 37.  In-band Power Density Limits.  In the Notice, we proposed to limit the
power density of unlicensed Part 15 millimeter wave transmitters, except
those used in vehicle radar  systems, to 200 nW/cm2 at a distance of 3
meters from the antenna.  We indicated that this limit would accommodate the
needs of low-power, unlicensed users and would help ensure that unlicensed
millimeter wave devices comply with the relevant RF safety standards.  We
invited comment on the appropriateness of our proposed power density limit
and on alternative approaches that could be implemented to ensure that Part
15 millimeter wave technology devices are used safely.  One approach that we
suggested would be to approve devices with higher power density levels,
provided they have design features that preclude  excessive human exposure
to radio frequency signals.


 38.  The commenting parties generally request that we permit higher power
density levels than were proposed in the Notice.  HP and mmWAG both submit
that the power density limit should be raised to 9
