Technology. The FCC proposed in an April 2020 Further NPRM to allow VLP devices to operate in the band indoors without automated frequency control (see 2306230046). “In order to reduce the already insignificant risk of harmful interference even further … we discussed that the Commission could take two further steps,” said a filing posted Wednesday in docket 18-295. The FCC could create a transmit power control (TPC) rule for VLP equipment “that contains a specific and measurable power-reduction mandate,” the filing said: “Such a rule could state that TPC shall, on average, reduce the PSD [power spectral density] of the VLP device by 3 dB, compared to the maximum permitted PSD of VLP devices. The Commission would then permit VLP equipment makers to demonstrate during the FCC device certification process that a particular VLP device complies with this rule in order to receive authorization to operate at the maximum permitted” PSD. The FCC could also prohibit VLP devices from operating as part of a fixed outdoor installation, Apple and Broadcom said: “By doing so, the Commission would ensure that all VLP operations would be itinerant, not operating at any one set place and in any one set orientation to a FS receiver.”
