As I’m sure you know coverage isn’t going to be the problem, it’s the sheer number and density of users. Predominately for these high density deployments you would look to use sectorised antennas to create ‘zones’ and try to limit the number of users connecting to each AP which in turn will ensure performance.
Estimating how many APs will be required for the high density design. How many clients can I connect to a single AP? This is the single most common question in Wi-Fi. The unqualified and unsatisfying answer is “It depends.” But it’s also very true. The answer to this question will change dramatically depending on:
· Key performance metrics (applications, bandwidth, latency)
· Client capability and estimated number of devices per AP
· Allowable AP mounting locations
· Physical density of people
AP hardware selection Impact of Performance Requirements, the required per-client performance characteristics will heavily influence the number of APs required. This number allows the maximum capacity of a single AP to be estimated. Client Capability How quickly a device can get on and off the air helps determine how many clients can be supported given the required performance metrics. This reduces latency and increases the amount of data that can be sent at any given time. The maximum transmission speed of a wireless device is typically listed as a reference but the actual throughput that can be achieved will always be less.
