Rail Transit Development Programme
Rail Transit SystemBy Y2015
The current MRT Network is operated by Singapore Mass Rapid Transit Ltd (SMRT) and Singapore Bus Service Transit Ltd (SBST).
Increasingly Reliant on Fail-Safe Computer Based Systems.
Decreased Staffing Levels demands more effective means of communication.
Highly Reliable and Flexible Radio Communication is required for effective command and control purposes.
Fully automatic operation requires that all functions of the driver be automated.
Operation Control Centre must become the driver’s eye.
Efficient data transmission plays a key role in rapid indication and diagnosis of train-borne system faults.
Consistently clear communication with passengers is essential at all times.
Benefits from Digital Signal Processing.
Robust and Reliable Communication Link.
Combined Voice and Data Services
Simultaneous Voice and Data Transmission.
Automated Resource Management
Bandwidth Occupancy only when Needed.
Increased Capacity through Shared Resources and Trunking Schemes.
Ease of Expansion
Support Future Network and Channel Growth.
Advanced Networking Capabilities
Inter-working with Other Networks.
Why TETRA ?
Interleaving 4 Channels in a single 25kHz Carrier via TDMA scheme.
Security for Critical Data
Data Integrity through Forward Error Correction.
Consistent Voice Quality
No Analogue Circuit Degradation Caused by Noise and Distortion.
Less User Frustration and Stress.
Supports both Voice and Data applications.
Efficient Command and Control (fast call set-up, subscriber identification, priority management, individual, group and broadcast calls).
Automated Voice/Data Traffic Routing and Network Flexibility
Software Based Configurable Architecture.
Trunked System Controller.
Roaming between Systems.

Depot Control Centre
Open Standard Interfaces
Voice Communication across Multiple Virtual Private Networks.
Interconnections with other TETRA compliant Networks.
Software Control of All Aspects.
Easily Upgradable, Scaleable, Expandable
Programmable Options provide Flexibility.
Fully Synthesised, not Hard-wired.
Modular Hardware Design.
Ease in Migration of System Control
Control Functions can be allocated at any Dispatcher Location through Soft Configuration.
LTA has chosen TETRA for the following main reasons:
Feature Rich Radio System.
Provides Secure and Highly Reliable Concurrent Voice and Data Communications.
Highly Flexible and Expandable Catering for Future Needs and Network Expansions.
Modular and Upgradable Software based System Protects the Investment.
It is for these reasons that Singapore has chosen TETRA as the preferred technology to support the operation of the Singapore MRT operations.
TETRA is likely to be the choice for future MRT lines as the transit infrastructure in Singapore continues to grow rapidly.
