Long-Term Evolution Uplink Impacts on Aeronautical Mobile Telemetry

The National Advanced Spectrum Communications Test Network conducted a test campaign to evaluate impacts of advanced wireless services - 3 long-term evolution uplink (1755 MHz - 1780 MHz) signals on adjacent Lband (1780 MHz – 1850 MHz) aeronautical mobile telemetry air to ground links. The test campaign applied a host of field and laboratory-collected long-term evolution uplink waveforms to an aeronautical mobile telemetry system in a highly automated, cabled testbed. We showcase the test methodology and lessons learned of a susceptibility study in the adjacent band as applied to a telemetry receiver under test.
