DUBLIN--(BUSINESS WIRE)--Research and Markets (http://www.researchandmarkets.com/research/dzxs8s/signals_ahead_by) has announced the addition of the "Signals Ahead: By the Light of the Silvery Moon" report to their offering.
The combination of 2x20 MHz LTE, Category 4 devices, and Closed Loop MIMO with four transmit/receive antennas at the cell site delivers a number of noteworthy benefits. The headline peak data rate of 143.8 Mbps in the downlink (per TTI) and 46.93 Mbps in the uplink (per second) are noteworthy, but the real benefits are observed elsewhere.
Due to the presence of four receive antennas at the cell sites, we documented substantial benefits in the uplink performance, including much higher user data rates, far more efficient scheduling of network resources, and clear indications that the battery life of the mobile device was greatly enhanced. Generally, the benefits increased the further the mobile device was from the center of the cell, but the improvements in battery life were observed throughout a large portion of the cell. We also identified meaningful benefits in the downlink performance, again closer to the edge of the cell. And since all LTE mobile devices inherently support the 4x2 cell site configuration, the benefits of 4x2 are immediate and applicable to the entire installed base of mobile devices.
