for privileges on all ham bands above 30 MHz and most HF amateur frequencies.
  • Amateur Extra: 50-question multiple-choice exam for all ham operating privileges.

For experimenters, ham radio's strongest drawing card is megahertz upon megahertz of lightly used (sometimes virtually unused) radio spectrum at key locations in the LF, HF, VHF, UHF and SHF bands and beyond. Unlike their commercial counterparts, hams are free to use any of these frequencies for experimental purposes without any government authorization other than the ham license itself. "Don't underestimate the value of these frequencies — they could fetch hundreds of millions of dollars if sold," says Hays, who views the bands as a "national resource," useful for both experimental and disaster-related communications activities.

Beyond gaining access to enough radio spectrum space to conduct their experiments in relative peace and privacy, hams can also legally use transmitters with power levels of up to 1.5 kilowatts. "That's comparable to a small AM broadcast station," Pitts says. A high-power transmitter comes in handy for applications like bouncing a radio signal off of Venus (as a group of German hams did earlier this year) or for skipping signals off of the ionosphere to communicate with someone on the other side or the world without the help of the Internet.

Technician exam sample question

What is meant by receiver front-end overload?

  • A. Too much voltage from the power supply
  • B. Too much current from the power supply
  • C. Interference caused by strong signals from a nearby source
  • D. Interference caused by turning the volume up too high

Correct answer: C

Although radio amateurs have long battled local governments and homeowners' associations over the right to erect antennas in their yards, a recent FCC ruling now requires planning authorities to "reasonably accommodate" a ham's need to erect the large antennas that are useful for satellite communications, radio astronomy and other types of weak-signal radio applications, as well as long-distance terrestrial communications.

Testing, testing
Yet aspiring hams still face the challenge of passing one or more written tests, depending on the class of license they are seeking. Those exams cover both technical and regulatory subjects. The entry-level Technician-class license, which provides access to nearly all VHF and higher frequencies, requires applicants to pass a 35-question, multiple-choice test. "While not difficult, it does require several hours of reading and study," Pitts says. "This initial test is designed to be sure that new licensees understand the service, can operate competently without causing disruption to others, and have a basic knowledge of the rules and capabilities of ham radio."

Two higher-level licenses — General and Amateur Extra — require applicants to demonstrate progressively greater knowledge and understanding of technical and regulatory issues in exchange for access to more frequencies.

The downside to using ham frequencies for wireless experimentation include an FCC rule prohibiting encryption that hides the meaning of a transmission, bandwidth limits on some modes and frequencies, and the hobby's strictly noncommercial nature. "No pecuniary benefit can arise out of communication you are engaged [in] on the air," says Hays, who believes that the advantages far outweigh the drawbacks.

Skill building
Experimenters are using ham radio as a way to pioneer an array of new technologies as well as to refine many existing products and services. One popular activity, Pitts says, is testing Wi-Fi's distance boundaries. "A number of consumer-grade wireless network routers share frequencies with amateur radio," he says. "With an amateur radio license, you can legally couple amplifiers to these routers and, with gain antennas, extend their range to cover several miles or more." Pitts notes that hams have used these techniques to create experimental high-speed wireless networks that encompass entire cities.

Meanwhile, at the U.S. Naval Academy, midshipmen hams are in the process of sending a series of small communications satellites into orbit with the help of NASA. The project's goal is to develop a low-cost orbital platform for flying various types of scientific instruments into space.

General exam sample question

What signal(s) would be found at the output of a properly adjusted balanced modulator?

  • A. Both upper and lower sidebands
  • B. Either upper or lower sideband, but not both
  • C. Both upper and lower sidebands and the carrier
  • D. The modulating signal and the un-modulated carrier

Correct answer: A

Richard Campbell, an associate professor of computer and electrical engineering at Portland State University in Oregon, says ham radio helps him turn theoretical concepts into reality. Campbell, licensed as KK7B, is currently working on projects that are designed to add digital communications capabilities to the national power grid and to create remote sensors for use with ocean wave power generators. "Amateur radio serves as the testbed for new ideas I like to play around with before looking for commercial applications," he says. "Much of what I am experimenting with at the moment will likely end up in low-power wireless networks, such as the smart grid."

Over the years, many hams have parlayed their radio experimentation into lucrative and even distinguished professional careers. Joe Taylor, licensed as K1JT, says the years he spent tinkering with radios led him into his current post as a Princeton University physics professor. "My practical knowledge of RF techniques, built up over years of enthusiastic pursuit of many amateur radio goals, turned out to be very useful when choosing and designing specialized equipment for unique studies of pulsars and other astrophysical objects," he says. In 1993, Taylor was awarded the Nobel Prize in Physics for the co-discovery of a new type of pulsar.

No formal training needed
As it has since its earliest days, the hobby also continues to attract experimenters without any formal electronics training. Many of these people "homebrew" their own radios and accessories, building equipment from components obtained commercially, collected through purchases or trades with fellow homebrewers or even painstakingly crafted by hand.

Bill Meara, a diplomat stationed at the U.S. embassy in Rome, experiments with bare-bones radio technologies. "I am tinkering with one of the simplest possible high-frequency radio transceivers — it uses just one transistor," he says. The single sliver of silicon serves as both a transmitter and receiver. "In an age in which we use chips with millions of transistors inside, I kind of like the idea of going minimalist," he says.

Meara, who hosts SolderSmoke, a podcast targeted at electronics hobbyists, recently wrote a book on his life as a radio experimenter. He feels that ham radio gives amateur researchers like himself easy access to professional-level support resources, ranging from technical discussion groups to international meetings.

Extra exam sample question

What is the purpose of Q1 in the circuit shown in the figure below?

  • A. It provides negative feed back to improve regulation
  • B. It Provides a constant load for the voltage source
  • C. It increases the current-handling capability of the regulator
  • D. It provides D1 with current


(Correct answer: C)

On the flip side, the hobby provides science and engineering professionals with an opportunity to test ideas in a low-key environment. "It offers [them] the chance to legally play with some of the most cutting-edge technologies available today... without any of the pressure that may come with professional, on-the-job experimentation," Meara says.

Looking ahead
Amateur radio isn't likely to ever recapture the grip it held on the technology industry from the 1950s through the 1970s, when it seemed that virtually everyone in electronics design and the technical end of radio held a ham license. For his part, Campbell feels that even a modest return to ham radio's experimental roots would be a good thing. "We just celebrated the 40th anniversary of Apollo 11; maybe the past isn't such a bad place to think about."

Meara believes that radio experimenters need to take a second look at ham radio and consider the changes it's undergoing. "Some of the most important discoveries in radio came from ham radio home laboratories," he says. "There is no reason this tradition can't be continued into our new age of wireless."

Having ridden to election in part on the back of the previous administration’s lack of readiness for and response to natural disaster, the Obama administration and Democratic Congress seem willing, if not eager, to commit the same egregious errors of their own.

The following story constitutes an editorial opinion, based on current facts, by GPS World editor Alan Cameron. Response mechanism included.

In 2001, the U.S. Department of Transportation’s Volpe Report clearly indicated the vulnerability of GPS to interference, both intentional and unintentional, as well as disruption due to natural atmospheric factors. It also delineated the consequent vulnerability of critical national infrastructure of several kinds, which depend upon GPS for highly precise timing, as well as position and navigation. Since that date, not a single administration finger, red or blue, has lifted in proactive response. Minimal hand-waving has occurred. Now the executive fist, seeking to wring some drop of financial savings from some obscure program somewhere, has clamped on Loran, the sole practical back-up to GPS, and throttled the life out of it.

This in blithe ignorance of the government’s own commissioned Independent Assessment Team, which found that “the cost of deploying eLoran technology [an updated improvement on Loran] would be about $100 million, which is about the same cost as dismantling the current Loran infrastructure.” The philosophy, if Congress and government are even aware of the thought underpinnings of their actions, seems to be “You’ve got to spend money to save some,” bearing an eerie resemblance to a previous era’s operational dictum, “In order to save the village, we had to destroy it.” It further portends ill for the overall national infrastructure that the President has claimed he intends to restore, strengthen, and solidify.

On October 28, President Barack Obama signed into law a bill that effectively terminates the struggle to mount back-up system for GPS: Loran-C and eLoran, a system that could prevent national and industrial infrastructure breakdown in the event of various probable disruptions, interference, or intentional jamming.

The President signed the Department of Homeland Defense (DHS) appropriations bill that allows termination of Loran-C in Jan 2010. The U.S. House of Representatives also passed a revised version of its Coast Guard authorization bill, replacing the mandate to convert Loran-C into eLoran with a call for its termination, in line with the DHS appropriations bill. Further details are available at the PNT website.

The Coast Guard Commandant and DHS are expected to sign off almost immediately that Loran-C can be terminated. Once they sign it, Loran signals could go off the air as soon as January 4, 2010.

In his first budget, President Obama stated that Loran-C was obsolete, and that obsolete systems would be eliminated. The administration and Democrat-led Congress continue to assert, in the face of expert testimony and evidence to the contrary, that Loran-C is the poster child of obsolete systems, and must be killed. The politicians appear immune to any notion that GPS is vulnerable to a range of disruptions, and that the national timing, communications, and financial infrastructures that depend on GPS are likewise open both to intentional attack and to natural interference.

The attached PDF reproduces in its entirety a letter to Secretary of Homeland Defense Janet Napolitano from Senators Joseph Lieberman (chair, Senate Committee on Homeland Security and Governmental Affairs) and Senator Susan Collins, ranking member of same committee. The following paragraphs briefly excerpt key portions of the letter.

“It is vital that you have the input of critical infrastructure users of GPS before deciding on this certification [that Loran-C is not needed as a back-up to GPS], and the Department’s survey of these users has not been completed.”

“In January 2009, an Independent Assessment Team, commissioned jointly by DHA and DoT, released a report that unanimously concluded that eLoran should serve as the national back-up for GPS and that the Loran-C infrastructure should be maintained until full eLoran deployment.”

[Editor’s note: The IAT report was actually completed in 2007, but withheld from public release by the U.S. government for two years, until various filings forced it into the open.]

“Aside from signal interference an limitations related to depletion of the GPS constellation, there is also the danger of intentional actions to destroy,or jam the signal of, GPS satellites.”

“DHS officials committed during their confirmation hearings that the Department would provide [its survey of all 18 critical infrastructure sectors to determine whether a backup to GPS is needed] by July 30, 2009. Three months after its due date, that survey has not been completed. Any decision to certify the decommissioning of Loran infrastructure should be delayed until this report is provided to and reviewed by Congress.”

George E. Smith, AA2EJ, Wins Nobel Prize

Nobel Laureate George Smith, AA2EJ. Smith received the 2009 Nobel Prize in Physics for his invention of the charged-couple device (CCD).



This very first CCD prototype was pieced together months after Smith and Boyle laid out its working principles.



Today, a smaller CCD that the one first envisioned 40 years ago can hold much more information.



The original notes from the Smith and Boyle’s brainstorm meeting on September 8, 1969 — the date that they made the first sketch of a CCD.



Without CCDs, this image — taken by the Hubble Space Telescope in 2002 showing "light echos" illuminating the dust around super-giant star V838 Monocerotis (V838 Mon) — would not be possible. V838 Mon is located 20,000 light-years away on the periphery of our Galaxy. In early 2002, it increased in brightness temporarily to become 600,000 times brighter than our Sun. The reason for the eruption is still unclear.

Around 5:30 on the morning of October 6, George E. Smith, AA2EJ, of Barnegat, New Jersey, got a phone call that changed his life: He had just found out he had won the Nobel Prize in Physics for 2009 "for the invention of an imaging semiconductor circuit — the CCD sensor." Smith will share the prize money with two other recipients: Charles K. Kao, of Standard Telecommunication Laboratories in the United Kingdom and Chinese University of Hong Kong in Hong Kong, China, and Willard S. Boyle, of Bell Laboratories. Each recipient will receive a diploma, a medal and a document confirming their share of SEK 10 million (about 1.4 million US dollars); Kao will receive 50 percent, while Smith and Boyle will each receive 25 percent of the monetary award.

Kao was recognized by the prize committee for his "groundbreaking achievements concerning the transmission of light in fibers for optical communication." His discoveries paved the way for optical fiber technology, used for almost all telephony and data communication today. Boyle and Smith invented a digital image sensor — the CCD — that has become an electronic eye in almost all areas of photography.

"Amateur Radio has always attracted individuals who want to understand and exploit nature's laws," fellow Nobel Laureate Joe Taylor, K1JT, told the ARRL. "These are essential characteristics for first-rate scientists, as well. The 2009 Nobel Prize in Physics honors the invention of an imaging semiconductor circuit — the CCD sensor used in digital cameras, the Hubble Space Telescope and many other scientific and consumer devices. It was no great surprise to learn that one of the Laureates, George Smith, is also a radio amateur." Taylor was awarded the Nobel Prize in Physics in 1993 "for the discovery of a new type of pulsar, a discovery that has opened up new possibilities for the study of gravitation."

Smith earned his PhD from the University of Chicago in 1959 with a dissertation of only three pages, which he later described as "short, but pretty good." Like Boyle, Smith was a serious sailor and the two took many sailing trips together. After his retirement, Smith sailed around the world for 17 years, according to an interview he gave to the Adam Smith, Editor-in-Chief of the Nobel Foundation's official Web site; he only gave up sailing in 2001 to spare his "creaky bones" from further storms.

"As you know, we sailed around the world for 17 years," Smith told the ARRL. "While we were on our boat, we used Amateur Radio, especially in the South Pacific. My wife Janet, AA2EI, was the principal radio operator. With our radio, we could keep track of other boats in the area. Over in the Southwest Pacific, there are shore stations that provide weather forecasts every day on the ham radio. We would listen for these, as it was such a tremendous help for us as sailors. Janet and I haven't really been on the radio since we got back to the US in 2003. The boat's out stuck behind our house; we have a dock back there."

The CCD — invented in about an hour over lunch when Smith and Boyle worked together at New Jersey's Bell Labs — was, according to Wired Magazine, the first practical way to let a light-sensitive silicon chip store an image and then digitize it. In short, it is the basis of today's digital camera.

According to Wired, the "most amazing thing about the invention" is that Boyle and Smith came up with the design so quickly. With Bell Labs threatening to take the funds from their department and transfer the money to other research, Boyle had to come up with a competing semiconductor design. He got together with Smith, and within an hour, they came up with the idea and sketched it all out on a blackboard.

"One morning in October, 1969," Boyle wrote on his Web site, "I was challenged to create a new kind of computer memory. That afternoon, I got together with George Smith and brainstormed for an hour or so on a new kind of semiconductor device, drawing a few sketches and equations on a blackboard. We called it a charge-coupled device: A 'CCD.' When we had the shops at Bell Labs make up the device, it worked exactly as expected, much to the surprise of our colleagues."

For their invention of the CCD, Smith and Boyle have also jointly received the Franklin Institute's Stuart Ballantine Medal in 1973, the 1974 IEEE Morris N. Liebmann Memorial Award and the 2006 Charles Stark Draper Prize.

When asked by the ARRL how he felt about winning the Nobel Prize, he exclaimed, "I feel great! Even though there's a lot of nonsense to go through with it, it's worth it and winning it does wonders for your ego. Aside from the initial shock and having to go through piles of mail, e-mail and returning telephone calls, I know that will calm down. As for the long-range future, I'm getting many invitations to give talks. Next year, I've been invited to speak at a major conference in Seoul, South Korea, another in Portland, Oregon and another in Switzerland. I've been invited to France to give a talk, China, too. We need to sit down with a calendar and figure it all out. Having a Nobel makes a big dent in your lifestyle."

Smith told the ARRL that he knew the CCD was under consideration for the Nobel Prize, "but we didn't know exactly if, or when, it would happen. Research that wins the Nobel is often done many years beforehand. In my case, this was 40 year old research. The Prize Committee wants to make sure the research has stood the test of time.

Next month, Smith will travel to Stockholm, Sweden for the award ceremony on December 10. It is certain that his picture will be taken scores of times by the international media, made possible through the technology that he and Boyle pioneered.

What Is a CCD?

In most solid-state applications, a CCD translates light into an electronic signal. The sensor is made up of pixels, each of which is a metal-oxide semiconductor (MOS) capacitor. As the light falls on each pixel, the photons become electrons due to the photoelectric effect, the same thing that produces solar power. The photoelectric effect happens when photons of light hit the silicon of the pixel and knock electrons out of place. On a CCD, these electrons are stored in a "bucket": the pixel's capacitor.

At this stage, the "image" is still in analog form, with the charge — or amount of electron in the bucket — on each pixel directly corresponding to the amount of light that has hit it. The genius of Boyle and Smith's CCD was the reading of the information stored. Essentially, the charge in each row is moved from one site to the next, a step at a time. This has been likened to a "bucket row" or human chain, passing buckets of water down a line. As these buckets of electrons reach the end of the line they are dumped out and measured. This analog measurement is then turned into a digital value. Thus, a digital grid is made that describes the image. That signal can be digitized and transformed by the dull magic of high-performance computing into images from the Hubble Space Telescope (HST).

The image from a CCD, such as the ones on the HST, is black and white. For television and photographic media, placing a red, green or blue colored filter over the top of each pixel allows color information to be read directly from each pixel — but only for one primary color per pixel. Subsequently, software can also extrapolate the color of adjacent pixels based on their brightness so that each pixel winds up with its own red, green and blue values.

CCDs: Not Just for Your Digital Camera

The advantages of the electronic image sensor quickly became evident. In 1970, just about a year after the invention, Smith and Boyle could demonstrate a CCD in their video camera for the first time. In 1972, an American company constructed the first image sensor with 100×100 pixels and entered production a few years later. In 1975, Boyle and Smith themselves constructed a digital video camera of a sufficiently high resolution to manage television broadcasts. It would not be until 1981 before the first camera with built-in CCD appeared on the market. Its bulky and primitive characteristics when compared to contemporary cameras initiated a more commercially oriented digitalization in the field of photography. Five years later in 1986, the first 1.4 megapixel image sensor (1.4 million pixels) arrived. Nine years later in 1995, the world's first fully digital photographic camera appeared. Camera manufacturers around the world quickly caught on, and soon the market was flooded with ever smaller and cheaper products.

No one initially predicted that the CCD would become indispensable to the field of astronomy. But it is precisely thanks to digital technology that the wide-angle camera on the HST can send the most astonishing images back to Earth. The camera's sensor initially consisted of only 0.64 megapixels 800×800 pixels); however, as four sensors were interconnected, they provided a total of 2.56 megapixels. This was a big thing in the 1980s when the Hubble was designed. Today, the Kepler satellite has been equipped with a mosaic sensor of 95 megapixels, and the hope is that it will discover Earth-like planets around stars other than the Sun.

Early on, astronomers realized the advantages of the digital image sensor. It spans the entire light spectrum, from X-ray to infrared. It is a thousand times more sensitive than photographic film. Out of 100 incoming light particles, a CCD catches up to 90, whereas a photographic plate or the human eye will only catch one. In a few seconds, light from distant objects is gathered — a process that previously would have taken several hours. The effect is also directly proportional to the intensity of the light — the larger the amount of light, the higher the number of electrons.

For the really dim things astronomers look at, the number of photons of light coming from a source is so small that each one counts. Out of every 100 photons, a CCD can record more than 90 of them. Photographic plates can barely reach 10 percent. And your eyes? Their quantum efficiency is in the 1-4 percent range.

In 1974 the first image sensor had already been used to take photographs of the moon — the first astronomical images ever to be taken with a digital camera. With lightning speed, astronomers adopted this new technology; in 1979 a digital camera with a resolution of 320×512 pixels was mounted on 2.1 meter telescope at Kitt Peak National Observatory (KPNO), just outside Tucson, Arizona.

Today, whenever photo, video or television is used, digital image sensors are usually involved in the process. They are useful for surveillance purposes both on Earth and in space. CCD technology is also used in a host of medical applications, such as imaging the inside of the human body — both for diagnostics and for surgical operations. The digital image sensor has become a widely used instrument at the service of science both at the bottom of the oceans and in space. It can reveal fine details in very distant and in extremely small objects. In this way, technological and scientific breakthroughs intertwine.

Smith and Taylor are not the only radio amateurs to receive the Nobel Prize in Physics. Sir Martin Ryle, FRS, G3CY (SK) shared the 1974 Nobel in Physics with Anthony Hewish "for their pioneering research in radio astrophysics." Ryle received his for inventing the aperture-synthesis technique for radio astronomy (interferometry); Hewish received his for his decisive role in the discovery of pulsars. Guglielmo Marconi — who always considered himself an "amateur" — shared the 1909 Physics prize with Karl Ferdinand Braun "in recognition of their contributions to the development of wireless telegraphy." This, at a time when there were no licenses and only amateurs. — Thanks to Wired Magazine and the Nobel Foundation for information.

What might have been

The Nortel team that designed it more than a decade ago says their machine could have become a combination BlackBerry/iPhone, if a lot of things had gone right. They did not.

Originally published Jul 21 2007

Thirteen years ago — an eon in high-tech terms — a small group of psychologists, industrial designers and engineers invented the future at Nortel. The result can be seen today in a stunning 18-inch by 24-inch photo that hangs on the home office wall of John Tyson, the man who ran Nortel's Corporate Design Group for many years.

The image is a highly stylized, eerie evocation of Apple's more recent ads. Inside the frame, a female model holds a working prototype of a phone that slides out to produce a full keyboard and a large screen. Touching different parts of the device with a stylus or finger transforms the device into a pager, voice mailbox, wireless phone or fax machine.

The device was called Orbitor and had Nortel played things differently, it could have engineered a brilliant exit from the great telecom crash of 2001.

Instead, a pair of high-tech icons — California-based Apple and Research in Motion of Waterloo, Ont. — exploited the opportunities that Nortel and so many others missed.

They are now establishing just how valuable the franchises are. Paced by sales of the iPod (music downloads) and the iPhone (wireless Internet phone), Apple has seen its market value surge nearly 160 per cent from a year ago to $121 billion (all figures U.S.) At the same time, RIM is riding a surge in popularity for its BlackBerry devices — which make possible e-mail on the go. The company's share price has soared 264 per cent from a year ago, giving it a market capitalization of almost $44 billion.

In sharp contrast, Nortel's one-year return has been a relatively pedestrian 18 per cent, for a market value of $11 billion.

The question of how Nortel missed the mark fascinates because there is no doubt among the Orbitor's designers that they had the smarts to beat Apple in particular to the iPhone.

"Yes, absolutely!" Mr. Tyson said in response to a query about whether Nortel could have managed the trick. Certainly the technical and design talent was there.

Consider, for instance, the experience of Don Lindsay who developed the Orbitor's user interface — the combination of software and design that makes the device easy to use.

Mr. Lindsay, a protege of Mr. Tyson, left Nortel in 1994 to join Apple. There, he hired the team that created the Macintosh computer's OS X operating system. Although Mr. Lindsay now works at Microsoft, where he run a design group at Microsoft Live Labs, his influence at Apple would remain profound. His OS X team created the user interface for the iPhone.

Of course, the same group might not have produced a similar product within Nortel, where the R&D culture revolves around the heavy-duty technology that lies at the core of large communications networks.

However, Ken Blakeslee, the former vice-president of business development who led the Orbitor project, recently shed light on just how close Nortel came to selling the Orbitor concept to one of Europe's biggest cellular phone operators.

"We had 80 finished units going into market and service delivery trials with CellNet (now O2 Telefonica) in 1998," noted Mr. Blakesee, who advises wireless carriers through his British-based consulting firm WebMobility Ventures.

"We were so close to bringing (Orbitor) to life," he said.

What happened? The short answer is that Nortel's top brass briefly considered the enormous risks involved and took a pass.

A host of factors went into this decision, not least of which was the company's relative inexperience with wireless technology and consumer electronics. Nortel acquired much of the wireless know-how for Orbitor through its 1992 purchase of a stake in France-based Matra. But this investment was aimed more at acquiring the wireless technology that drives GSM-standard networks — and not the consumer-style electronics typical of mobile handsets that link to the networks.

"We simply could not design and manufacture cost competitive (handsets)," former CEO John Roth noted this week in response an e-mail. "Nortel's circuit design skills were in large systems and not in consumer products." The wireless services industry was also in a state of flux in the late 1990s. There were three prevailing technical standards for wireless networks (TDMA, GSM and CDMA) and the industry was moving rapidly to third-generation systems that offered higher speeds.

Finland-based Nokia and Chicago-based Motorola were generally considered the favorites to win in the transition. Nokia has a superlative logistics system, along with the ability to design attractive, low-cost handsets. Motorola at the time had the advantage of manufacturing its own semiconductors, which also contributed to lower cost phones.

Mr. Tyson noted that Nortel faced an additional problem. Its engineers at the time were used to designing products that had a life expectancy of five years or more. With Orbitor, they would have to create fresh models every 18 months — even faster later on. This would demand another level of productivity from the designers.

Even so, the decision to build the initial Orbitor prototype was fairly easy.

"You can do wonders with temporary tools to create prototypes for customer trials," said Mr. Tyson. "The key, though, is to commit tens of millions of dollars to go to high-volume manufacturing." The Orbitor group was forced to fight other units within Nortel for these kinds of resources.

And it lost.

It had taken nearly four years to move from concept to customer trials early in 1998. Then followed a period of hiatus as Nortel considered whether to move to the next stage and begin high-volume manufacturing.

Finally, in 2001, as the telecom crash got underway, Nortel killed the entire 120-strong Corporate Design Group — the unit that concerned itself with ergonomics and designs that appealed to the eye and hand (as distinct from Nortel's thousands of electronic engineers and network design specialists).

For senior Nortel managers, killing the group was an easy call. The company was losing buckets of money and the group was not contributing to the revenues. It was a matter of survival. Mr. Tyson, who had retired in 2000, believes it was a false economy.

"They really underestimated the value of the unit," he said.

The reason: The Group came as close to anything else within Nortel to replicating the freewheeling design culture at Apple — perhaps because Mr. Tyson's charges spent their days tweaking devices used by consumers, not telephone engineers.

No doubt, Nortel's executives saw in Nokia's dominance in the field of wireless handsets confirmation of their decision not to back Orbitor.

Yet, that's only part of the story. Nokia, after all, simply stuck to its strengths. There was plenty of room, it turned out, in a couple of very lucrative new niches.

Had Nortel committed to Orbitor, there's no telling what direction the design effort might have gone. Nortel, an early pioneer in the use of e-mail in its internal communications, could have challenged Research in Motion. And Mr. Roth's company certainly had enough time to produce an iPhone to rival that of Apple.

In fact, it's worth examining the state of RIM and Apple in 2001, the year Nortel killed its Corporate Design Group, along with Orbitor.

RIM, for instance, had very little heft in 2001 when it posted sales of just $221 million — while Nortel the same year recorded a lofty $17.5 billion in revenues.

RIM was completely focused on wireless data technology, and growing swiftly. Nevertheless, it remained vulnerable. Company prospects stalled in fiscal 2003 and RIM co-CEOs Mike Lazaridis and Jim Balsillie would spend the next few years persuading the planet's biggest carriers to equip themselves with BlackBerry servers. This is what laid the groundwork for RIM's recent explosion in new sales.

At Apple, the prospects actually looked bleak in 2001. Company revenues had sunk to $5.4 billion — the lowest since the late 1980s and only half the level of 1995. But 2001 also marked the debut of the iPod. This is the music carrying device that last year for the first time accounted for more revenues at Apple than the sale of computers.

Apple co-founder Steve Jobs followed this coup last month with the introduction of the iPhone, further pushing the company into the realm of consumer electronics.

It is far from clear that the iPhone will be a commercial success. The design is undeniably beautiful but it works so far only on AT&T's network. But that's the thing about Apple — you can be sure its technocrats are resolving the issue of coverage even as the firm's overactive design group is coming up with fresh models.

Apple saw an opportunity and went for it, fully confident in the ability of its designers to measure up.

When Nortel closed Mr. Tyson's design group in 2001, it stuck to what it knew best — the complex networks that allow the BlackBerry and iPhone to function. Nortel has been a player in the industry long enough to appreciate this may yet prove to be the right call. It's just difficult to believe amid the noise generated by a pair of firms that were mere pipsqueaks when Nortel got out of their way.

EWA and Space Data Agreement
Provides Streamlined
Access to National Block of Spectrum

(Mclean, VA) Enterprise Wireless Alliance (EWA) announced an agreement with Space Data to make approximately 2 MHz of 900 MHz nationwide NPCS spectrum available to members and customers. This unencumbered, clean spectrum is suitable for flexible use including Machine to Machine (M2M) and digital technologies for voice, Push to Talk (PTT) or broadband and video and can be leased or purchased through EWA.

"EWA routinely responds to spectrum availability requests from manufacturers, wireless sales and service providers and large enterprise users of radio spectrum", explained Mark E. Crosby, President and CEO of EWA. "EWA brings expertise in creating a database for the Space Data spectrum and valuable spectrum management services including automated frequency coordination. This Space Data spectrum will be of great interest and a valuable asset to EWA members and customers."

"EWA's well earned reputation for spectrum expertise, from identifying frequency availability to ensuring best and highest use, is among the reasons we created this partnership," according to Jerry Knoblach, Chairman and CEO, Space Data. "We are enthusiastic about EWA's national presence, unique expertise and broad access to potential customers."

Space Data is the largest holder of NPCS 900 MHz spectrum licenses in the US. The leader in near space communications, Space Data's SkySite®, platforms provide wide area coverage from altitudes of 65,000 to 100,000 feet. SkySites provide coverage footprints of over 400 miles in diameter (over 125,000 square miles per site) in areas where traditional terrestrial based networks are not available or practical and satellite services are cost prohibitive. Space Data's near space technology is routinely used in military applications to extend the range of tactical communications. Space Data offers digital PTT, data and interconnect services utilizing iDEN technology to enterprise users through its switch facilities on customer held or Space Data spectrum. Additional information is available at

EWA is an FCC-certified frequency advisory committee that provides license preparation, spectrum management and associated services to business enterprises, public safety entities and wireless sales and service organizations. Membership within EWA is open to users of wireless communications systems, manufacturers, system operators and service organizations. EWA publishes its e-newsletter Insider, provides regulatory updates, publishes Enterprise Wireless magazine, offers the Enterprise Wireless Solutions Center and convenes an annual conference with a technology showcase for new wireless products and business operations sessions. The 2009 conference was held November 4-6 at the Westin Buckhead, Atlanta, Georgia. Additional information about membership and services is available at
