Wireless Network Measurements

Radio interface measurements are essential in the deployment and operational phases of cellular networks. The physical radio interface can be investigated by monitoring and storing numerical values about the received power level over the functional bandwidth. The global system for mobile communications (GSM)/general packet radio service (GPRS) equipment can typically be used to record and monitor radio network occurrences and parameter values. Long term evolution (LTE) radio interface is based on Orthogonal Frequency Division Multiplexing (OFDM) in downlink, and on the Single-Carrier, Frequency Division Multiple Access (SC-FDMA) in uplink. The LTE field measurements indicate a feasible performance of the system in typical radio conditions. In the trial and commercial LTE network deployment, the maximum data speed is much higher in the radio interface compared to any other previous mobile communication network.
