Best smartphone with 2*2 MIMO WiFi support under 20k rs.

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 ?..

If your smartphone supports 5ghz wifi then go to WiFi settings and tap on your wifi name or SSID and reply me the connection speed or link speed that will be helpful to me if you don't know anything about channel width that I'm taking about ...

This year M30s/ m31 connected at 400mbps on 5ghz.
3 years old s8 connects at 800mbps. Kick u shamesung.

Thanks dude.... So samsung mid range smartphones do support channel width 80mhz on a 5ghz frequency that's good....I wonder if any relame phones supports 80mhz !!!
