Maximum number of devices on a wireless network?

It depends, on the hardware and to some extent also driver and firmware. The AP (and that goes down to the wireless hardware) needs to account for each connected client, reserve some (partially on-chip-) RAM for each connected STA and keep track of them (including buffering for power-saving clients), that limits the number of concurrently connected clients way before the theoretical limits. Then you also need to consider the mere availability of airtime slots, especially with older STAs in the m…

Maximum number of connected clients to a access point

The limit you hit will likely be a practical one, not a technical one. Eventually the devices start "talking over" each other causing re-transmits and the throughput to drop faster than you'd like. At some point, the bandwidth and latency get to be too high for your application. I'd guess it's in the dozens of devices somewhere for many applications. Probably a lot more if they aren't passing any data. Is it really a "mesh"? That means that the devices all connect to each other, not having to …
