I have realigned the antennas and now we are getting roughly around -61 RSSI at both sides using a 20 MHz channel.
This is a very noisy environment where we have another service provider with several of their APs (5 GHz) installed in the same tower as us.
Also there are 4 other service providers (5 GHz) on a nearby tower about 100 meters from us with their own devices installed.
I have already chosen the best frequency I can find at the moment.
Using the Wireless Test Link, I am now getting around 75/75 mbps (Downlink / Uplink).
Doing some TCP test, I achieved an average about 40/45 mbps (Downlink /Uplink) with peaks about 50/60 mbps.
Why am I getting 25% less throughput than what is being reported in the Wireless Test Link tool?
Now, if I switch to a 40 MHz channel, Wireless Test Link tool averages 90/90 mbps and in a few cases peaked at 170/105 mbps.
Doing some TCP test, I achieved an average about 50/60 mbps (Downlink/Uplink) on the 40 Mhz channel with peaks about 65/75 mbps.
Again, the actual test is some 25% less than what is reported by the Wireless Test Link tool?
However, I observed that using a 40 MHz channel in this environment is susceptible with the connection link getting dropped every 5-10 minutes with the RSSI dropping from -62 dBm to -90 dBm every minute or so.
Will it really be possible in reality to achieve a 75/75 mbps throughput on a 20 MHz channel as reported by the Wireless Link Test tool once I start connecting users behind this backhaul at it’s current state?
Also will replacing the ePMP 1000 radio with an ePMP 2000 radio help?
Any suggestions will be appreciated.
