Working Group 5 Draft Report On Sub Working

Working Group 5 Draft Report On Sub Working Group Conclusions 1

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 2

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 WG 5 agreed assumptions may change the range of required protection distances and in turn may render different conclusions • Identified Possible Future Analysis 3

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 4

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 5

Sub Working Group Precision Guided Munitions/Other Airborne Systems Conclusions: • 8 Systems Identified • PGM, Tacti. Link, 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 6

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 7
