碩士 === 國立成功大學 === 電信管理研究所 === 100 === There are three types of monitoring stations in radio monitoring systems; each type of stations has to execute different monitoring tasks. Each signal type has its own characteristic and the data needed to be sent. Thus, the required bandwidths of different monitoring tasks are different. This research uses the amount of data which occur in executing monitoring task to calculate the bandwidth requirement between remote monitoring stations and regional centers. According to the results of this research, the raw data for signal analysis and identification task is too large. It is recommended that the remote monitoring station can be equipped with receivers which have digital demodulation functions to reduce the transmission load. Except the signal analysis and identification task, the maximal bandwidth requirement of fixed monitoring stations is 1.25Mbps which occur in data transmission task for the night. Therefore, fixed monitoring stations should select transmission rate of 2Mbps of FTTB or ADSL. The biggest bandwidth requirement of mobile monitoring stations is 0.31Mbps which produced by transmitter coverage measurement. Thus, mobile monitoring stations should use the transmission rate up to 0.384Mbps UMTS wireless network. The highest bandwidth requirement of transportable monitoring stations is 0.425Mbps which occur in signal measurement. Therefore, transportable monitoring stations should select theoretical transmission rate of 5.76Mbps HSUPA wireless network. Besides, transmission rate of 1Gbps of FTTB can satisfy the bandwidth requirement between the regional center and control center.
