A group of four mobile telecomms suppliers, pushing a new radio communications standard for Europe, has won the backing of Bosch and Motorola.
Bosch and Motorola now join Alcatel, Italtel, Nortel and Siemens to lobby ETSI, the European standards body, to consider a radio access solution that combines the TDMA and CDMA specifications. They propose their technology should provide the standard radio access facility for the EC-backed Universal Mobile Telecommunications System (UMTS), which will provide a third generation mobile infrastructure for Europe.
The support of Bosch and, in particular, a US giant, Motorola, will be a blow to a rival approach to radio access, wide band CDMA, backed by Europe's Ericsson and Nokia. However, Ericsson and Nokia both agree with the other players that the basic network for UMTS should be based on 'evolved core GSM' - a development of the current European mobile standard, GSM.
According to Alistair Urie, director of product strategy at Alcatel, the use of evolved core GSM would provide current GSM with a smooth migration path and enable dual GSM/UMTS phones to be used on both existing and future GSM networks. Meanwhile, a combined TDMA/CDMA standard for radio access would enable systems to easily send and receive voice and data.
ETSI is due to meet next month to decide which proposals to put forward to the global standards body, the International Telecommunications Union, next summer.
