My company is demoing our network enabled products at big conferences. For this purpose, we would like to be able to set up a small WiFi network in our booth with a range of less than 10 meters. We will only be connecting the device that we are demoing and the iPad or PC running our demo software.

I understand that there are conferences that won't allow you to run your own WiFi equipment, but some fairly big ones do (e.g. IMTS, which we were just at).

I know that the AP should be encrypted and not broadcast its SSID, but are there additional equipment considerations to deal with the high level of RF noise in such an environment? Is there a particular technology that I should be looking at?
