T-Mobile patent points to efforts to improve video call quality
August 27, 2015
A patent filing from T-Mobile US (NYSE:TMUS) shows that the nation's third-largest wireless carrier is working to make video calls over its network more efficient. Such an effort by the carrier is not surprising considering video chews up dramatically more bandwidth than most other types of communication.
T-Mobile's patent, initially filed in 2012 and recently made available, outlines "techniques to optimize video-call communications." The carrier also said in the filing that "the link quality capability of a wireless video-call session and the requirements of the video-call session are determined [in the patent]. The link quality capability determination is based at least on measurements through the entire communications chain, including user, client device, operating system, application, air interface, cell sector and backhaul parameters."
