Nokia Siemens Networks has made the world's first Downlink Dual Carrier EDGE end-to-end call with mobile devices, bringing the promise of doubling today's EDGE network data speeds to a level that will provide support a host of applications such as posting video clips to blogs or streaming news on mobile TV.

Downlink Dual Carrier is a software-based solution, that can double data speeds to 592 kbps on existing EDGE-capable GSM networks, providing a user experience that is akin to 3G.
Nokia Siemens Networks' Dual Carrier EDGE solution, which will be available as a software upgrade is the first step in evolving EDGE. Dual Carrier is based on the 3GPP release 7 standard. Nokia Siemens Networks already has additional plans to introduce in its networks the next substantial step, the so called EGPRS 2B, to further double the end user experience in up- and downlink performance. This will result in downlink speeds of up to 1,2Mbps and will double uplink speed to up to 473kbps – quadrupling of the capabilities of EDGE today.
