4×4 MIMO on Galaxy Note 7 is a first


UpdateThis article has been updated to reflect information about 4×4 MIMO technology in relation to the Snapdragon 820 given to us from Qualcomm.

The Snapdragon 820 can support 4×4 cellular multiple input-multiple output, but you’d be struck to find a phone manufacturer willing to stuff four cellular antennas into their device. Well, the Galaxy Note 7 can claim to be the first phone that utilizes 4×4 MIMO.

Ideally, 4×4 MIMO would handle networks that could use four physical streams of data. T-Mobile does not have such an infrastructure active yet, so, according to folks on the T-Mobile subreddit, it has decided to map two physical streams to towers with four-antenna MIMO support.

The short result? Better possible reception and faster speeds. T-Mobile is field testing 4×4 MIMO and will be able to activate the feature in an OTA update for the Note 7.

All Snapdragon 820-equipped phones have Qualcomm’s X12 LTE modem and thus has 4×4 MIMO support, but it seems that Samsung wanted to stuff the antennas into its Note 7 as fast as it could.

And who said that the Note 7 wasn’t innovative?
