2.1 Scope of This Chapter
This chapter describes how to install the equipment for the Transportation FiberinMotion
solution.
solution.
2.2 Wayside
The Fiber in Motion solution uses multiple antennas to enable MIMO and Diversity modes.
The solution relies on antenna spacing, as well as dual polarization / dual slanted antennas to
differentiate the radio streams.

2.2.1 Overview
General Mounting Arrangement
The TBS can be mounted on a pole or a wall, together with its antennas, LPUs and PoE device.
To enable better MIMO conditions, the antennas should be divided between vertical and
horizontal polarizations.

shows a schematic view with these polarizations.
• Place the tower/TBS at the location determined by the site survey.
• Make sure there is sufficient line‐of‐sight towards the track segment the antennas
will cover
• Make sure that there are no obstacles directly in front of the antennas
• The lowest antenna must be higher than the highest rail car on the line
