碩士 === 亞東技術學院 === 資訊與通訊工程碩士班 === 106 === Long Term Evolution (LTE) is the fourth generation (4G) mobile communication system with a significant improvement in its cell coverage and cell capacity compared with the third generation Universal Mobile Telecommunication Systems (UMTS); however, verification through field measurement is required. The measurement in this study was conducted using a TEMS Pocket engineering model test phone, through which the cell coverage and cell capacity of LTE were analyzed using the KPI parameters of packet switch (PS) between the 4G EnodeB base stations (BSs) and user equipment (UE). The measurement location was Banqiao District, New Taipei City, in Northern Taiwan; the measurement range focused on densely populated areas in Banqiao District with a north–south distance of approximately 5 km. Of the 80 EnodeB BSs that were measured, 700 MHz, 1800 MHz, 2600 MHz is operator A supported, 900 MHz is operator B supported and 46 supported the 700 MHz band, 35 supported the 1800 MHz band, and 6 supported the 2600 MHz band. The UE measurement was performed during May 2016.Record files obtained from measurements were used for parameter sampling and signal quality analysis using the analysis software Actix. Analysis content was as follows: MCS, RSRP, SINR, Tx/Rx bandwidth, and throughput. A complete comparison of the antenna pattern compensation theoretical and actual values of correlation analysis and signal coverage is thus presented.This paper using longitude and latitude coordinates to deduce the linear distance between base stations and signal points. Continuation of the existing all-MCS weighted cell range calculation method. To calculate the Multi-EnodeB, Single EnodeB and Single EnodeB with Different modulation technology All-MCS weighted cell range and coverage probabilities.The results of data analysis determined that, when Multi-EnodeB、Single EnodeB and Theoretical Area Coverage Probability receiver sensitivity was −105 dBm, the area coverage probability was 59.07%、55.96%、99.73% at 700 MHz; the area coverage probability was 88.32%、88.22%、99.48% at 900 MHz; the area coverage probability was 48.79%、45.77%、99.19% at 1800 MHz; the area coverage probability was 41.63%、39.33%、97.2% at 2600 MHz. Overall, the area coverage probability of the Theoretical Area Coverage Probability average exceeded that of the Multi-EnodeB & single serving eNodeB.
