Nokia Siemens Networks says that it has conducted a trial with an unnamed Chinese mobile network operator to conduct the world's first successful trial of EDGE Evolution Downlink Dual Carrier (DLDC).
The technology doubles data speeds on EDGE networks enabling end users on a GSM network, and also considerably increases system resource efficiency, enabling more end users and data traffic through existing GSM networks.
By enabling an efficient and cost effective use of available transceiver resources, it ensures that when 3G users move into an area without 3G coverage they can switch into the GSM/EDGE with minimal change in end user experience.
Nokia Siemens Networks initially conducted the trial in its Beijing development center before replicating the process in the live network of the unnamed Chinese operator.
"The success of this trial underlines the tremendous efforts we have put behind GSM evolution, giving us a clear lead over our competitors by at least half a year," said Prashant Agnihotri, Head of GSM/EDGE Product Management, Radio Access, at Nokia Siemens Networks. "While we are extremely proud of this worldwide technology first, we are more excited with the immediate and significant benefits for our customers. Securing seamless user experience in a country where 3G is in the process of being rolled out, enables us to truly support China's next phase of growth."
In addition to improving current radio networks' efficiency and protect operator investment towards future evolution, EDGE Evolution DLDC will positively influence GSM/LTE spectrum re-farming, ensuring better overall usage of resources.
