You're in luck; these radios use only 5GHz for 'mesh'. Dave

traffic on my base:
 
2.4:
Channel Auto 9 11,-1 HT40
Transmit Power20 dBm (EIRP)
Tx Pkts/Bytes1,458,923 / 1.01 GB
Rx Pkts/Bytes467,285 / 70.4 MB
Tx Retry/Dropped46.2% / 0.2%
Rx Retry/Dropped0.0% / 0.0%
Ch. Util. (Busy/Rx/Tx)30% / 14% / 14%
 
5:
Channel Auto 38 36,+1 VHT40
Transmit Power24 dBm (EIRP)
Tx Pkts/Bytes146,775 / 111 MB
Rx Pkts/Bytes61,135 / 8.52 MB
Tx Retry/Dropped52.8% / 0.3%
Rx Retry/Dropped0.0% / 0.0%
Ch. Util. (Busy/Rx/Tx)9% / 4% / 4%
 
much less traffic on the 5 radio and the highest rate i get between towers is 150mbps, which is slower than draft N 300mbps - 5ghz ac wifi comms should have much higher comm speed

I'll repeat: these access points use only the 5GHz band to
'talk between each other', that is , to transfer data used for
WiFi access on both 2.4GHz and 5GHz bands.

 

But there's sopmething else going on that is far more important:
both bands ididcate retry rates of about 50%. That implies that
the link has very poor signal quality or levels. This setup is in failure.

Your only indication that helps explain is the 'rate i get between towers....'
These UniFi radios are not intended to be used as links between
'towers'--or any other long distances. For any kind of reliable performance,
they need good signals. They should be used within less than
100m of each other in open settings--much less than that if there
are obstructions.

UniFi uplink is meant to provide wireless service in limited situations
where no wiring is possible. If you need long links, consider AirMax radios. Dave
