Various lower 700 MHz A Block licensees filed a study at the FCC Friday arguing that band class distinctions aren’t needed to protect some operations from interference and the agency should move forward on an interoperability mandate. MetroPCS, Vulcan Wireless,…

Continuum 700, Cavalier Wireless and King Street Wireless paid for the study. It was performed by V-COMM, a consulting firm. “Based upon our measurements and quantitative analyses, we conclude there is no meaningful performance differential between Band 12 and Band 17 devices that can reasonably be expected to result in Harmful Interference,” the report said (http://xrl.us/bngr3q). “The use of Band 12 devices should not impact B, or C, or B + C operators in any practical way. Our analyses are based upon worst-case thresholds of a 1 dB rise in noise floor, and therefore do not take into account typical industry engineering deployment practices which would further eliminate any potential interference concerns associated with interoperability. Therefore there is no reason, based upon empirical data, to select Band 17 operations over Band 12 operations.” Replies on the 700 MHz interoperability rulemaking notice are due Monday.
