South Korea's SK Telecom says that it achieved the world's first commercialization of Uplink CoMP (Uplink Cooperative Multi Point) a technology that can significantly enhance mobile data upload speed on the LTE network.
In an area covered by multiple base stations, Uplink CoMP directs that signals from mobile devices are received by not one but multiple base stations, and combines these signals to increase signal strength.
The tests were carried out in cooperation with NSN (Nokia Solutions and Network).
SK Telecom and NSN said that, once applied with the technology, the mobile data upload speeds increased by an average of 20 percent in coverage boundaries.
Moreover, as Uplink CoMP is a technology that is applied to base stations, no upgrade is required for LTE devices. SK Telecom said that it plans to apply the technology to all its LTE base stations within the end of this year.
The company expects Uplink CoMP to significantly increase performance for social media users who are uploading photos and other media content.
Park Jin-hyo, Senior Vice President and Head of Network Technology R&D Center at SK Telecom said, "SK Telecom is pleased to announce the world's first commercialization of Uplink CoMP, which will dramatically increase the data upload speeds for our LTE customers. Continuous efforts will be made to develop and apply innovative network technologies like Uplink CoMP to provide our customers with greater convenience and differentiated value."
