I think in the real world, the things are more complicated then what is written on data-sheets of course.
So in a even more crowded spectrums out there, is always more important to have good tools to fight against interference.
The most important for me is to have a live spectrum analisys or an automatic system to change better frequency when some conditions will be verifyed looking for past spectrum.
Many vendors like Ubiquity, Mimosa and others support those features. More useful feature is store past spectrum in the Cloud so you can look for difference during time.
I want to show an example: 1 PTP 800 meters long 390/390 Mbps full duplex available bandwidth on 80 Mhz. One day I receive a call from my customer told me the network is really slow. The first thing I was done, is looking to Cloud to see difference in Spectrum comparing actual moment to some hours before. Well, this simple things had show me someone choose a frequency too near to mine. So I simply moved AP radio some Mhz away to restore perfect signal and throughput. More important thing is during that change I don't loose the link !!!!
This it needed only 15 minutes, from my Android Smartphone. No PC. No tablet. Nothing.
This is a too much important too to survive in Wisp life today.
Today with Cambium it is simply a NIGHTMARE to use it:
1) change to spectrum analisys mode
3) download jar package and start
4) select oly 100 Mhz per time to look into (really bad choose)
5) close tool
6) change to SM wireless mode first, reboot
7) hoping the SM don't remain into Spectrum Analisys mode
All this things, could be done only during night hours hoping no any customers use the network. To do a decent scan you surely need almost 20-30 minutes.
It is simply IMPOSSIBLE due to daily WISP activities.
