The comments filed in response to the NPRM provide insufficient technical information on whether the use of cellular phones onboard aircraft may cause harmful interference to terrestrial networks. Further, because airlines, manufacturers, and wireless providers are still researching the use of cell phones and other PEDs onboard aircraft, the FCC found that it would be premature to seek further comment at this juncture. Therefore, the FCC determined that its proceeding on this issue should be terminated at this time. It may, however, reconsider this issue at a later time if appropriate technical data is available.
