A drive test measurement approach to characterize on-vehicle 2×2 LTE-MIMO antennas

Abstract

This paper presents the use of a commercially available radio scanner for characterizing on-vehicle 2×2 Long-Term Evolution (LTE) radio Multiple-Input Multiple-Output (MIMO) antennas. The scanner measures the LTE eNodeB, i.e. the cell base station, reference signals and each channel and determines the MIMO channel matrices from which the downlink throughput can be determined. For a given LTE radio, this measurement approach can be very useful for efficient comparison between MIMO antennas or among different antenna locations on the vehicle.
