I had some wireless connection problem with our automation machines at a convention (2000+ people). We control our machines wirelessly. Each of our machines has a Wi-Fi box, serves as an AP.

Then we use ipod/ipad/pda connect through wifi to control the machines.

Before the conferences all machine were able to connect wirelessly but once people start to come in we couldnt find a connection between our machine and the ipod/ipad/pda.

I understand that there has been known issues that at large conferences, between everyone's smartphone can tether, and laptops wireless cards.

There are just too many competing devices for the channels we have access to. Anyone have a solution for this?
