Sprint Retires 'Spark' and Launches 'LTE Plus'
Sprint is rebranding its LTE 4G network in an effort to call attention to the technology involved in making the network tick. Sprint LTE Plus replaces the Sprint Spark name for the company's tri-band LTE network, which uses 800MHz, 1.9GHz, and 2.5GHz. Sprint has focused on optimizing the performance of cell sites, as well as on improving the underlying network tech by taking advantage of carrier aggregation and beamforming. Carrier aggregation is the binding of two or more channels to act as one to increase capacity. Beamforming involves focusing wireless signals, particularly in the 2.5GHz band, in order to better reach handsets. Sprint claims these techniques have doubled network capacity and speeds (peaks greater than 100Mbps), increased the range of 2.5GHz spectrum, and improved reliability across all three spectrum bands. Right now, Sprint says 77 markets have access to these network improvements. More importantly, 13 of Sprint's devices, including the iPhone 6s, Galaxy S6, and One A9, support the new wireless technologies. Sprint said it plans to expand Sprint LTE Plus to more markets and more devices over time. The company will also continue to improve its network technology, and is looking to use 3-, 4-, and 5-channel carrier aggregation, advanced beamforming, and higher order MIMO down the road.
Sprint Flips On 3-Channel Carrier Aggregation for iPhones and Galaxies
Sprint gave some of its high-end smartphones a speed boost this week. The company added 3-channel carrier aggregation to the Apple iPhone 7 and 7 Plus, Samsung Galaxy S7 and S7 edge, and the LG V20 and G5.
Sprint Doubles LTE Plus Footprint
Sprint today said it has doubled the availability of its LTE Plus coverage from 77 markets in November to more than 150 markets today. Some of the new markets include Boulder, Colo., West Palm Beach, Fla., Cleveland, Ohio, and Syracuse, N.Y.
Sprint's 3-Channel LTE Reaches 295Mbps
Sprint today said it has achieved peak download speeds of 295Mbps using three-channel carrier aggregation on the HTC 10 smartphone. Carrier aggregation pairs together multiple segments of spectrum to improve speed and capacity.
Sprint Claims to Reach 300Mbps Downloads with Galaxy S7
Sprint today said it was able to achieve peak LTE speeds reaching 300Mbps on the downlink with the Samsung Galaxy S7. The phone, says Sprint, is among the first to support three-channel carrier aggregation, a feature in LTE-Advanced.
AT&T Stepping Up Three-Channel Carrier Aggregation
AT&T today confirmed to Fierce Wireless that, like its competitors, it is deploying three-channel carrier aggregation on its LTE 4G network. "We're currently in the process of deploying three-way carrier aggregation on our network," said AT&T spokesman Steven Schwadron in a statement given to Fierce.
