FRIDAY - MARCH 21, 2003 - ISSUE NO. 58

Dear Friends and Industry Colleagues,

I hope this finds everyone in good health and good humor. I am really sorry that some readers got upset over the last issue. Some didn't like it because I put their name in the newsletter, and some didn't like it because I didn't. I guess if I didn't have anything to say all all, there would never be any controversy. My teacher in the seventh grade told us not to just sit there like oysters on the bottom of the ocean but to get out there and do something! Well, I am still doing things. They don't always turn out like I want them to, but I guess it is better to be unpopular than unknown.

This is my weekly newsletter about Wireless Data and Radio Paging. You are receiving this message because you have either communicated with me in the past about a wireless topic, or your address was included in another e-mail that I received on the same subject. This is not a SPAM. If you have received this message in error, or you are not interested in these topics, please click here, then click on “send” and you will be promptly removed from the mailing list. My apologies.

I heard that Ted Turner spoke to the CTIA Wireless Convention in New Orleans on Wednesday. He got some good laughs when he told about falling on hard times after he gave away most of his fortune. "It's pretty much gone now, I'm down to just over a billion now," he said. —Poor guy.

Paging industry shows ReFlex advances

March 17, 2003 1:00 AM EST

NEW ORLEANS—A group of the nation’s largest paging and messaging companies plan to meet today at the CTIA trade show to drum up support for the often-neglected industry.

"Despite rumors to the contrary, the paging industry has evolved and is meeting the demands of our customers that require reliable wireless messaging communications," said aid Doug Glen, chief operating officer of carrier WebLink Wireless. "For us, reliable messaging means an extensive network footprint, as well as great in-building penetration. Our subscribers also like that the monthly service charge for paging is the lowest of similar services."

WebLink joins Metrocall Inc., PalmSource Inc., PerComm and SkyTel Communications Inc. in a press conference today to show off a handful of new ReFLEX devices that will go on sale this year. On display will be four ReFLEX personal communication devices and three telemetry devices built by manufacturers including PerComm, Sun Telecom, Hunetec and Advantra. The companies are taking the place of ReFLEX developer Motorola Inc., which last year quit its role as the sole manufacturer of ReFLEX devices.

Gates Pitches Smartphone To Wireless Crowd

March 20, 2003

NEW ORLEANS—Comparing the current mobile computing environment to the early days of the PC, Microsoft Chairman Bill Gates took his company's campaign for becoming the dominant smartphone platform to the wireless industry.

Well, sort of. Gates delivered the keynote at what Microsoft is calling its first annual Mobility Developer Conference, which this year is being held at the same venue as the just-concluded CTIA Wireless 2003 conference.

Highlighting the importance Microsoft places on the wireless industry, the company offered complementary admission to Gates' address and to conference-related exhibits to those with badges to the CTIA show, which closed formally about a half hour before his speech late yesterday.

Gates noted the introductions this week at Wireless 2003 of two new smartphones running the Microsoft Smartphone platform: Samsung's SPH-i700 being offered by Verizon Wireless and Sprint, and the Hitachi g1000 offered by Sprint, using the Pocket PC platform.

And he encouraged developers to create applications for the Windows-based platform, stressing that for Microsoft, wireless will be a strategic sector for years to come. "Microsoft is at the very beginning of these businesses. We have a strong track record that we're going to invest," Gates told a full auditorium at the Ernest N. Morial Convention Center. "We are going to invest and invest and invest to get the most popular platform here, because we believe in these scenarios."

The scenario for mobile computing and communications is analogous to that in the 1990s, when software platform uniformity and the Internet spurred the development of waves of new applications, which helped fuel the decade's PC boom.

Now, although weighed down by weak economic and investment climates, the mobile sector is poised to take off because of a number of favorable factors such as the launch of advanced networks, the dropping price for handheld devices and widespread adoption of such devices by business and consumers.

TECH TIPS: DOWN-TILT ANTENNAS

Many paging sites were designed by old guys like me, but using "conventional wisdom" which, based on our two-way radio background, says: "put the antenna way-up high and use lots of power." We paging guys had to learn what the cellphone folks already knew: "put the antenna down where the customers are and use just enough power to get the job done."

If your site is already installed on a hill top, you can't follow the second idea. But all is not lost. You can set things right with a down-tilt antenna. Just remember that antennas are not amplifiers, they are passive devices, and even though they are rated in dBs of gain, they can only re-direct the signal or focus it in a certain direction. So, a 10 dB gain antenna just concentrates all the radiated energy straight out to the horizon. It takes it away from one direction and adds it to another. If you start out with 100 watts, you still have 100 watts even with a gain antenna. It's just focused like a spot light. It appears to be 10 dB stronger when you compare it to an antenna with no gain or when you check the signal off the beam. Whoever said that a 3 degree down-tilt antenna results in a 3 dB reduction in power, just doesn't understand the issue. Actually the proper down-tilt can increase the received signal level quite a bit in a given area. The trick is calculating the correct amount of down-tilt. My little drawing below may be helpful to you in doing this. You just need to draw a path profile, to scale, using a topographical map and the degrees of down-tilt required will become obvious. In many cases with a very high antenna, your signal is probably strong farther out, but not close in—maybe the area where you need it the most.

antenna radiation pattern drawing

The drawing above, shows the signal from a high gain antenna, on a mountain top, shooting out way over the top of a city, and the signal from a down-tilt antenna correctly radiating right at the city. There are some adjustable down-tilt antennas available, depending on the frequency band, which allow you to aim the pattern so the signal goes where you want it to be. I remember a mobile telephone system in Puerto Rico where the antenna was on a mountain just about like in this drawing. A few people in boats out in the ocean were getting good signals but the people on the land were not. The fix was to grab this vertical (omnidirectional) antenna and just physically bend the mast a little so that it tilted down. That solved the problem. Instead of sticking straight up like this: | the antenna was angled like this: /

Wiring for Wireless Sites

by Ira Wiesenfeld

ISBN 1-4018-1037-3

Price: $41.95

In the Author's Words. . ."It does not matter if you have one day or three decades of experience; you will find this book useful every time you enter a radio site. . . There are many books and training programs to explain how radios and electronics circuits work. Until this book, however, there was not an authoritative reference book to explain all of the intricacies involved with the planning and installation of wireless communication sites."

Wiring for Wireless Sites is one of only a handful of concise, yet highly technical information resources devoted exclusively to teaching readers the ins and outs of installing equipment in a wireless site.

A "go to" resource for site planning engineers and technicians, as well as professionals already in the radio and wireless installation and maintenance business, this book virtually eliminates hours of time linking generic electrical/electronic circuit theory to manufacturer-specific descriptions of cables before moving on to actual installation. Comprehensive coverage spans the spectrum, from equipment layout and wiring through grounding and lighting protection.

  • Safety precautions allow novices to develop sound and professional work practices as they gain new knowledge and hands-on skills
  • The importance of testing and documentation is emphasized, with specific procedures and guidelines included in nearly every chapter
  • Objectives, summaries and review questions focus attention on key points, allowing readers to gauge their understanding of key concepts and cabling techniques

About the Author

Can You Help?

newsstream As we all know, Wireless Messaging is less than 20 years old yet it is almost impossible to find evidence of our early experiments and successes.  Many of us experimented with wireless delivery of e-mail using the Teknow solution from the late 80s and others wrote simple scripts to parse and send SMTP messages to our pagers.  However how many of us documented these experiments?

Before what is left goes to the landfill, or is lost as us old timers start to die off, I would request help in archiving the following into a Museum of Early Messaging.  It appears that support to house this museum may be forthcoming from a pioneering company in Wireless Messaging but nothing is firm at this point.

  • Articles or papers on early 90s use of a browser on a two-way wireless device (Newton etc.)
  • Description of Anterior Technologies / RadioMail (pre Motorola) messaging Gateway and PDA/paging solutions.  Any magazine articles or early brochures on RadioMail would be very helpful.
  • Documentation and HP95LX software for the Motorola NewsStream module. Any articles on examples of uses would be great.
  • Any documentation magazine articles on the use of delivery of e-mail to a wireless device.
  • Back issues of Telocator Magazine from 1990-1995 time frame.
  • Motorola PCMCIA PagerCard with documentation and PC or PDA software.  Any articles depicting early use of the card also helpful.

If you think you can help with any of the above I am prepared to cover all hard costs as well as compensate fairly for any old hardware offered to the cause.  

Can you help? Give me a call or e-mail.

ON THE SOAP BOX AGAIN

To be politically correct these days we are not supposed to talk about religion or politics. I broke the first "rule" by sending out Christmas greetings to everyone last December. I guess the following personal political opinion will break the other one.

My uncle, Dean Hanks (1908-1944), was a Sergeant during World War II in the US Army, Company B, 25th Engineer Battalion, 6th Armored Division under the leadership of Lieutenant General George S. Patton Jr. He was killed on August 8, 1944, by a German machine gun sniper—while he was riding in a Jeep through a field near St. Lo, France. The Allied troops had landed on the Normandy Beaches on "D" day, June 6th, just a month before and were on their way to liberate Paris. The landing consisted of more than 150,000 men, a fleet of 5,000 ships and landing craft, 50,000 vehicles, and 11,000 planes. There were 4,900 Allied casualties the first day. By the time World War II ended over 50 million people had been killed.

hitler in paris
Adolf Hitler—Paris 1940

When I was very young, many nights I heard my mother crying about her older brother being killed. Many nights. . . It broke her heart.

He was buried in the St. James Temporary Cemetery in France and then his remains were later shipped home—in August of 1948. My grandmother insisted on having his casket opened in a back room at the funeral home so she could see him. She never spoke of him again. It broke her heart too. She was never the same after that.

He is now buried in the Phillips cemetery near Kinmundy, Illinois (USA). I visited his grave last September. He is there right next to my parents, grandparents, my brother, my aunts, uncles, great-grandparents, and great-great-grandparents. There is a plot for me there as well.

*According to the American Battle Monuments Commission there are 26,255 American dead from World War I buried in 4 cemeteries in France. There are 30,426 American dead from World War II buried in 6 cemeteries in France. These 56,681 brave American heroes died in their youth to liberate a country which is guilty of shameful behavior in the 21st century.

I think it is sad and very unfortunate that the French don't remember or appreciate the price that we Americans, the British, the Canadians, and people from many other countries paid to free their country. They would all be speaking German today if the free world had not joined together in their efforts to liberate them from German occupation. Maybe we should send the statue of Liberty back to them. It doesn't have the same meaning to us anymore.

Everyone is entitled to an opinion. This is mine.

UNTIL NEXT WEEK
