Description
The main scenario for communication with railway train is within the railway transport system is the following (see Figure 1):
- BS sectors are installed along the railway lines.
- CPEs are installed in the head and last railcars. By default, CPEs with omni omnidirectional antennas are used, however, a scheme with directional antennas is also possible. The use of directional antennas will increase the processing time during the calculation time at the planning stage, but will reduce the total number of used BS sectors.
- One of the BS is used as an aggregation node, but it is possible to have a separated separate aggregation node. An InfiMUX switch is installed at the aggregation node and the backbone links - main and backup, connect it with the control center.

The features specific feature of such scenarios is the high train maximum speed of the train, which will require careful BS location planning and careful wireless devices' configuration.
Configuration
For railway transport the following settings are recommended:
- joining all of all BS sectors into a single MINT area using the InfiMUX installed on the aggregation node;
- mobile mode;
- MultiBS function enabled;
- Global function enabled.
...
The following projects were implemented by InfiNet Infinet in accordance with the above scenario above:
