§ 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
(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.
