The chance that stray radio would imitate the WiFi signal and get interpreted as a command is practically zero. The RF interference could swamp WiFi and prevent the pendant from talking to the machine, but then again, stray low frequency EM could couple through the cabes and disable the wired pendant---it is not clear which effect is more serious and/or more difficult to protect against.. In fact, WiFi operates in a narrow band around 2.4GHz, so the wideband welding RF interference is probably delivering very little power into that band. Actually, I'd worry more about concentrated 2.4GHz interference, like, for instance, leakage from microwave owens---the famous 60-second WiFi dropouts. In any case, I'd say the wireless is worth trying. ------------------------------------------------------------------------------ Magic Quadrant for Content-Aware Data Loss Prevention Research study explores the data loss prevention market.
