We've set a PtMP implementation with a centralized AP (433UAH) and 9 SXT clients connected on APs sector antenna.
Antenna is dual polarized (HV). Below you may find a screenshot with distances and respective SNR values.
The majority of the SXTs are located at 15km distance from sector antenna.
Each individual SXT at 15km distance gains 20mbps using bandwith test tool.
However the problem is when simultaneous traffic come from parallel SXT sessions, AP wireless interface (wlan2) cannot serve more than 10-12 mbps in total.... Very, very dissapointing....
Protocol used is NV2 and N-only mode (superchannel enabled) with latest ros v5.5 on ap and sxt clients. AP wlan2 hw is R52Hn.
No other 5Ghz networks exist on the area for potential interferance issues.
Is this something normal???
Which is the expected data rate thoughput on such implementations?
What we also noticed is that clients with weaker signal get very frequent disconnections whenever total data thoughput is high i.e. running bandwith test tool (control frame timeout log indication).
Please for your help and comments.
