I collected many of these as they were used by Cisco at the Cisco Live Europe event in London end of Jan 2013 and started lokking at it.
The application for frequency usage is here: http://stevencrowley.com/2012/...

There is a second chip on the device with the numbers F980, BR7Z, 234+ the package is a 20 pin package with (starting from pin 1) 5 pins, 6 pins, 5 pins and 4 pins on each side. The crystal on the one I have is 30.0MHz.

Its a signal centered on 869.5 mhz. I think someone who is RF savvy (ham hacker perhaps?) needs to desperately either get some RF recieving gear in the vicinity of the next concert that hosts one of these or someone needs to bring an old one of these bands along and do a pin trace of the RF chip.

I seriously seriously doubt that the transmitter the company is using is using any sort of encryption, once we know the schema of the signals they should be pretty easy to duplicate.
