Finland's Nokia sees world mobile network
By Roland Moller
HELSINKI, Finland (Reuters) - Mobile phone makers will be able to build handsets that will work almost anywhere in the world due to recent breakthroughs in standardization, Nokia's head of research and development Yrjo Neuvo said Thursday.
Neuvo told Reuters in an interview that the planned third generation systems -- wideband CDMA, UWC 136, which is based on TDMA, and CDMA 2000 -- would not be identical but close enough.
''The variations will be so small that it will be easy to make phones that service all third generation networks if market demands make it feasible to take the extra cost of managing multiple frequencies,'' he said.
Last December, the Universal Wireless Communications Consortium (UWCC), which groups mostly U.S. companies, agreed with the European Telecommunications Standards Institute (ETSI) to seek a global standard and avoid technical duplication.
Neuvo said this was a little understood breakthrough for bringing the future GSM and TDMA systems close enough to each other to making handsets work across different networks.
Nokia possesses all the key know-how and technology for third generation phones and infrastructure for the two main standards, wideband CDMA and UWC 136, although most of its efforts are in wideband CDMA, Neuvo said.
Wideband CDMA (Code Division Multiple Access) combines features of CDMA, which is used in the United States with the European and Asian GSM (Global System for Mobile Communication). UWC 136 is a wideband version of another U.S. system TDMA (Time Division Multiple Access).
First generation mobile phones were analog systems and the second generation are digital systems such as GSM.
Third generation systems will boost mobile data speeds to hundreds of kilobits per second compared to the 9,600 bits per second on current GSM systems.
While the wideband 3G (third generation) technology will be key to very fast wireless data transfer, GPRS (General Packet Radio System) will improve GSM and TDMA substantially and make it possible to offer better value-added services, Neuvo said.
Nokia has said it will launch GPRS in 2000.
GPRS is a way to faster transfer speeds -- the top speed can rise to more than 100 kilobits per second -- by freeing more channels available for one user and by packaging the signals.
GPRS will also make it possible to make phones receive electronic mail or messages from databases without the recipient actively downloading them, much like short messages are received today but much faster, Neuvo said.
GPRS will greatly improve Internet-based services for phones with Wireless Application Protocol (WAP) functions, he said.
Some operators such as Finland's Sonera have already ordered GPRS system upgrades. As they start providing new services, such as electronic mail for mobile phones, they will be encouraging users to demand even more advanced services, Neuvo said.
While future third generation mobile phones will give users new services, the early third generation models will also work on older networks as part of the changeover to the new system, Neuvo said.
Mobile phone industry leaders Nokia, Ericsson and Motorola are in a particularly strong position due to the high level of software in the value added services that will emphasize the economies of scale, analysts said.
