Technology Status And Development TrendTechnology 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.

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 TechnologyThe 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 FlexibilitySupports 1.4/3/5/10/15/20MHz network according to the requirements

Limited to 20MHzBandwidth of 2.4G

Costs OfConstruction 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
