Market Size Of Urban Rail Transit Informatization
During the "Twelfth Five-Year", the
national Rail Transit will put into operation to
2500 Km. At the end of 2020, the total mileage
will reach to 7000 Km, where the informatization
is a very important part of the construction.

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.

The advantages of TD-LTE Technology
TD-LTE WLAN
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
