8x8 MUMIMO at 40MHz with 256QAM gives us 4 end users at ~300Mbps physical rate
you don’t need 8x8 MUMIMO to achieve that.
40MHz/256QAM (8x) has been doing 389Mbps physical rate 10 years ago with --ANY-- 802.11ac device.
The real transfer (tcp, big files) is almost always channel size times modulation rate, so 40MHz times 8x multiplier in this case would be around 320Mbit/s (320MBps) REAL throughput. Of course, that throughput is in interference free environment etc (but interference doesn’t affect datarates at all, almost).
Look here : Ask about Force 400 30 db antenna
Force 400 devices which are not 8x8 and : “My recommendation would be to get the signals on all chains into the 50’s and then you’ll be able to hit the DS11 modulations, and it will SCREAM. We get about 465 Mbit in a 40Mhz wide channel with ours – but the key is to get the signals and SNR were they need to be.”
they have 465Mbit in the 40MHz channel compared to 389Mbit mentioned by me because Force400 are 802.11ax devices - I was talking about 802.11ac. DECADE old technology.
With superhyper 8x8 16x16 MUMIMO devices, I would expect REAL throughput to be around 800 Mbit/s for multiple clients in parallel…
