Brian, I am a telcom investor, but not a "techie". Does this count? Nokia in Third Generation Mobile For third generation cellular mobile networks, Nokia has promoted an evolved GSM core network/Wideband Code Division Multiple Access (WCDMA) radio air interface to realize sophisticated wireless multimedia services of the future. This approach also provides operators an evolution path forward that maximizes their investments in present GSM systems. The unanimous decision by the European Telecommunications Standards Institute (ETSI) in January to adopt a WCDMA air interface using Frequency Division Duplex Mode (FDD) in the IMT-2000 designated 2 GHz paired bands with a provision for Time Division Duplex (TD-CDMA) in unpaired 2 GHz bands (see diagram) for Universal Mobile Telecommunications System (UMTS) was a welcomed outcome. In WCDMA, Nokia has had a sophisticated test system and has carried out extensive evaluations on its suitability for third generation mobile systems since 1992. For the core network, General Packet Radio Services (GPRS), Asynchronous Transfer Mode (ATM) in both switching and transmission, and Internet Protocol (IP) are all key technologies for third generation systems that are under intense development in Nokia. Committed to open networks, Nokia is actively participating in the standardization of an open interface between third generation radio access and the core network elements (the GSM A-interface), and signaling between different core network elements (MAP interface), allowing multi-vendor networks. Development is also currently underway in Nokia for highly sophisticated user terminals for third generation networks that will support, among other capabilities, multimedia services and advanced imagery. Nokia will soon demonstrate its first prototype WCDMA systems. nokia.com
