Kyle: Take a look at www.Intellon.com . They detail a link to some of the problems associated with proximity of Bluetooth devices to 802.11 LAN specs. These are claimed to be potential interference problems related to hop frequency differences in the two spread spectrum systems.
There is also concern with the power line conducted control systems and the Continental Automated Building Associated attempted to address some of the issues related to compatibility during their conference held at the end of May. There are some 26 different standards all independantly developed which I'm sure is enough for a statistical study of the problem. There have been several papers on lack of EMC in hospitals - some originating from McGill University in Montreal. The main problem there seems to be lack of any emc equipment requirements ( although changing due to liability ) and the solution has been to isolate the areas containing the radio sensitive equipment. Tha Radio Advisory Board of Canada's EMC sub committee did address some concerns toward cable TV radiation and possible effects on some aircraft frequencies. With those problems largely overcome by regulating the cable operators , another issue has arisen and that could affect radio aids to navigation and it may have to do with radiation from home wiring above 2Mhz .. This is conceivable with ever increasing data rates and unshielded wiring. When I was chairman of the RABC EMC committee for a couple of years, there were many instances of life threatening incidences related to lack of EMC.
