We have a mix of clients getting assigned by gateway router either 7 or a 30Mbps queue.
After we've done the upgrade on both CPE's as AP we are testing the network by running a bandwidth test to at least 3 clients simultaneously.
In NV2 it is a rare event that client reaches its maximum assigned speed and the total throughput over the AP sort of 'hangs' around 40-60Mbps with the other clients testing.
The moment we'd swap to 802.11 we see speeds to client climbing up and also the throughput over the AP goes up.
When testing a single client they almost guaranteed get the maximum assigned 30Mbps (tcp traffic) and the AP's throughput sometimes more then doubles.... (not always double though, but always some improvement)
All these AP's are in a very congested spectrum environment where it is always a struggling to find some relative 'free' radio band.
we have one AP though that is a NetMetal connected to a 18dBi RF elements dome pointing towards a region where no other towers are penetrating with their signals and here we found one AP that indeed performs better in NV2!
Still I have problems to get over 100Mbps over the AP and only see some short live 'peaks' reaching 125Mbps in a 40Mhz wide channel. This unit only has 12 CPE's.
My conclusion is a repeat of some ROS versions ago; 802.11 (either 'n' or 'ac') outperforms NV2 in P2MP networks by some 10 to 100%!
We also learned some setting of one AP can never be copied into another. It always has to be tested but so far 802.11 with RTS/CTS is a very good protocol and in 'ac' we can even work with 80Mhz channel that are partially overlapping other channels due its standard (IEEE) build in interference avoiding system.
