Sprint showed off its Gigabit LTE network at an even in New Orleans. It’s nothing short of impressive, but what has us asking questions is the mysterious Motorola prototype handset Sprint used to demonstrate its Gigabit LTE speeds.
It’s a “prototype” device, yes, but Sprint let the word out that Motorola would be one of the first manufacturers out (at least on its network) with the hardware necessary for obtaining Gigabit LTE speeds.
On top of that, Motorola’s Shakil Barkat — CVP of Global Product Development — said that the company is working on a device with said hardware that would be released later this year. The device Sprint demonstrated its Gigabit LTE network could be that handset.
We don’t know much beyond that, although Barkat did confirm it would run on the Snapdragon 835 platform.
On the other hand, Sprint’s Gigabit LTE network is nothing short of impressive. During a high-traffic NBA game, the phone was able to achieve an impressive 613MBp/s, but a measly 8MBp/s in upload speeds. Sprint is able to achieve these speeds thanks to 4×4 MIMO, 256-QAM, and three-carrier aggregation. To achieve these speeds, the handset needs to not only support 256-QAM and three-carrier aggregation, but it also has to fit four MIMO antennas inside the phone, which is a difficult task.
Ryan Sullivant — Sprint’s VP of Product Engineering & Development — confirmed that this Motorola device would be the first of “many” Gigabit LTE-ready handsets we see this year.
