Hi,
I’m trying to configure 8-10 clients using RB-SXT and RB-711 connecting to OmniTik U-5HnD.
Config is as follows (on all devices):
(Wireless) > Band> : 5GHz-only-N
(Wireless) > Channel Width> : 20/40MHz HT Above
(Wireless) > Frequency> : 5180 MHz
(Wireless) > Wireless Protocol> : nv2
(Wireless) > Security Profile> : default
(Wireless) > Rate Selection> : advanced
(Wireless) > Rate> : default
(Advanced) > Adaptive Noise Immunity> : ap and client mode
(Advanced) > Preamble Mode> : both
(HT) > HT Tx Chains> : chain0, chain1 (RB711: chain0)
(HT) > HT Rx Chains> : chain0, chain1 (RB711: chain0)
(HT) > HT AMSDU Limit> : 8192
(HT) > HT AMSDU Threshold> : 8192
(HT) > HT Guard Interval> : long
(HT) > HT AMPDU Priorities> : 0,1,2,3,4,5,6,7
(NV2) > TDMA Period Size> : 2
All RB’s are using ROS v5.14. Frequency is clear (I tried changing it too).
The problems I’m facing:
#1: CCQ’s are strange. Why is Rx CCQ always lower then Tx?
Client1 - 99/86 %, Client2 - 63/66 %, Client3 - 100/58 %, Client4 - 93/61 %, Client5 - 63/53 %, Client6 - 94/34 %
#2: Clients that have RB-SXT have wierd Rx/Tx signal levels. Eg.:
Tx/Rx Signal Strength: -67/-62 dBm
Tx/Rx Signal Strength Ch0: -68/-81 dBm
Tx/Rx Signal Strength Ch1: -83/-62 dBm
Signal to Noise: 56 dB
#3: With RB-SXT clients there’s no difference between only Chain0 being on (HT Tx & HT Rx) and both Chain0 and Chain1 being on. Throughput is the same. Why?
#4: With the above configuration I can’t get more then 70 Mbps UDP and 40 Mbps TCP throughput. Why is that? Is something wrong with the config?
NOTE:
All clients have LOS with no obstructions.
All clients have signal levels between -61 and -68.
I conducted bandwith tests between OmniTik and SM’s only, not through the Ethernet.
Results are the same regardless of number of SM’s connected (1-8).
Thank you!
