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
