risk of harmful interference to [fixed service] licensees through an antenna elevation mask for 6 GHz low-power indoor RLAN devices that would impose special restrictions on the maximum EIRP of an RLAN device in the horizontal direction (i.e., within a certain angular distance above and below zero degrees elevation),” HPE filed, posted Friday in docket 18-295. “Virtually all enterprise RLAN devices already direct most of their energy downwards, with maximum gain generally at or below -30 degrees elevation,” the company said: “However, devices employing an elevation mask in the horizontal plane would further reduce the already small probability that an RLAN device could be designed to radiate more energy than necessary toward the horizon.”
