The Singapore MRT u The current MRT Network is operated by Singapore Mass Rapid Transit Ltd (SMRT) and Singapore Bus Service Transit Ltd (SBST). Land Transport Authority

The Modern MRT Highly Automated. u Increasingly Reliant on Fail-Safe Computer Based Systems. u Decreased Staffing Levels demands more effective means of communication. u Highly Reliable and Flexible Radio Communication is required for effective command control purposes. u Land Transport Authority

Fully Automated MRT Fully automatic operation requires that all functions of the driver be automated. u Operation Control Centre must become the driver’s eye. u Efficient data transmission plays a key role in rapid indication and diagnosis of train-borne system faults. u Consistently clear communication with passengers is essential at all times. u Land Transport Authority

Radio Requirements Digital Technology u. Benefits from Digital Signal Processing. u. Robust and Reliable Communication Link. u Combined Voice and Data Services u. Simultaneous Voice and Data Transmission. u Land Transport Authority

Radio Requirements u Automated Resource Management u. Bandwidth Occupancy only when Needed. u. Increased Capacity through Shared Resources and Trunking Schemes. Land Transport Authority

Radio Requirements u Ease of Expansion Modular System. u Support Future Network and Channel Growth. u u Advanced Networking Capabilities u Inter-working with Other Networks. Land Transport Authority

Radio Technology Why TETRA ? Land Transport Authority

Why TETRA ? u Frequency Economy u u Security for Critical Data u u Interleaving 4 Channels in a single 25 k. Hz Carrier via TDMA scheme. Data Integrity through Forward Error Correction. Consistent Voice Quality No Analogue Circuit Degradation Caused by Noise and Distortion. u Less User Frustration and Stress. u Land Transport Authority

Why TETRA ? u Flexible Communications Supports both Voice and Data applications. u Efficient Command Control (fast call set-up, subscriber identification, priority management, individual, group and broadcast calls). u Land Transport Authority

Why TETRA ? u Automated Voice/Data Traffic Routing and Network Flexibility Software Based Configurable Architecture. u Trunked System Controller. u Roaming between Systems. u Land Transport Authority
