Initial analysis and lab experiments have provided positive confirmation of the viability of 4G LTE Cellular Technology for Aeronautical mobile telemetry. COTS LTE equipment is deployed for the test range frequency bands. The high speeds of test articles TAs can be addressed with a UE add-on applique customized to compensate for the Doppler shifts. The applique has worked effectively with the LTE physical layer. To achieve spectrum efficiency, a multi-cell network is planned. Mobility is managed with native LTE handovers. To address extreme Doppler cases, additional support is provided to mobility management via a central entity that estimates the TAs trajectory and issues handover commands. Within this framework we present aspects of an RF planning study covering the air space around the Edwards Air Force base. The analysis is conducted with a custom RF planning tool to assess signal strength, interference and achievable rates from a placement of cells at various locations in the test range, with antenna pointing that is relatively restricted. Results cover eNB density, antenna pointing strategies, backhaul needs, achievable rates, and multi-user aspects.
