Nokia and T-Mobile have completed High Speed Downlink Data Packet Access (HSDPA) calls using Nokia's 3G network technology. The calls were made in T-Mobile's live network in the UK, the Netherlands and Germany, and are the result of the strong collaboration between the two companies to deliver HSDPA to the commercial networks. The solutions will now be used to further progress testing with T-Mobile prior to commercial launches.

"The HSDPA calls demonstrate T-Mobile's commitment to raising the bar for the quality of broadband mobile data services," says Hamid Akhavan, Chief Technology Officer, T-Mobile. "The calls are a good example of the successful cooperation that is taking place between T-Mobile and Nokia in the field of high speed mobile access and broadband applications."

"Nokia is pleased that the collaboration with T-Mobile has resulted in successful HSDPA calls, which demonstrate that Nokia's HSDPA solution is ready to support operators leveraging their mobile data opportunities," says Kari Sundback, Vice President, Networks, Nokia. "We will continue to work very closely with T-Mobile in the UK, the Netherlands and Germany in preparing their networks for commercial HSDPA launches."

The Nokia HSDPA solution is a software upgrade to the WCDMA 3G network that offers end users significantly faster download speeds - up to 1.8 Mbps in the first phase, compared to 384 kbps on standard WCDMA 3G networks. Operators upgrading their networks with the Nokia HSDPA solution can take advantage of improved data rates and throughput, enhancing the efficiency of the network to support a higher number of users at a lower cost per user. The Nokia HSDPA solution allows operators to provide enhanced end-user services at significantly lower cost per bit.

Later, an upgrade to High Speed Uplink Packet Access (HSUPA) with enhanced upload speeds, will be available in a similar manner. Nokia upload speed is already 384 kbps. Nokia already has over 20 HSDPA contracts, 7 of which have been published.
