Nokia Siemens Networks completed the world’s first Downlink Dual Carrier EDGE end-to-end call with mobile devices. 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 said it 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 current EDGE networks.
The company noted that its GSM/EDGE BSS is operational in more than 280 operator networks in 127 countries offering services to more than 1.5 billion subscribers.http://www.nsn.com
