The FCC’s Wireless Telecommunications Bureau sought comment today on a request (TRDaily, June 8) for a limited waiver filed by AT&T, Inc., to allow the use of power spectral density (PSD) measurements for cellular operations in seven Kansas cellular market areas (CMAs) until the FCC completes action in a proceeding in which it is considering modernizing its cellular licensing rules (TRDaily, Nov. 10, 2014). AT&T has proposed a power spectral density (PSD) limit of 250 watts/megahertz in non-rural areas and 500 watts/MHz in rural areas. It has filed similar waiver requests for other states.  Comments are due July 1 and replies July 13 in WT docket 15-130.
