Why wait for 5G? T-Mobile's CTO is now claiming the operator will deliver near-gigabit downloads over its 4G LTE network.
"Just last week we reached nearly 1 Gbps (979 Mbps) on our LTE network in our lab thanks to a combination of three carrier aggregation, 4x4 MIMO and 256 QAM (and an unreleased handset). This is the fastest speed possible on a mobile device today and T-Mobile will absolutely be first to Gigabit speeds!" wrote T-Mobile US Inc. 's CTO Neville Ray in a blog Thursday.
Three-carrier aggregation refers to the use of three radio channels bonded together to increase mobile speed and capacity. 4X4 MIMO is a multiple input and output antenna array, while 256-quadrature amplitude modulation (QAM) is the most efficient signal modulation scheme currently available for boosting throughput on available mobile spectrum.

Oh, and the secret handset is probably from Samsung Corp. .
"Ever advancing LTE will continue be the technology that powers wireless into the next decade – and there will be major advancements to come, well beyond 'just' Gigabit speeds," Ray notes.
While the CTO says he is "excited" about 5G he also notes: "It will take several more years for 5G to be meaningful for mobile."
