Broadcasters Warn FCC Against Dropping Coexistence Rules for White Spaces

摘要

The FCC should be wary of dropping from a requirement that devices using the TV white nspaces be able detect other use of the spectrum and that they consult a database of TV nchannels occupied in the market, the NAB and the Association for Maximum Service nTelevision said in a meeting with representatives of the commission's Office of Engineering nand Technology. Geolocation and "database proposals that omit sensing capability would nnot provide sufficient protection for wireless microphones used for on-the-spot local news and nemergency coverage," the groups said in a filing. They said they also made technical npoints about "the need for minimum bandwidth requirements, power density rules, and power nlevels of devices operating on adjacent channels."
