You ideally want an SNR of >25dB. Preferably 30dB.

Seems like most (rural) environments have a noise floor in the -95 to 
-100dBm range, so a -65 to -60 is ideal. If your noise floor is higher, 
adjust accordingly.


I think the point I was trying to make is that you don't want to turn it 
down to a value *lower* than -65dBm, or your modulation rates could 
suffer - even if you have a good noise floor.

The ideal signal range is around -60dBm, any stronger isn't necessary. 

The SMTRL will cause the subscriber to back of TX power until it meets 
the Target Receive Level. 

I would not recommend a Target Receive Level any lower than -65dBm, or 
your network will probably not work very well.

Re: [WISPA] Cambium ePMP2000 config question

2016-12-12 Thread Josh Luthman 
If you set it for say -80 it will lower the power if you're at -60 or -70
down to make it hit -80.

Now if you have a -130 noise floor then maybe that'll function, though
poorly, but you'll never ever hit the higher modulation rates that need -65
for example.

-60 is good, just leave it there...

I would also recommend requiring at least a -75dBm signal strength for 
all SM.

[WISPA] Cambium ePMP2000 config question

2016-12-12 Thread Art Stephens 
Just starting out using cambium ePMP gear. For configuring multiple APs on
a single tower the frequency reuse requires all APs on the same tower to
have their Subscriber Module Target Receive Levels set the same.

What are the pros and cons between SMTRL of -60 and say -80?

What should these be based on experience of those cambium users out there
that have successfully deployed these.

Thanks in advance...
