FRIDAY - OCTOBER 25, 2002 - ISSUE NO. 35

Dear Friends and Industry Colleagues,

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.

I have been traveling around the country for almost three months now, and I have decided to live in Portsmouth, Virginia to be close to my family. I have three grown daughters that live here and am really enjoying getting reacquainted with them and my grandchildren. I am still using my Dallas mailing address. That mail gets forwarded to me wherever I happen to be.

WIRELESS NEWS

The good news is that the wireless industry is growing. RCR Wireless News reported this week that: “AT&T Wireless Services Inc. became the first nationwide wireless operator to officially report an increase in its customer base during the third quarter of this year following negative net customer additions from Sprint PCS and Cingular Wireless.” The not-so-good news is that the growth is mostly in telephone side of the business. I walked through a shopping mall the other day looking for some accessories for my cell phone. I wasn't a very big mall but I counted seven stores and kiosks dedicated solely to wireless. There were several other stores selling cell phones and accessories along with their other wares. I only remember seeing one pager for sale in all the places where I looked.

I am convinced that the future for "paging" remains promising but we are going to see many more applications for people paging things, than people paging people. Many years ago, Rob Lockhart at Motorola first started pointing out to the industry that our business can be all of the following:

The first one is our traditional person-to-person messaging. The second is people sending messages or commands to equipment—like an electric company turning off thousands of hot water heaters with a single command over a paging channel for example. This is nothing new. One of the first projects that I worked on at Motorola when I started there in 1974 was a "Load Shedding" system that did exactly that. They used to make a device (called an 800-W Switch) that was shaped like an electric meter which just had a two-tone sequential pager inside connected to a big 30 amp relay. These devices were installed next to hot water heaters and during times of high usage of electricity, the power company could "shed" or turn off, non-essential load. No one ever noticed that their hot water had even been shut off for a while since the heaters are all well insulated. This saved the electric companies millions of dollars because they didn't have to install additional generators just to meet short-term-peak-load requirements.

The third example is the, now routine service, of a computer automatically sending stock market quotation to stockholders, and the fourth is totally automatic (without human intervention) telemetry over a paging channel, where one device (computer or industrial machine) sends a report or command to another "thing." Just think about these applications for a minute! There are many innovative functions we can perform over a paging channel. These paging systems, all over the world, are just sitting there waiting for us to come up with new ways to use them.

TELEMETRY MAY VERY WELL SAVE PAGING
With these solutions we can solve problems for people, and save them money too. A very promising product that we can use to make these things happen is the new Daviscomms TMR (Telemetry Messaging Receiver) This is a one-way FLEX telemetry device which is available in 135 to 174 MHz, 278 to 286 MHz, and 929 to 932 MHz. A POCSAG version is planned for release in the fourth quarter of this year. The FLEX version is now shipping and initial reports from customers are very positive. This product can simply turn things on and off or it can deliver strings of ASCII data. Please let me know if you want more information on this product.

As I have traveled around the country, my cell phone service was great! I have a hands-free headset and my telephone sits in a mouting bracket screwed to the instrument panel—so as I drive down the road I receive all the phone calls to my Dallas number just as if I were sitting in an office back in Texas. Staying in touch via e-mail has not been so reliable. Some hotels and motels have terrible (noisy) telephone lines, and although my ISP in Texas (SW Bell) has roaming-dial-in numbers all over the country, they don't always work as they are supposed to. On my wish list is the new Sony/Ericsson bluetooth-enabled cell phone that will allow my computer to connect wirelessly using GSM GPRS technology.

Today I am sending you this message from the home of one of my daughters that I set up with a high-speed cable modem. Over the next couple of weeks I hope to get settled in an apartment with my own cable modem so I can get back on my regular schedule for this "weekly" newsletter. I have missed sending an issue a couple of times over the last three months.


GOOD DEALS
WANT TO BUY WANT TO SELL

Hi I need a Microlink L20T used or refurbished to hook up to our paging encoder (Glenayre protocol) Where can I find it?

Daviscomms TMR (Telemetry Messaging Receiver). This is a one-way FLEX telemetry device which is available in the following frequency ranges:
  • 135 to 174 MHz
  • 278 to 286 MHz
  • 929 to 932 MHz

I have prepared an information package and ordering guide. If you would like to have a copy, please click here.

We have a colleague in Mexico that would like to buy some pagers: “like, $10 to $15 US Dollars for 1-way and $50 to $75 for 2-way.” (900 MHz naturally) Can anyone help him?  

I would like to recommend Legacy Technologies in the Dallas area for the repair of paging infrastructure. If you need to have Motorola or Glenayre paging equipment repaired, these guys can do it for you. They can handle just about anything in today's paging systems, including satellite stations, GL3000s, GPS, and Unipage/Motorola control terminals. Their work is covered by a warranty and they occasionally have refurbished equipment available for sale. Please contact my friend Virgil Jerrard for more information by clicking here. left arrow Tell him Brad sent you.


If you have any wireless equipment that you would like to buy or sell, please let me know. Everything that is offered for sale in this newsletter is on the honor system. There is no charge for the listing, but if a sale is made, I ask the seller to send me a 10% commission, much the same as the voluntary payments that are requested on the Internet for shareware.


ADIÓS AMIGOS
I am available as a consultant for wireless projects. If you have a requirement for my services, related to paging technology, telemetry, or wireless messaging, please send me an e-mail with a description of your needs.

UNTIL NEXT WEEK
