SAIT France has a long experience in radio re-transmission in confined environments.
This particular expertise was confirmed by the achievements made in various tunnels of undergrounds in France and in several cities around the world.
All the techniques applied in this particular application are familiar to SAIT France : leaky cables, fiber optics, antennas, repeaters, break-ins, …

SAIT France can assume these projects from the feasibility study up to the implementation of the global system.
