Nokia has made a high speed data phone call on a commercial 900 MHz band, the first time a high speed call has been made on a frequency that is normally associated with GSM networks. O2 and Vodafone use the 900 MHz band in the UK for GSM. In the 3G calls are made on the 1900 MHz band.
The call was made on Finnish network Elisa with the Nokia Flexi WCDMA Base Station using infrastructure of the existing GSM base station. The move demonstrates the possibility of enhancing the existing 3G network as the 900 MHz band can provide two to four times larger coverage area than the more commonly used 2 Ghz band. It would also give 3G services better coverage indoors due to better signal penetration.
