Proposed rule.


The Commission seeks comment on the Land Mobile Communication Counsel's (LMCC) proposed interference contours for interstitial channels, submitted on May 26, 2015, during the reply comments stage in the pending rule making proceeding. This action is necessary because the Commission desires the benefit of public comment on the proposed interference contours which were not advanced by LMCC until the reply stage of the Interstitial NPRM. The intended effect of this action is to give interested parties a sufficient opportunity to comment on LMCC's May 26, 2015 proposed interference contours.


Submit comments on or before September 8, 2015.

In the Notice of Proposed Rulemaking (NPRM) in WP Docket No. 15-32, the Commission initiated a new proceeding to seek comment on proposals to amend the Commission's rules governing 800 MHz Mid-Band operations (809-817 MHz/854-862 MHz) 80 FR 15723 (Mar. 25, 2015). The Commission sought comment on appropriate interference protection criteria for interstitial channels, including a proposal from the Land Mobile Communications Council (LMCC) to amend the rules to adopt new “Interstitial 800 MHz Coordination Procedures.” On May 26, 2015, the LMCC filed its reply comments in the pending rule making proceeding. Therein, LMCC advanced proposed interference contours to apply when stations of various modulation types are operated on interstitial channels (12.5 kHz spacing) adjacent to “standard” (25 kHz spacing) stations operating with various modulation types. In order to develop a full and complete record, the Wireless Telecommunications Bureau and the Public Safety and Homeland Security Bureau issue this public notice seeking comment on LMCC's proposed interference contours. The Commission will accept comments on the LMCC proposed interference contours on or before September 8, 2015.
