By Emily Bourne, Total Telecom 09 July 2001 Germany's Siemens and its 3G infrastructure partner, NEC, claim seven operators have successfully tested voice calls under "real life conditions" over 3G networks provided by the partnership. A spokeswoman for the German vendor explained that this refers to "over the air" calls using prototype handsets. "We had devices that look like mobile phones," she said. "Often [3G tests] use two base stations that are communicating with each other." The tests were conducted in Germany by T-Mobil and D2 Vodafone, in Austria by T-Mobil and max.mobil, in Monaco by Cegetel, and in Italy and Finland by unnamed operators. The prototype handsets were provided by NEC. In addition, a trial video call was conducted by BT's Manx Telecom on the Isle of Man, transmitting pictures from handset to handset. Manx Telecom planned to be the first in the world to commercially launch 3G, but has delayed the launch to late summer. "With these test runs completed successfully UMTS/3G has left behind the lab trial phase and proven reliable under real life conditions," claimed Lothar Pauly, member of the board of Siemens IC Mobile. "With the market being hit so much, to be able to say an infrastructure supplier has provided a network that works with a prototype terminal is good news," commented Jason Chapman, a senior Gartner analyst. However, he warned, it is crucial to demonstrate actual mobility rather than just a live connection between handsets. Manx Telecom, for instance has had problems with the handover from one base station to another and from one controller to another, said Chapman. “As long as you stay within a single base station coverage area, it seems to be up and running, [but if you move out of the range of that station, the call cuts out],” he explained. Chapman said the operators' priority at the moment is "making sure GPRS is running," and their number two priority is to get handsets working. "The window for GPRS is increasing," he added. Original 2002 launch dates have been put back to 2003-4. "Having GPRS means the whole market can experiment and educate themselves before the launch of 3G, when they can't afford to make errors," he said. The seven voice trials may not seem to be important, seeing as the key to 3G will be the take-up of high data rate services, but getting packetized voice to work is critical, said Chapman. "Voice is not necessarily a sexy service, but to make sure that a connection exists is critical for video-streaming and real-time applications." Siemens and NEC have signed 3G infrastructure contracts with 17 operators (most 3G contracts are multi-vendor). These operators are: Austria: max.mobil Denmark: Telia Finland: Radiolinja, Telia Germany: D2 Vodafone, T-Mobil France: Cegetel/SFR Isle of Man: Manx Telecom Italy: TIM, H3G Monaco: Monaco Telecom Norway: NetCom Portugal: ONI Way, TMN Spain: Amena United Kingdom: Hutchison, One2One.
