WCDMA data call on 900 MHz band
Wednesday, January 10th 2007 - 01:16 CET
Nokia and Finnish telecom operator Elisa today carried out the world's first WCDMA/HSDPA data
call on the 900 MHz band in a commercial network. The call was conducted in Elisa's live network in
Finland, and the equipment included the Nokia Flexi WCDMA Base Station with a special solution for
sharing the site infrastructure of the existing GSM base station.
WCDMA 3G network
The call demonstrated a new possibility of enhancing the existing WCDMA 3G network. The 900
MHz band can provide 2-4 times larger coverage area than the most commonly used 2 GHz band, thus
reducing network deployment costs significantly especially in the rural areas. It also improves the
availability of 3G services indoors due to better radio signal propagation characteristics. Finland is
among the first countries that have allowed WCDMA 3G operation at 900 MHz band.
Nokia Flexi Multiradio Combiner
Nokia Flexi WCDMA Base Station and Nokia Flexi Multiradio Combiner enable Elisa to share their
existing GSM900 base station site, including base station cabinets, antenna lines and power feeders,
with the WCDMA 3G network. Utilizing Nokia's solution, the network operator can provide
broadband wireless type of services, such as High Speed Packet Access (HSPA), for end-users in a
very cost-efficient way.
