At 80MHz, you should see around 700Mbps aggregate
At 40MHz, you should see around 350Mbps aggregate
At 20MHz, you should see around 175Mbps aggregate
Let me give you some real world examples from my own, live, real customer network and from networks I’ve help to deploy over the past two years:
On a 20MHz channel, I can reliably do 65/65 for 11 clients on an AP but have seen 75/75 plenty of times. Depends on traffic
On a 40MHz channel, I can do around 170/170 on an AP with several clients.
On an 80MHz channel, I have seen clients doing 350/325 reliably.
Like Rudy said though, you’ll lose throughput for each additional client you add. I have an AP that has 31 clients, on an 80MHz channel, that reliably sees 150/100 for clients when doing a speed test. Now if everyone was running a speed test at the same time, it certainly wouldn’t look great at all.
Also here’s a chart with PHY rates per Modulation: http://ap.help.mimosa.co/access-point-faq-snr-mcs
With Mimosa being acquired by Airspan, all of our timetables have been and are still being reworked. I certainly don’t have any ETA on when true MU-MIMO will be available.
