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.)
