Chapter 1: Site Installation
1.1 Scope of This Chapter
This chapter describes how to physically install the equipment for the Transportation
FiberinMotion solution.
FiberinMotion solution.
1.2 Track Side
1.2.1 Overview
The Fiber in Motion solution uses vertical antennas, and relies on antenna spacing to
differentiate the radio streams enough so as to enable MIMO.
differentiate the radio streams enough so as to enable MIMO.
General Guidelines
• 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.
• The lowest antenna must be higher than the highest rail car on the line.
Power
• Use the PoE to supply power to the TBS (either an outdoor or indoor PoE).
• Use the PoE or the SFP fiber connection to provide a service connection to the
TBS.
• Install two Lightning Protection Units (LPU): One close to the TBS, and the other
close to the PoE.
Minimum Recommended Distances
There are three antennas for each stream: A is for approaching trains, and B is for
receding trains (see
receding trains (see
). Separate the antennas as much as possible, and
maintain the following minimal distances:
• Minimum vertical distance between each antenna is 1.0m.
• Minimum horizontal distance between Antenna 1 and Antenna 2 is 1.6m.
• Minimum horizontal distance between Antenna 1 and Antenna 2 is 1.6m.
