Dear Friends and Industry Colleagues,

I hope this finds you in good health and happiness. Thanks to everyone who helped forward last week's newsletter and get new subscribers. More new subscribers were added in the past week than ever before. Also, special thanks to my friend Enrique Llaca in Mexico City for the interesting news article that he sent in. I have translated it into English. Jay Moskowitz was very pleased; he received several responses to his request for help with his patent issues last week.

There are two more items of interest this week. One is the special report on Terrorist Alert Notification that I promised you last week, and the other is the first of a series of feature articles on Vytek Wireless paging products. Several paging companies have asked me where they could purchase new paging infrastructure. I am happy that I can now offer you some very good equipment made by Vytek Wireless Products.

Impacta el IEPS en los beepers


La aplicación del Impuesto Especial sobre Producción y Servicios (IEPS) ha impedido a los operadores de radiolocalización de personas realizar las inversiones para aprovechar sus frecuencias y su tecnología en el desarrollo de nuevas aplicaciones como el servicio de doble vía, el cual tiene un enorme potencial.

Hasta el 2002, la industria del paging había realizado inversiones en activos fijos superiores a los 50 millones de dólares, adicionales a los 8.4 millones de dólares por el pago de frecuencias, pero este año no efectuó inversión alguna. Un estudio realizado por el despacho Lozano y Asociados señala que el impacto de la aplicación de dicho gravamen no ha sido similar en los diferentes subsectores de las telecomunicaciones, ya que algunas industrias como la del paging recibieron "el tiro de gracia", pues la migración de muchos de sus clientes hacia otros servicios como la telefonía celular bajo el sistema de prepago o al trunking, aunada a la aplicación de este impuesto, implicará al término de este año una reducción cercana al 50 por ciento en el número de suscriptores.

Lo anterior significaría que a este ritmo, la industria prácticamente habrá de desaparecer en un periodo máximo de 2 años. De 1999 al 2001, el número de usuarios de radiolocalizadores creció a un ritmo promedio de 41 por ciento anual. Hasta agosto de este año, a partir de la aplicación del IEPS, el número de suscriptores se redujo 32 por ciento.

Además de la crisis que vive esta industria, la Secretaría de Hacienda no logró su meta recaudatoria. Se estima que al cierre de este año el monto que recaudará el erario público por concepto de impuestos, derechos y aprovechamientos incluidos los 71.4 millones del IEPS, será 17 por ciento menor a lo recaudado en el 2001. El estudio fue realizado por encargo de la Asociación Mexicana de Concesionarios de Radiolocalización.

Mensaje pesimista
Advierte estudio que en 2 años podría desaparecer este servicio. Si se hubiera mantenido el crecimiento promedio de la industria de telecomunicaciones en los últimos 3 años (que había crecido a un ritmo del 17 por ciento), se habría generado una recaudación fiscal adicional sin necesidad de crear nuevos impuestos, y se habrían generado mayores empleos e incentivado nuevas y mejores tecnologías.

Impact of Special tax on beepers


The application of a Special Tax on Production and Services (IEPS) has kept radio paging operators from making investments to take advantage of their frequencies and technology in developing new applications such as two way service, which has an enormous potential.

Up to 2002, the paging industry has made investments in fixed assets [infrastructure] of over 50 million dollars in addition to the 8.4 million dollars paid for frequencies; however, this year there was no investment at all. A study made by the offices of Lozano & Associates shows that the impact of the mentioned burden has not been the same as in other sub-sectors of telecommunications, since to industries such as paging this is a coup de grace—because the migration of many of their clients to other services such as cellular telephone with prepaid service, or to trunking, along with the application of this tax, will cause, by the end of this year, a reduction of close to 50 per cent in the number of subscribers.

The above would indicate, at this rate, that the industry will practically disappear in a maximum period of two years. From 1999 to 2001, the number of paging users grew at an average rate of 41 per cent per year. Up to August of this year, since the application of the IEPS tax, the number of subscribers was reduced by 32 per cent.

In addition to the current crisis that this industry is experiencing, the Secretary of Treasury did not achieve its collection objective. It is estimated that by the end of this year, the amount the state will collect from the public in taxes, duties, and assessments including 71.4 million in IEPS tax, will be 17 per cent less than the tax revenue in 2001. This study was sponsored by the Mexican Association of Paging Carriers.

Pessimistic Message
The study points out that in two years this [paging] service could disappear. If the average growth of the telecommunication industry had been maintained over the last three years (if it had grown at an annual rate of 17 per cent), it would have generated additional fiscal collection without the necessity of creating new taxes and it would have generated more employment and stimulated new and better technologies.


On Sunday afternoon, December 8, 2002 a virus infected the server in Houston where my web site resides. For about three hours there was an offensive message that replaced the first page of Obviously, it was not from me, or the ISP— iland Internet Solutions Corporation, or from The situation has been corrected. I sincerely apologize to anyone who may have read the offensive message. The virus cannot be transferred to anyone's computer who visits this site.

Hi Brad

Have followed your web site for many years.  Glad to see you keep it alive.  I spent quite a few years in the business here in Canada operating a company called DataMax Paging.  I kick myself for all of the paging goodies that I have discarded which is why I am emailing you.

I am looking for working samples of the early messaging cards from Motorola.  The early NewsStream module that worked with the HP95LX, The Type 2 cards that Motorola originally made for HP's StarLink service.

Also looking for an NEC D4 alpha and the optional Printer/RS232 package for the D4.

I was born during World War II. I heard a lot about the war as I grew up. I heard about it from one uncle who came back from the war and I used to hear my mother crying about another uncle who didn't come back. He was killed in France by a German machine gunner. War is a terrible thing. I must have watched a million movies about the war in my lifetime. I felt like the bombing of London happened in my own country. Later as a kid in school, we used to have nuclear bomb attack practice when we had to get down and take cover below our desks. How many times did we hear “the Russians are coming?”

When I became a ham radio operator at age 15, the government required us to monitor an AM broadcast station and to immediately cease transmitting if the station went off the air. They were concerned that bombers might follow a radio signal to a target. This was called CONELRAD, which was acronym for "Control of Electromagnetic Radiation." Beginning in 1953, all new AM radios sold (FM wasn't that common in those days) were required to be marked with a "Civil Defense" triangle at 640 and 1240 on the dial. I'll bet some of my readers will remember the little jingle that they used to frequently sing on the radio: “Six forty, twelve forty, CONELRAD!”

I must admit that I am more than a little shocked that we seem to be taking the current war so lightly. We have the technology today to alert the public about threats to public safety. More people are carrying wireless devices than ever before. Within seconds we could alert millions, but we don't.

Do you realize that many police departments still warn citizens about local emergencies by knocking on people's front doors? Some of the more modern ones use Automatic Telephone Dialers. They now use the same auto dialers that telemarketing people use. I got a call from the police the other day offering a reward for tips about stolen property being offered for sale in my town.

Following is a short report on the whole issue of electronic emergency notification. Maybe it will get someone thinking about how we can implement Terrorist Alert Notification.

NOAA – One of the Best Kept Secrets on the Web

The NOAA says that their Weather Radio “is an all-hazards radio network, making it the single source for the most comprehensive weather and emergency information available to the public.” In other words, weather radios won’t just give you weather warnings. They’re also tapped into the FCC Emergency Alert System – which means that if and when the President decides to issue an alert about a national emergency, it will go directly to your Weather Radio.

Though the system could have been used on September 11, President Bush went directly to the broadcast media instead. The President’s decision to forego an EAS alert sparked a quiet, though heated national debate about how the EAS should be used. Is it exclusively a warning system? Or can it be used to report incidents after the fact as well? A good summary of both sides of this debate is available at Radio World Newspaper.

RDS (Radio Data System), a technology that originated in Europe, allows broadcasters to silently deliver a 1,200-bits-per-second stream of data along with the audio content to car radios, providing drivers with a variety of capabilities, including:

90% of broadcast stations have RDS capability in Europe. I remember hearing that one of the motivating factors for the development of RDS was the assassination of the Prime Minister of Sweden. Had RDS been in place then, they might have caught the perpetrator.

During the Persian Gulf War, 12 to 13 years ago now, my telephone at home rang early one morning. I immediately recognized the voice as that of my old friend, customer, and fellow ham radio operator, Froike Biegun at Beeper Israel. I had been intently watching the television coverage of operation Desert Storm and so I knew about the SCUD missiles being fired at Israel. Froike explained that the incoming missiles could be detected on RADAR just a few minutes before they hit. This was barely enough time to sound the early warning sirens and for everyone to take shelter. Everyone that is, except for deaf people.

So Froike's idea was to distribute vibrating pagers on one common capcode to alert the deaf community. They needed more pagers—and in a hurry! He called me because of our long-standing friendship and because I was the International Market Manager for pagers at the Motorola factory in Boynton Beach, Florida.

I got dressed and went into work where I invoked a Motorola policy to do everything possible in a public-safety emergency when human life and property were at risk. We literally stopped the production lines, manufactured the pagers, and air-lifted them to Israel in the space of a couple of days.

During the "Desert Storm", when Israel was under attack by Iraqi SCUD missiles, early warning sirens could not be heard by the deaf community. At that time, I worked in the capacity of Deputy Director, Engineering and Operations, Beeper Communications Israel Ltd.

Beeper distributed 1,200 vibrating pagers alerting the deaf to take cover. As Beeper stock of same pagers was limited, we have approached Mr. Brad Dye, International Market Development Manager at the Motorola paging factory in Boynton Beach, Florida, to provide a required number of vibrating pagers. Our request was fully and timely met.

Today, possible US attack on Iraq and consequent Iraqi similar attack on Israel, Beeper has distributed 5,000 vibrating pagers, out of total order of 10,000, to the deaf community. Those vibrating pagers are manufactured GSL, China since Motorola ceased to manufacture Hebrew version pagers.

Best regards,

With the recent addition of the 32nd AAMDC to the joint coalition task force, soldiers on the ground now have access to a new early warning system. This system, which is basically a redundant system relying on digital pagers, can alert soldiers to possible biological and chemical agents before they are released by incoming Scud missiles, said Lt. Col. Thomas A. Gray, the battle captain for the 32nd AAMDC force protection tactical operations center.

“The problems of the deaf and the blind are particularly apparent in the time of alarms. The deaf cannot hear the siren or radio and TV announcements and the blind are subject to the stress of having to find their way, seal their poison-gas proof rooms and then there is their dependence on seeing-eye dogs. Some thought has been given to these problems, with sensitivity to the added strain placed on relatives and neighbors of these disabled people. The deaf have now been provided with buzzers whose vibrations indicate the beginning and end of an alarm. There are plans, not yet implemented to add words to the TV screen announcements that report the progress of the alert, important to all of us or using signers to spell out the announcements. The blind now have a muzzle-based mask for their dogs, a benefit to all large dog owners.”
