I'm looking for a smartphone with 2*2 MIMO support under 20k rs.. I can't find anywhere .The smartphone company just mentions the 802.11 standards but they are not mentioning how many spatial streams can it support and how much channel width can it support on 2.4ghz and 5ghz frequency... Most mid range smartphones support 5GHz but can they support channel width upto 80mhz ? If anyone know please answer .. Smartphones except poco m2 pro and Redmi note 9 pro are there any other phones that they support 2*2 MIMO and channel width upto 80mhz ?..
