I am in the middle of designing a high density WiFi solution for an auditorium that seats 3,200 people. I am using the 3702P access point with the AIR-ANT2513P4M-N antenna.
The antennae will be mounted on ceilings and catwalks with the antennae pointing down towards the ground, essentially a "coverage from above" scenario. The antennae will be mounted approximately 30 feet above the floor and are listed as having a "30x30" azimuth/elevation plane.
My question to those who might know is this:
Is there a formula or matrix or template that can be used to determine the "coverage area" on the floor? Since the AP's/antennae essentially are shooting the signal at angles, the coverage area logically grows bigger the further away from the antenna the client radio is positioned.
I understand all the different nuances of power adjustment/SNR/number of devices/traffic types, etc. But since the coverage is essentially "painting" the ground, my goal is to try to minimize channel/signal overlap (especially in the 2.4 gHz spectrum). So basically, I'm trying to understand how to calculate the coverage area at different distances from a single antenna/AP combo in order to position the neighboring antennae at such angles as to help minimize the overlap. I'm planning on budgeting approximately 60 connections per AP unless I simply find there's no way to minimize/mitigate the channel/signal overlap between coverage areas.
Thanks in advance for any help.
