This post is about the GSM-R coverage planning. Please read further down to find more guidance.

GSM-R Network Structure - Common Single Network



1. Low costs;

2. Easy radio parameter setting;

3. Efficient use of frequencies;

4. Minimum sites.


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

2. Lowest security level

GSM-R Network Structure - Overlapped Redundancy Coverage



1. BTS redundancy design;

2. Medium costs;

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


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



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.


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