Railway Communications Go Wireless

The railway market now demands networks of greater reliability and availability in order to deliver improved traffic safety, more satisfying passenger services, and higher operational efficiency. Proven wireless LAN technologies can greatly upgrade the operation and maintenance of trains and rail infrastructure. To fulfill this potential, next generation wireless railway communications systems must meet the following key requirements:

Reliability

Continued wireless communications must be secured despite potential interruptions or failures on the communication path.

Coverage

Rail wireless solutions must provide ubiquitous coverage of all areas where trains are likely to operate. Advanced wireless AP architectures and roaming technologies may be needed to achieve this goal.

Safety

Wireless APs, Ethernet switches, and endpoints must meet certification criteria for safe railway operations, such as vibration, shock, extended temperature range, humidity, EMC, etc.

The Next Generation of Wireless Railway Communications

Non-interference

The railway network must be resistant to noise and multi-path interferences

Manageability

The security, reliability and performance of the solution must be easy to administer and maintain.

Future-proof

An open standards-based network with large bandwidths is required for applications today, tomorrow, and beyond.
