T-Mobile’s Chief Technology Officer, Neville Ray in his year-end highlights unveiled that almost 40% of calls made on the T-Mobile network are now on VoLTE. The jump from 33% just a month ago is supported by high VoLTE penetration and a significant portfolio of compatible devices, said T-Mobile.
As the third largest mobile operator in the US doubles its LTE footprint to reach 304 million Americans this year, it plans to focus its effort on 4G LTE network advancements such as 4x4 MIMO and 3-band carrier aggregation. The operator will also participate aggressively in the upcoming broadcast spectrum auction, while continuing to champion more innovation with LTE-Unlicensed (LTE-U). Meanwhile, T-Mobile played down on Verizon's announcements on 5G, saying that the industry standards for 5G are not yet established and that the technology is still in its infancy.
