Estimating TIS of 4G LTE devices from OTA throughput measurements in reverberation chamber

Abstract

We show how Total Isotropic Sensitivity (TIS) of 4G Long Term Evolution (LTE) devices can be estimated from over-the-air (OTA) throughput measurements in reverberation chamber. The proposed approach is more time efficient than the standard TIS measurement method. The relative throughput itself represents Probability of Detection (PoD), and it shows clearly the quality of the Multiple-Input Multiple-Output (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM) implementation in the receiver terminal. This makes the throughput a complete metric of the receiver quality.
