In the "old days" before IFI, the old RC systems operated on the UHF band, the same band those little disposable radios (FRS) operate. Any type of radio freq. interference would do crazy things to the robots. The current IFI systems operate in the 900 mhz band, and go crazy if an 800 Mhz 5 watt portable is used next to one. At the risk of upsetting someone at IFI, they are not the best in terms of RF. Rumor has it that IFI maybe going to 2.4 Ghz. (As if there is not enough there already! Then look out you will not be able to run your WiFi. That last statement was a joke!)

One of the problems that concerned everyone at the championship event was the lack of channels available with 6 robots on the field at once. At one time it was thought that they would have to stager the matches to have everything work right.
