T-Mobile released a video today showing an unreleased and unknown phone running over the carrier's LTE network at a speed of nearly 1Gbps. According to the carrier's CTO Neville Ray, T-Mobile was able to achieve this speed using three carrier aggregation, 4 x 4 MIMO (multiple input, multiple output) and 256 QAM.MIMO increases data speed by adding more connections between a cell site and a customer's phone. QAM increases the number of bits per transmission, increasing data speeds. Carrier aggregation allows carriers to join together multiple spectrum channels to increase the size of the ...
