Make educated wireless router/AP upgrade decisions
> 650 → 390: MAC efficiency
> there are 'housekeeping' packets that MUST be sent at the SLOWEST possible modulationTrue, but it's actually the slowest supported/enabled modulation, which can be increased. In a crowded 2.4GHz environment (1Mbps min. modulation), raising it to 12Mbps or more can cut 50+% fluff (SSID, ARP, data broadcasts..) down to > 2166 → 1083: Client MIMO
> You must use the minimum MIMO common to both devicesMU-MIMO should enable the router to split its numerous MIMO channels to multiple devices with less MIMO channels. I have no idea whether it actually works.
