Advantages:


1. Low costs;


2. Easy radio parameter setting;


3. Efficient use of frequencies;


4. Minimum sites.


Disadvantages:


1. No service is available when a BTS is faulty;


2. Lowest security level


GSM-R Network Structure - Overlapped Redundancy Coverage

Advantages:


1. BTS redundancy design;


2. Medium costs;


3. When BTS C is faulty, BTS A and BTS B can provide continuous coverage.


Disadvantages:


1. Frequent handovers deteriorate service quality;


2. Complicated frequency planning, especially for highly overlapped areas;


3. More sites and large costs in mapping devices.



GSM-R Network Structure---Co-Site Dual-Coverage

Advantages:


1. System-level redundancy design,high security


2. Less requirements on sites (equipment room and tower shared)


3. BTS B takes over services of BTS A immediately after BTS A is faulty.


4. This avoids service interruption due to device faults.



Disadvantages:


1. When frequency sharing is enabled, services will be interrupted for a short time during the device switchover.
