(Telecompaper) Sprint reached peak speeds of 275 Mbps in three-channel carrier aggregation lab tests using the LG G5, one of the first devices on the market to support the functionality. Sprint is independently testing three-channel carrier aggregation in its labs to evaluate overall performance, speed, and reliability as it prepares for LTE Plus network deployment. Carrier aggregation is an LTE-Advanced feature that bonds together bands of spectrum to create wider channels and produce more capacity and faster speeds on capable devices. Essentially it creates a wider lane that allows more data traffic to travel at higher rates.
