The Nokia HSDPA offering is a software upgrade to the WCDMA 3G network that offers significantly faster download speeds - up to 1.8Mbps in the first phase, compared to 384Kbps on commonly deployed WCDMA 3G networks.
Nokia promised that an upgrade to High Speed Uplink Packet Access with enhanced upload speeds will be available using a similar upgrade process.
Hamid Akhavan, chief technology officer at T-Mobile, explained that the successful trial will allow the operator to deliver HSDPA in its commercial networks.
"The calls are a good example of the successful co-operation taking place between T-Mobile and Nokia in the field of high speed mobile access and broadband applications," he said.
Kari Sundback, vice president of networks at Nokia, added: "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."
