Working Group 5 Draft Report On Sub Working Group Conclusions
WG 5 Approach • Performed interference analysis in both direction • Government systems to LTE • LTE to Government Systems • Determined separation distance for federal operations and LTE systems
Sub Working Group Aeronautical Mobile Telemetry (AMT) Conclusions: • Sharing is not feasible between AMT and LTE • Range of separation distance requirements would severely limit LTE deployment in top 100 commercial markets • Changes to WG5 agreed assumptions may change the range of required protection distances and in turn may render different conclusions • Identified Possible Future Analysis
Sub Working Group Small Unmanned Aerial Systems Conclusions: • Sharing does not appear feasible, based on the analysis result identifying large separation distance requirements • Industry view at this time is conclusion cannot be assessed due to insufficient Publicly Releasable Data • Analysis Focused on Protection Distances • UE to SUAS: beyond 300 KMs • SUAS to Base Stations: at least 285 KMs • Identified Possible Future Analysis
Sub Working Group Air Combat Training Systems Conclusions: • Sharing would likely impose unacceptable operational or economic constraints on ACTS operators or wireless operators. • UE to ACTS: 325-375 KM distances • ACTS to Base Stations: 285-415 KM distances • Identified Possible Future Analysis, including some sharing techniques
Sub Working Group Precision Guided Munitions/Other Airborne Systems Conclusions: • 8 Systems Identified • PGM, TactiLink, VORTEX, ROVER, DRAGOON, LITENING/Sniper: • Relocation to comparable spectrum • JTRS AMF: • Protection Zones at selected priority areas for entire band/elsewhere 1780-1850 MHz • TTNT (exc Navy): • Protect DOD priority sites for entire band 1755-1850 MHz
Future Analysis Options Identified • Time-based & Geographic-based Sharing • Off-tuning of LTE Base Stations • Notching specific LTE channels at selected locations • Alternate interference threshold based on desired signal level desired • Possible effects of clutter/terrain • UE Antenna Height
