FCC Proposes to Allocate 20 MHz of Spectrum in 413-456 MHz Band For Implanted Neuromuscular Devices
The FCC has released a Notice of Proposed Rulemaking (NPRM - ET Docket 09-36) seeking comment on a proposal to allocate 20 MHz of spectrum in the 413-457 MHz band for use by wireless medical devices that could be implanted into the human body and used to restore sensation and mobility to paralyzed limbs and organs. The devices would act as a wireless medical micro-power network (MMN) within the patient. Among the conditions that could be treatable using MMNs include polio, ALS (Lou Gehrig's disease), cerebral palsy, and spinal cord injuries.
The 400 MHz band is targeted because it is optimal for RF propagation through body tissue. The devices would require at least 5 MHz of bandwidth to function and would operate on a low power, secondary non- interference basis. Twenty MHz of spectrum in four band segments are proposed so that the device would have four options in case one band segment was already in use in a given area. The NPRM seeks comment on the feasibility of four different band segments:
* 413-419 MHz
* 426-432 MHz
* 438-444 MHz
* 451-457 MHz
Comment is also sought on:
* Potential for interference between MMNs and incumbent users
* Service rules (licensed or unlicensed, definitions, permissible communications, eligibility, etc.)
* Technical rules (power limitations, bandwidth, frequency stability, channelization, antenna locations, etc.)

Hi All,
From another group I read that the maximum power radiated outside the body
will be around -30 to -40dBm, so not much chance of these systems being a problem to us.
But of course if they expect "protection" from our signals....

This statement from the NPRM seems to indicatate that we might not see use of this out in the open vs. a permanant implant. "The Notice proposes to limit MMN operations to use only by persons for diagnostic and therapeutic purposes, and only to the extent provided under the direction of authorized health care professionals."
