Promoting Interoperability in the 700 MHz Commercial Spectrum; Interoperability of Mobile User Equipment Across Paired Commercial Spectrum Blocks in the 700 MHz Band

In this document, the Commission seeks comment on whether the customers of Lower 700 MHz B and C Block licensees would experience harmful interference--and if so, to what degree--if the Lower 700 MHz band were interoperable. The Commission also explores the next steps should it find that interoperability would cause limited or no harmful interference to Lower 700 MHz B and C Block licensees, or that such interference can reasonably be mitigated through industry efforts and/or through modifications to the Commission's technical rules or other regulatory measures. The Commission initiates this proceeding to promote interoperability in the Lower 700 MHz band and to encourage the efficient use of spectrum.
