FCC AMENDS PRIVATE OPERATIONAL FIXED MICROWAVE SERVICE RULES TO FOSTER RADIO LANS 8 February 1990 PR Docket 88-191 The Federal Communications Commission has amended its rules governing the use of the 10.6 and 18 GHz bands by licensees in the Private Operational Fixed Microwave Service (POFMS). Among the changes intended to promote more use of these channels, the FCC decided to allow 18 GHz licensees to operate multiple low-power transmitters (radio LANs), instead of one high-power transmitter serving a number of remote stations, within their defined coverage areas; removed the "digital only" restriction from the 10.6 and 18 GHz bands (however, "video entertainment" can't be distributed in the 18 GHz channels); changed the application procedure so licenses can be issued on a "first come, first served" basis; set a 35 mile separation standard for co-channel systems (instead of 50 miles as before); and eliminated the need for detailed interference analyses as part of most POFMS applications. Under the new rules, applicants must notify the operators of nearby systems assigned to the adjacent channels and prepare an interference analysis only if one of them objects to the proposed facility. Under the new rules for radio LANs, a licensee would specify a coordinate as the geographic center of the proposed network, with the right to put multiple low-power devices within a certain radius from that reference point without the need for additional coordination. The 35-mile standard would apply to the central coordinates of radio LANs operating in the same channel. According to an FCC news release, "the 35 miles separation standard would provide an adequate service area of approximately 12 miles and will better accommodate new station entry." During the question period, FCC Commissioner Marshall asked Ralph Haller, chief of the Private Radio Bureau, if he expected a lot of people to apply for 18 GHz radio LAN licenses. "I certainly do expect that the band may be widely used for that, and there has been some expression of interest already in that kind of operation," he replied. News media contact: Patricia A.
