[Nokia Siemens Networks Downlink Dual Carrier solution can double data speeds to 592 kbps on existing EDGE networks.]

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. As a strong innovator of EDGE Evolution, 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 1.2 Mbps and will double uplink speed to up to 473 kbps, thus quadrupling of the capabilities of EDGE today.

GSM/EDGE operators can serve their customers even better using the Dual Carrier solution as the demand for data services and connectivity is booming, proven by the steep increase on mobile broadband traffic in 3G/HSPA networks today. With Dual Carrier solution, also 3G/HSPA operators can offer better service continuity for their data services.

Nokia Siemens Networks GSM/EDGE BSS is operational in more than 280 operator networks in 127 countries offering services to more than 1.5B subscribers. Nokia Siemens Networks is the indisputable no. 1 in EDGE with 139 public EDGE references.
