Very interesting discussion from TechNation…normally I do not read all these magazines…but this caught my eye. Here is the link and excerpts. Again as I have said for years…why not use 802.11a/b/g…it is proven and it works…period.

“Over the years, multiple instances of interference have occurred when new transmitters were brought online or old transmitters were modified,” Hampton says. “Each of these occurrences was as bad as – if not worse than – the WFAA event, requiring the hospital and/or device vendor to implement expensive mitigation upgrades. The effect of the mitigation upgrades often resulted in telemetry systems with reduced or limited capacity.”
Hampton has a unique perspective. He believes that losing the effort to preserve channel 37 may be preferable to fighting the incursion into the channel.
“When you take into consideration the technical details I won’t bother with here, I believe it can be successfully argued that WMTS, as implemented, is actually less desirable than the original, unlicensed option originally provided.”
Our ultimate problem, in the long term, is that the technology for cardiac telemetry really hasn’t changed from the 1950s, when Spacelabs started designing this stuff for NASA. It is very spectrally inefficient. Now it’s robust in some respects, but in terms of interference, it’s not robust at all.” Hampton once saw a paper shredder interfere with WMTS communications and affect the system throughout the hospital.
“In some respects, losing this battle over [channel] 37 could be a benefit far greater than maintaining the status quo.”
