3. International Telecommunication Union Committed to connecting the world Technology Status And Development Trend The requirement of Rail Transit Informatization are rising Control Center use the real-time monitoring to control the running train, and provide a wealth of real-time information service for passengers. It will improve the operational management, efficiency and quality of service. Now the Digital Broadcast Television and WLAN technology can not meet the requirements of High- Bandwidth services during the High-Speed movement Restricting The development of Rail Transit Informatization TD-LTE technology with High-Bandwidth, High Mobility, Seamless Handover performance. It is one of the most mature and advanced communication technology, which will meet the wireless communication requirements of the Rail Transit.

4. International Telecommunication Union Committed to connecting the world The advantages of TD-LTE Technology TD-LTEWLAN Anti-Interference Capability Private Band, Low Interference ; Use ICIC ， IRC Anti-Interference Tech ， Solve the in-system interference problem Public Band, Inevitable External Interference ； Lack of Anti-Interference Tech within the system ； Throughput Rate At 10MHz bandwidth. Uplink and downlink resources 1: 1, the downlink peak is 20Mpbs and the uplink peak reach to 8Mbps. Also the uplink and downlink rate are adjustable. In the actual project, using 20MHz bandwidth, downlink peak is 15Mbps and uplink peak is 2Mbps. Mobility With Anti-Frequency Shift algorithm, supports over 300Km/H movement, fully meet the speed requirements of Urban Rail Transit. WLAN as a fixed wireless access technology, mainly used in slow movements. No Anti-Frequency Shift algorithm. Band Flexibility Supports 1.4/3/5/10/15/20MHz network according to the requirements Limited to 20MHz Bandwidth of 2.4G Costs Of Construction And Maintenance Can use the Leaky Coaxial Cable The output power of AP is so low that we need to place an AP each 200 meters, so it is not suitable for Leaky Coaxial Cable, also the construction is difficult and maintenance costs will be high. Coverage Distance Single RRU can cover 1.2Km in tunnels Single AP 200m
