I asked this question on StackOverflow and was directed over here, so I'd appreciate any advice.
I'm deploying a smartphone application as part of a live music performance that depends on receiving UDP broadcast packets from a wireless access point. I'm guessing that between 20 and 50 clients will be connected at any one time. I'm aware that a maximum of 20 clients per access point is advised, but as the UDP broadcast packets are ground through the LAN, how would I be able to link multiple APs together?
I'm looking for recommendations on a suitable AP for this. The actual data transmission rates are very low - only a few kB/s - as I'm just sending small messages to the smartphone apps, and there will be no WAN internet connection. I tried it with a few connected peers on an adhoc wireless connection without any problems, but ran into dropped packet issues on an old WRT54G running ddwrt, though it's in pretty rough shape.
What's the best way to do this? I suppose I could limit concurrent wireless connections to 20 clients... but more would be nice.
EDIT: I should also say that it's purely one-way communication; the smartphone application is only receiving broadcast packets, not sending anything.
