I took a look at the AusCert posting for this problem. It appears to be nothing more than setting a card to send packets continuously, thus setting everyone's carrier sense high and blocking the channel. The press release maintains that the transmitter 'cannot be located' but this is a mystery to me: since the transmitter must send continuously to cause a problem, it ought to be quite simple to locate the offending node using raw signal strength or (preferably) a directional antenna and a spectrum analyzer. For large organizations that are likely to own the space around their network, the offending node would be on their property and could be shut down or asked to leave. In any case it certainly isn't news: FCC part 15, "unlicensed devices must accept interference". Daniel M.
