| Popis: | 97 Currently, the Wideband Code Division Multiple Access (WCDMA) technology has already been generally applied to the cellular communication system of various countries. Though most 3rd generation systems have already erected the platform of many bases, transceiver station is Node B in universal mobile telecommunications systems. Some areas, such as high buildings and underground tunnels, must install a simple and stable system to improve the intensity of the signal, which can improve the quality of the communication network. This thesis investigates the fiber repeater (FR) systems which applied for radio over fiber (RoF) technology in mobile phone coverage working with Metro High-Speed Railway and Subway such as analysis for public coverage of an indoor transition system. This thesis is based on the theory and practical engineering principle which provide guidelines and formulas for a link budget design to help network planning companies and Telecom operator designers fully control and analyze the single output power of uplink and downlink between fiber repeaters and mobile phones as well as base stations. Finally, the results of this leakage cable (LC) system are practically applied to an indoor coverage design for Taiwan Railway Administration System. |
