Sec. 27.1255 Relocation Criteria for Broadband Radio Service Licensees in the
2150–2160/62 MHz band.
(a) An AWS licensee in the 2150–2160/62 MHz band, prior to initiating
operations from any base or fixed station that is co-channel to the
2150–2160/62 MHz band, must relocate any incumbent BRS system that is within
the line of sight of the AWS licensee's base or fixed station. For purposes
of this section, a determination of whether an AWS facility is within the
line of sight of a BRS system will be made as follows:
(1) For a BRS system using the 2150–2160/62 MHz band exclusively to provide
one-way transmissions to subscribers, the AWS licensee will determine
whether there is an unobstructed signal path (line of sight) to the
incumbent licensee's geographic service area (GSA), based on the following
criteria: use of 9.1 meters (30 feet) for the receiving antenna height, use
of the actual transmitting antenna height and terrain elevation, and
assumption of 4/3 Earth radius propagation conditions. Terrain elevation
data must be obtained from the U.S. Geological Survey (USGS) 3-second
database. All coordinates used in carrying out the required analysis shall
be based upon use of NAD–83.
(2) For all other BRS systems using the 2150–2160/62 MHz band, the AWS
licensee will determine whether there is an unobstructed signal path (line
of sight) to the incumbent licensee's receive station hub using the method
prescribed in “Methods for Predicting Interference from Response Station
Transmitters and to Response Station Hubs and for Supplying Data on Response
Station Systems. MM Docket 97–217,” in Amendment of Parts 1, 21 and 74 to
Enable Multipoint Distribution Service and Instructional Television Fixed
Service Licensees to Engage in Fixed Two-Way Transmissions, MM Docket No.
97–217, Report and Order on Further Reconsideration and Further Notice of
Proposed Rulemaking, 15 FCC Rcd 14566 at 14610, Appendix D.
(b) Any AWS licensee in the 2110–2180 MHz band that causes actual and
demonstrable interference to a BRS licensee in the 2150–2160/62 MHz band
must take steps to eliminate the harmful interference, up to and including
relocation of the BRS licensee, regardless of whether it would be required
to do so under paragraph (a), of this section.
