Turn-key solutions for wireless radio communications systems in areas with difficult radio communications.

Ensuring radio coverage in areas which do not generally have satisfactory radio coverage from exterior transmitters, like tunnels, underground constructions, buildings and large covered or underground parking areas is a SAIT specialty. SAIT offers professional solutions that ensure a reliable communication in these Confined Areas. Whatever the radio signal is, we provide network coverage!

Tunnel coverage solutions

Tunnels are typical examples of Confined Areas, areas where there is limited or even no radio network coverage available. Due to the structure and construction of a tunnel (cement, concrete, stone, etc.) radio signals, like TETRA, GSM, FM and DAB can’t get through which results in no network coverage and thus no ability to communicate in these locations.

For several organizations, like police and fire man, security organizations, as well as mobile telecom operators network coverage in these environments is desirable and for the former even required to ensure safety.

SAIT offers solutions that make communication in tunnels possible. The total solution of SAIT undertakes the design, installation and commission of the passive components (cables, antennas) as well as the active components (repeaters) of a Confined Area solution. Easily said, the implemented solution captures the outdoor radio signal – TETRA, analogue signal, GSM, work channels, FM, etc. – and inject these signals into radiating cables or antennas which retransmission the radio signal in the tunnel. Through some carefully placed auxiliary equipment on the installation, the signals are reconditioned in order that the service delivered meets the recommendations of the tunnel operator and the communication quality satisfactory to the users.

Indoor coverage solutions

Many indoor locations, like buildings and large covered or underground parking areas have limited or even no radio network coverage available. Due to their structures and some construction characteristics (cement, concrete, stone, metal, etc.) radio signals can’t get trough and thus communication in these locations isn’t possible, or is not reliable enough.

For several organizations, like police and fire man, security organizations, as well as mobile telecom operators network coverage in these environments is desirable and for the former even required to ensure safety.

To ensure indoor radio coverage, SAIT offers solutions that undertake the design, installation and commission of the passive components (cables, antennas) as well as the active components (repeaters) of a Confined Area solution.

Broad expertise in confined areas solutions

Throughout the years, SAIT has specialised in Confined Area solutions. Not only we can rely on an experienced Confined Areas team, but we also have a service team who is trained in after sales services to keep you solutions optimal.

Here you can find a non-exhaustive list of our expertises:

  • Emergency communication solutions: SAIT enables police, fire brigades and other public safety authorities to communicate (TETRA, PMR, Paging,…) in Confines Areas.
  • Maintenance & operations communication solutions: SAIT enables that service and maintenance teams can perform their work.
  • Mobile phone communication: SAIT enables the coverage of telecom networks and thus ensures that GSM users can use their mobile phones in Confined Areas.
  • Radio broadcasting: SAIT enables the perception of broadcasting channels and thus ensures car drivers to listen to their radio.
  • Ground-to-train communication solutions: SAIT enables the train driver to communicate with the operators in the control centre.
