MONTREAL, Canada, and SCHAUMBURG -- Telesystem International Wireless Inc. (TIW), through its subsidiary Dolphin Telecom plc (Dolphin), and Motorola, Inc. (Motorola) have formed a wide-ranging strategic relationship for the deployment of TETRA in Europe. It includes infrastructure and handset business agreements valued in excess of US$400 million, in part, for the deployment of a digital wireless communications network in Germany and the purchase of up to 400,000 second-generation TETRA handsets from Motorola. The relationship represents Motorola's largest agreement to date for the deployment of TETRA-based equipment in Europe. TETRA is the European standard for enhanced specialised mobile radio (ESMR) wireless services. Work on the German nationwide network will begin immediately and initial services are targeted to be available in 2000.

In conjunction with the infrastructure contract, Dolphin's German subsidiary, Dolphin Telecom (Deutschland) GmbH, obtained a vendor-facilitated DM800 million (approximately US$450 million) debt financing commitment to fund the rollout of Dolphin's wireless network in Germany and associated working capital requirements, as well as a bridge financing of up to $125 million to fund Dolphin's investment in Germany. The various financing commitments are subject to the completion of certain conditions including the negotiation and execution of definitive agreements and the receipt of certain approvals.

"Motorola has played a pioneering and very successful role in the deployment of enhanced specialised mobile radio (ESMR) services in North America," said Yves Marois, president, Europe of TIW and chairman of Dolphin. "We are very excited to have Motorola share and support our vision of a pan-European digital wireless communications network based on TETRA with such an important commitment to its success," added Yves Marois.

William Spencer, senior vice president of Motorola, said, "We are very excited about our strategic relationship with TIW and its subsidiary Dolphin, and we are pleased about the opportunity to support Dolphin with both our technology solution and by providing assistance in the financing of their European rollout. The strategic vision Dolphin has shared with Motorola represents exciting opportunities for both of our organisations in Germany and other European markets. Dolphin is executing on a tremendous business opportunity for ESMR in Europe, and we believe this enhanced, multi-functional product and services offering will provide important benefits to users throughout the region as it does today in other parts of the world."

Dolphin already is deploying TETRA networks in both the United Kingdom and France and expects to launch initial commercial ESMR services during 1999. Dolphin's German TETRA infrastructure contract, which represents Dolphin's first infrastructure agreement with Motorola, will facilitate the creation of a seamless digital wireless network among the three countries in the year 2000.

"Motorola proved to be the winning choice to design, manufacture, install and maintain our TETRA network for Germany. We are very confident in its ability to deliver this first phase of the contract - a nationwide digital wireless communications network in Germany, and ultimately the largest single nationwide TETRA network in Europe," said Ted Beddoes, chief executive officer of Dolphin.

Eike Baer, corporate vice president of Motorola, added, "We are delighted that a contract of this significance has been awarded to Motorola. This is another important milestone adding to the success of TETRA and a contract of this size demonstrates Motorola's commitment to this European standard. This is the largest TETRA commitment awarded to date and is in addition to the 150,000 TETRA handset order Dolphin awarded Motorola last June."

Dolphin, which groups TIW's specialised mobile radio (SMR) and ESMR activities in the United Kingdom, France, Germany, Belgium, Spain and Portugal, is the largest SMR operator in Europe, serving approximately 300,000 subscribers and with licenses covering a population of more than 230 million.

TIW is a global wireless operator. It develops, acquires, owns and operates wireless telecommunications networks in developing and developed markets throughout the world. In addition to SMR services provided by Dolphin in Europe, TIW provides digital cellular services in Romania, Brazil, India and China as well as paging services in Mexico and the Netherlands. TIW is listed on the Montreal Exchange and the Toronto Stock Exchange under the symbol "TIW" and on the Nasdaq Stock Market under the symbol "TIWI."

Motorola has an extensive TETRA client base throughout Europe including the Basque Government in Spain, Government of Hungary, Copenhagen Metro in Denmark, Dolphin Telecommunications, and States of Jersey Police. Motorola's success with TETRA is not restricted to Europe - it also has been awarded a contract to supply a Motorola TETRA-based system (Dimetra) in Asia.

Motorola is a global leader in advanced electronic systems and services. It liberates the power of technology by creating software-enhanced products that provide integrated customer solutions and Internet access via wireless and satellite communications, as well as computing, networking, and automotive electronics. Motorola also provides essential digital building blocks in the form of embedded semiconductors, controls and systems. Sales in 1998 were $29.4 billion.

I have looked back over the last year's posts but find no discussion about possible adverse health effects from TETRA masts or handsets whatsoever. In the UK this os now a major issue. Has anyone involved in this system ever conducted any heakth effects, given that the handsets can exceed the ICNIRP regulatory guidelines, especially when data or video is being received.

The TETRA MoU has an area about Health & Safety concerns at

You say that TETRA handsets exceed ICNIRP requirements when data or video is being sent, but I have not come across this in any reports myself.
- Do you have any reports that I could look at to see your concerns?

The work that Home Office has been doing in the uk has not shown any measurable effects so far, I understand.

Also TETRA has mandatory open loop power control in the standard, and this has to be implemented in order for a radio to be standards compliant.

I believe that this can be check for operating correctly using a TETRA test set, such as the 2968 from Aeroflex (formally IFR.)
- Operators such as Airwave mmO2 Limited are checking for operation of OLPC before giving network approval.

OLPC means that the handsets would be operating on the lowest power setting needed to operate on the network.

Also, since TETRA is a TDMA system why would the number of timeslots being used cause the ICNIRP guidelines to be exceeded?

These are, of course, all my own views and do not necessarily reflect the views of my employers.

Kind Regards,

Thanks for telling me about the right place to address health issues! I thought there must be somewhere.
Re exceeding ICNIRP:


This issue has also arisen with GPRS.

It isn't usually an issue when data in being downloaded by the
mobile unit as the extra slots are Rx only (if your system
software allows different numbers of Tx/Rx slots to be used in

However if uploading data from the mobile unit, some mobile
phones and some TETRA handsets (not necessarily the low 1 watt
power Airwave ones) will exceed ICNIRP if they transmit at full
power in more than one TDMA time slot as they are already over 1
W/kg SAR when driving just one slot at full power.
2 slots = 2 x power. 3 slots = 3 x power. 4 slots = 4 x power.
If they were all transmitting at the same power.

However, I am a biologist, not a radio engineer, and have to rely on those with greater knowledge than I!

best, Roger Coghill

Actually, I didn't mention the results of 2nd Quarterly report from DSTL which, though only in graphical form seems to show an impact on calcium in cerebellar granular cells when the TETRA signal was switched on, and another (enduring long post-exposure) when it was switched off. The sham exposed cells showed no such movement. It looks a significant result (about 50% uplift) but so far i haven't seen any numerical data. The graph is also shown in the 3rd Quarterly summary report.

Hello Roger,


Again here are my own personal views and not those of my employer.

You mention in your post and on your web-site that there are some measurements shown for Calcium ions in Figure 7 which is in the 3rd DSTL report on investigations in to TETRA.

There does appear to be some measurements present, in the 4th 10-minute period.
- The sham exposed values seem to also show some measurements in the After part of the Figure 7 graphs.

However, as an engineer and not a biologist, I do not know whether these measurements are significant or not. They should probably be discussed though.

In your paper, you suggest that TETRA uses an ELF signal.

However, this is incorrect because it uses a UHF carrier frequency of about 400 MHz, which is pi/4 DQPSK modulated.

For a TETRA handset, the transmitted signal is turned on and off with a 17.6 Hz periodicity if the handset is only transmitting in 1 timeslot of 4.
- This then is an ELF component which is Amplitude Modulated onto a 400 MHz UHF carrier wave.

Therefore, the communications range of the signal will be determined by the carrier wave frequency, and not its modulated component.
- This would be the same physics as for AM radio in the Medium wave band.

I think that follow-up studies need to be continued, such as those announced in May 2003 by the UK Home Office.

However, annecdotaly, I have not seen any evidence that TETRA has caused any health risk to myself or to the people who are already using it for communication.

I think, as a responsible engineer, that we should keep a watching brief on what is being experienced.

However, I have not seen any evidence of harmful effects to date.

Again, these are my own personal views and not necessarily those of my employer.

Kind Regards,
