Sprint demonstrates 295Mbps on Galaxy S7
Sprint uses three-carrier aggregation on LTE-Advanced to push download speeds to almost 300Mbps
US operator Sprint has expanded the range of mobile devices capable of working at nearly 300Mbps to include the HTC 10, using three-carrier aggregation.
The company says it has used the LTE-Advanced technique to achieve peak speeds of 295Mbps in lab tests. In March Sprint said that it had achieved 300Mbps in tests with the Samsung Galaxy S7.
Now the company says it offers five devices that are capable of operating on three-carrier aggregation services – the HTC 10, HTC 9, LG G5, Samsung Galaxy S7 and Samsung Galaxy S7 Edge.
Sprint already offers two-channel aggregation in 237 markets across the US, offering speeds of more than 100Mbps, under the LTE Plus brand.
“LTE Plus uses some of the most advanced technologies in wireless such as carrier aggregation and it’s a key part of our densification and optimisation strategy,” said Günther Ottendorfer, Sprint’s chief operating officer for technology.
“With LTE Plus we’ll keep delivering the best mobile services for our customers with higher throughput and capacity using very cost-efficient solutions.”
Adding a third carrier to the service will mean the company used 60MHz of spectrum to deliver data at more than 200Mbps on compatible devices. They will be enabled to take advantage of the service after a software download.
Sprint did not announce the three bands in use, except to say that the service would be delivered via its 2500MHz cell sites. The other two bands are believed to be 800 and 1900MHz.
Rival operator T-Mobile US was revealed to be trying out three-carrier aggregation in June, using spectrum in the 700, 900 and 2100MHz bands on a Samsung Galaxy Note 5 phone.
