SK Telecom Teams Up with Ericsson to Develop Uplink CoMP
Achieves more than 20 percent higher upload speed in coverage boundary areas and plans to apply the technology to all LTE devices in 2013

30(Fri), Nov, 2012

SK Telecom announced on Nov. 7 that it successfully demonstrated Uplink Cooperative Multi-Point (or Uplink CoMP), a technology that can significantly improve LTE data upload speeds in base station boundary areas. 
Signal strength is weakened in base station boundary areas, which leads to customer inconveniences caused by reduced data transmission speed. As more and more customers are uploading data from their devices (e.g. sending photos, videos taken with their mobile devices to social networking sites such as Facebook and Twitter, or uploading specific images/videos to the cloud for safe and long storage), SK Telecom decided to join hands with Ericsson, the world's largest maker of mobile network equipment by market share, to develop Uplink CoMP to enhance customer convenience by increasing data upload speeds in coverage boundary areas. 
SK Telecom and Ericsson started developing Uplink CoMP since last July and conducted a two-week technology demonstration from October 15, 2012. 
The demonstration showed that data upload speed (from device located in the coverage boundary area) between macro base stations increased by more than 20%. 
Uplink CoMP speeds up the data uploading rate/process in the coverage boundary areas by receiving handset/device signals through multiple base stations and then choosing the signal of the highest quality to be uploaded.
Moreover, in case a user conducts data download and upload at the same time, the uploading and downloading tasks will be handled separately by different base stations (and using a better quality base station for data uploads), thereby allowing users to actually experience the accelerated speed of data transmission.
