FCC OKs On-Body Medical Networks

itwbennett writes "On Wednesday the FCC approved the use of medical micropower networks (MMNs) in four blocks of the 400MHz spectrum band despite opposition from broadcast engineers who say they are concerned about interference. MMNs can be used to bypass areas of the nervous system that have been impaired by strokes or spinal cord or brain injuries."

Actually, the real concern was interference from Amateur Radio signals. The frequency range that these devices plan to use is in the 440 - 450 MHz range... which is right where a bunch of the little hand held ham radio units operate. The ARRL (National Amateur Radio Association) was the biggest group against the proposed usage, and the FCC only permitted the use with the prevision that it was Secondary to the existing licensees (HAMs). In other words, the medical devices cannot interfere with the radios, and they have to be able to live with any signals produced by radios. Here [arrl.org] is an in depth article regarding the FCC grant.
