To avoid human disasters

Large buildings must be secured to protect thousands of people pass through every day and essential infrastructures. In case of incident and terrorist attacks, the probability of human and economical disaster is extremely high.

Reliable critical communications

Fire Brigades, Ambulances, Police, Customs, and Army, need a robust and reliable radio coverage system to communicate inside any location of the buildings with the same efficiency as outside.

Reliable operating communications

During maintenance and services operations, buildings operators need an efficient private communication network to work quickly and safely to reach the best cost-efficiency.

Mobile phone communications

Workers, customers, travellers claim to be always connected to their mobile applications everywhere. Despite the wave resistance of modern buildings, in-building services (IBS) must include a high speed multi-operator radio network.

Solutions for smart buildings

As new technologies are implemented in buildings to make them smarter, sensors and probes retrieve parameters such as air quality, flood, temperature, pressure, human presence, etc… These wireless devices can communicate on Internet of Things (IoT) networks.

Solutions for Industry 4.0

Automated factories need dramatically radio solutions at each stage of production process to control the machines or to track the goods.

Fully integrated solution

For each building, SEE TELECOM proposes customized engineering to retransmit all the requested radio networks. RF signals are picked up, multiplexed, and converted into optical signals in the master station. The signals are then distributed by optical fibre down to the slave stations, which they are converted back into RF, amplified and multiplexed. The slave stations are connected to the radiating part, composed of a single leaky feeder that covers the complete length of the corridors or the underground parking, and some antennas in offices and technical rooms. For small buildings, single off-air repeaters, feeders and antennas will be deployed.

Optimized radio coverage

SEE TELECOM’s Architecture Team designs radio coverage system with its large knowledge and experience, combined with the latest modern technology as iBwave® software to optimize engineering and cost-efficiency.

Services without limits

Thanks to our digital broadband technology, all 1- and 2-way radio networks can be rebroadcasted:

  • AM, FM, DAB
  • VHF simplex, duplex
  • DMR, DMR Tier 3, eDMR, MPT1327
  • UHF simplex, EDACS
  • TETRA, TETRAPOL, TEDS
  • P25, LTE
  • Internet of Things (IoT), WIFI
  • Etc…

User-friendly monitoring software

SEE TELECOM has developed useful monitoring tools to be placed in the control room of the tunnel :

All connections are full IP with a 1 Gbit Ethernet network on the optical fibre between master, slaves and probes. The monitoring can know in real time the status of each part and leaky feeder.
