LTE UE receiver performance measurements

LTE user equipment (UE) receiver performance has significant impact to cellular radio network coverage and capacity. It determines the maximum data throughput across the air interface between the LTE base station (eNB, evolved node B) and the mobile network subscriber UE, thus it determines the total capacity across the air interface. Therefore, it is one… Read more »
