Performance analysis and modeling based on LTE-A field measurements: a city center example

This study analyzes the LTE-A network based on actual field measurements. Measurements were conducted at 80 locations in the Samsun, Turkey, city center, using TEMS Investigation software. RSRP, RSRQ, SINR, CQI, and throughput values were recorded in a stationary position for each measurement while downloading 500 MB of data. The averages of these recorded data were calculated, and detailed analyses were performed. The effects of RSRP, RSRQ, SINR, and CQI on the throughput value in the LTE-A network were examined, and a novel mathematical model was proposed that gives the relationship between them with 88.85% accuracy. It was also observed that the accuracy of the proposed model could be increased by 4% with GRNN.
