Using technology SHBD (topology MESH), it becomes possible to merge into a single information network of railway infrastructure: transport, crossings, bridges, stations and mobile composition. With the help set up an information network, many applications will be addressed challenges facing the operation of the railway service.
The problem:
Ensuring high-speed wireless connectivity:
- Sistem monitoring of important sites, stations, transport, travel. - Moving objects - trains, trains, maintenance crews ways. - Statsionarnyh Objects posts located at a distance from each other.
transfer of large amounts of data among all groups of objects listed in random order.
Establishment of a system of operational monitoring long objects (rail tracks).
Transfer video, data telemetry, bilateral high-quality voice traffic.
Creating video surveillance systems, remote sites - stations, crossings.
Existing reservation systems.
Advantages networks Vita-railways over existing wireless networks:
The simplicity of installation along the longest network facilities (rail tracks)
Besshovny hendover. The opportunity to reception transmission devices on the rolling stock.
Use of rolling stock as part of the network, with the possibility of transmission of streaming video from / to the convoys.
Low cost nodes.
Ability to rapidly expand the network.
Network nodes can be installed on existing infrastructure elements: lighting poles, power lines, buildings, stations, rolling stock.
Ability to connect to the main wired network to connect to the Internet.
