The Aerospace and Flight Test Radio Coordinating Council (AFTRCC) “strongly supports” an FCC proposal to allocate spectrum for Aeronautical Mobile Telemetry in the 5091-5150 MHz band, the group said in comments filed at the FCC. “The 5091-5150 MHz allocation proposal…

is in response to U.S. recognition that the extraordinary growth in telemetry data rates places serious constraints on existing allocations for flight test telemetry,” AFTRCC said (http://bit.ly/YzLVVC). “The strained capacity of the existing bands adversely affects aviation development and, if the situation were left untreated, the productivity and global competitiveness of U.S. aerospace manufacturers could be undermined.” AFTRCC also supported the deletion of the non-federal Aeronautical Mobile Telemetry allocation at 2310-2320 MHz, as also proposed by the commission. “It is of limited utility due to its secondary status which precludes its use for safety-related applications,” the group said. “Given that and the impending development of LTE systems in that band, AFTRCC would urge that the allocation be removed. However, recognizing that there are a few (three) licensees which still hold authorizations for this spectrum, AFTRCC would urge that a reasonable period of time be allowed for a phase-out of the allocation, either five years or the end of each respective licensee’s current license, whichever is longer.” Boeing supported AFTRCC’s comments, with an additional caveat. “Because of the sensitivity of flight test receive equipment, and the critical nature of flight test communications, Boeing would urge the FAA to coordinate any implementation of WiMax at airports with operators of flight test receivers that could suffer harmful interference from co-channel operations in the 5091-5150 MHz band,” Boeing said (http://bit.ly/YEzpYZ).
