Dealing with wireless interference from cellphones

[pyroslev]

1400 people with who knows how many on wifi could give you headaches. With FTC, we make announcements periodically asking people to turn of Wi-Fi on phones.

Did you ask the venue to turn off unsecured wireless networks or disable internet access to them?

And it's possible there was a lot of non-WiFi related interference. That can have you beating your head against a wall for hours.

We've had this exact scenario happen to us twice at graduation and I don't have a solution yet. Robot tested in the venue with no problems whatsoever, excellent communication over 150 ft range. As soon as 800 or so people show up, we're dropping packets like crazy and can barely even operate the thing, even at closer (<50ft) range. Operating direct from the Classmate PC.
