My latest presentation: This is it! This is where I see the paging business going, and I think that most of my colleagues agree. It's not just Paging anymore! In spite of recent unfortunate developments in the wireless industry, wireless data services of all types have a good chance of success.
For over ten years we have been trying to tell the public that it's Wireless Messaging, or Wireless Data not Paging . It looks like it is really catching on now with two-way technology. Want to know what's really going to be hot? Wireless e-mail using the new Motorola T900 two-way pager! You heard it first here. The original PowerPoint presentation can be downloaded by clicking on this link.

|Why ReFLEX™ is better: ||This is a PowerPoint slide presentation by Allan Angus, PE, of WebLink Wireless in Dallas, Texas. It addresses the number one hot topic in the wireless industry today. Why is ReFLEX better ? This is a "must read" paper for everyone wanting to be up-to-date on the latest information about wireless messaging protocols. Allan Angus is recognized by many as the industry's leading wireless technologist. He is certainly the one that I go to frequently with my questions, which he always patiently answers.|
|ReFLEX RULES: |
A very well written paper—126 pages long. It takes a while to download, but it's worth the wait.

Ericsson's ReFLEX vs. Mobitex paper takes the opposing view that Mobitex is better than ReFLEX:
(To be fair, I report both sides of issues whenever possible.)
ReFLEX vs. Mobitex
ReFLEX vs. Mobitex Please note that these papers, debating the merits of Mobitex and ReFLEX, are out of date now. They are approximately eight years old. Remember that this is 2008 and we are paying over $3 dollars for a gallon of gas and $10 for a good hamburger and fries — so factor that into any pricing that you see. Comments and/or corrections are welcome.

Versions of Two-Way Paging
Do you know the difference between one-and-a-half-way paging, and "full" two-way paging.? Here is a brief description of the different versions of two-way paging.
The original Wheel of Fortune:
The Wheel of Fortune
The Wheel of Fortune concept explains how to increase revenue in a paging business by offering a multiplicity of services, some of which operate in off-peak time so as to not degrade the paging system's efficiency during regular traffic hours. This version is a little dated. Please also see: The New Wheel of Fortune for a more up-to-date revision.
I created this presentation while training my manager at Motorola on all the things you can do with a paging system (circa 1991). The concepts are mine; he thought of the title. It later became very popular, and many paging operators around the world continue to use these ideas in their businesses today.
Is Paging in trouble?
You must read this if you are interested in paging:
|"Paging's Future" This article was reprinted in 5 or 6 newsletters when I first published it in February 1997. I still stand behind the statement that paging is not dying. One-way paging is certainly diminishing, but two-way paging is really coming on strong. The overall result will be tremendous growth as shown on the forecast immediately below from DLJ.|
|U.S. paging forecast:||This is by Donaldson, Lufkin, & Jenrette, 1999. It is sad that paging took a downturn, but I am leaving this forecast here to show how bright the future looked in 1999. [very obsolete]|
|The Latin American paging market:||Some thoughts on the Market Outlook in Latin America. This one is a little old now, but still interesting.|
|Two-way voice paging:||I wrote this when Two-way Voice was just starting.|

|CCIR Recommendation 584 - The POCSAG protocol:||The complete POCSAG specification: Radio Paging Code No. 1 , in its original form.|
|The recommendation for the POCSAG protocol:||The original recommendation of the POCSAG committee to the CCIR: Included here for its historical value only.|
|The alphanumeric paging entry protocol:||I received a request for the Alphanumeric Entry Protocol , so I have included here. It is known as "TAP" (Telocator Alphanumeric Entry), "PET" (Personal Entry Terminal) and sometimes as "iXO" after one of the first companies to manufacture a small alphanumeric entry device using this protocol. All three names refer to the same protocol. This is not the official PCIA version, but it works for basic alpha-entry programs.|
A correction was posted here on 3-18-02 giving credit for inventing this protocol to Mike Suchoff. Evidently the previous story, as told to me by a friend, was erroneoussorry Mike.

|A reference paper on paging protocols:|
Paging Protocol Reference Paper
This is an interesting and comprehensive paper by Jay Moskowitz explaining most of the various protocols used in paging and wireless messaging. It includes Input Protocols, Inter-System and Intra-System Protocols, Transmitter Control Protocols, Pager Protocols, and Host Computer Protocols. This is the best article on paging protocols that I have been able to find.
I have worked with and for Jay Moskowitz a couple of times in my career. He was the founder of RTS Wireless , Senior VP of Engineering for Spectrum Communications and Electronics Inc. , and creator of Tickertec™, a 1977 stock market alerting system that was eventually extended for the generation of stock market alerts to text pagers.
These are the two best engineering whitepapers that I know of — about the complex issues of high-speed-digital paging.
The first one “FLEX at 6400 bit/s” was written by my friend and colleague, Allan Angus, PE. (He patiently taught me a lot about Paging.). He was the senior technologist and system architect at PageMart/WebLink. PageMart Wireless later became WebLink Wireless and then was acquired by Metrocall. Arch and Metrocall merged and then became USA Mobility.
The companion paper to this one is: “Pitfalls on the way to high speed paging from the service provider’s perspective”, by Selwyn E. Hill, who was a senior RF engineer at PageMart/WebLink and who also patiently taught me a lot about Paging.

|K9IQY Project Page|
My latest project is a general coverage radio receiver, tuning from audio frequencies to 30 MHz in one Hertz steps — locked to the GPS constellation. The "dial" is a 24" color monitor connected to a laptop showing a 190 KHz window of the band as a spectrum analyzer. I have been involved with many kinds of radio receivers for over fifty years — amateur, military, and commercial. This modified SDR-IQ is a dream come true. When I was a young ham, I dreamed of the day when I might have a receiver that would read out to one kilocycle (before we used the term Hertz). Now I have assembled one that reads out to one Hertz and is accurate to ± 70 µHertz* — and thanks to GPS — it will maintain this accuracy as long as the GPS satellites keep working.
* Please note µHertz is microhertz not millihertz .

|GSM Disaster Relief Report|| The Role of Mobiles in Disasters and Emergencies |
A spate of natural disasters and other emergencies during the past two years has prompted new interest in how technology can help enhance our security. This report assesses the impact that the widespread availability of mobile phones has had on the recovery from specific disasters and atrocities, such as the Indian Ocean tsunami, Hurricane Katrina, the summer floods in central Europe, and terrorist attacks in Istanbul and London. (This report was prepared by Enlightenment Economics, a consultancy specialising in the impacts of technology and globalisation.)
