I wouldn’t dare to connect more than 50 stations to one AP.
I quote
YOU MUST HAVE NO MORE 62 CPE FOR THE LATENCY BE ACCEPTABLE FOR VOIP SERVICE…
I’ve no experience with NV2 so I’m curious, isn’t NV2 too jittery by nature for VoIP? or is it similar to Airmax jitter/latency?
Why you said a so precise number of cpe?
Is there a calculus to know approximative latency?
No calc, experience from WISP… 
Thanks, but what jitter do you think approximately will have 62 cpe on a nv2 bts?
on the peak hours 80/100ms
Thx
