I have 320 subscribers (on fibre) out of one of our PoPs, and the evening peak is around 1.6-1.8 Gbps these days. Oversubscribing 800 customers on a single 1 Gbps connection is going to result in an absolutely awful end user experience. Most WISPs make the mistake of failing to monitor airtime on their access points. With much of the low cost gear on the market the performance of a sector is going to be limited by the performance of the customer with the worst SNR. Newer gear that implements MU-MIMO significantly improves that since the access point can transmit to multiple subscribers at the same time. Have a look at some of the Cambium equipment. Other vendors have taken to implementing better QoS on the wireless phy side of things, but without MU-MIMO, it's just shuffling chairs on the deck of the titanic while the whole network sinks to the level of the guy with a bunch of trees in the fresnel zone of their 5 GHZ antenna.
