the band with Wi-Fi and other unlicensed. “Given the significant body loss that affects connectivity between body-worn devices, 14 dBm radiated power is the minimum level of power that will reliably enable AR/VR applications” but the devices don’t have to “typically or constantly transmit at these power levels,” said the filing in docket 17-183. Apple, Broadcom, Cisco, Facebook, Google, Hewlett Packard Enterprise, Intel, Microsoft, NXP Semiconductors, Qualcomm and Ruckus Networks were represented. Meanwhile, cable Interests are pushing for low-power indoor (LPI) Wi-Fi use in the band. Comcast, Charter Communications and Cable Labs told OET it isn't a threat to fixed service incumbents in the band, and data from 500,000 Wi-Fi access points used in simulations helped prove that, per another posting Monday. Comcast in meetings with aides to Chairman Ajit Pai and Commissioners Brendan Carr and Geoffrey Starks urged allowing LPI use throughout the band without the need for automated frequency coordination.
