In-Building Radio Coverage GSM UMTS LTE 2G 3G 4G TETRA TETRAPOL
Weary look for level bars on your mobile? Exasperated not be able to call from your business premises? Your customers or users complain of not being able to use their mobile phone?
Indeed, the high-rise buildings and large infrastructures are composed of materials that prevent good penetration of the signal from the antennas inside the building: windows treated, reinforced concrete, etc ...

SELECOM offers solutions to bring the GSM / UMTS / LTE signal inside buildings.

Coverage Solution of small surfaces

To cover a small area of ​​such building, underground parking, large houses, the typical solution is: 
  • A roof antenna picks up the signal from the surrounding BTS
  • An off-air repeater RF / RF filters and amplifies the signal 
A distribution system of antennas (coaxial cables, antennas ceiling, wall antennas) is installed in the building to provide radio coverage 
This solution is offered with several options: 
  • Single-operator or multi-operator
  • Single or Multi-standard standard (2G, 3G, 4G)
  Parking Radio Coverage GSM UMTS LTE 2G 3G 4G TETRA TETRAPOL

Commercial Centers, Stadiums, Airports Radio Coverage GSM UMTS LTE 2G 3G 4G TETRA TETRAPOL  

Coverage Solution of big surfaces

To cover large infrastructure such as: 
  • Office buildings 
  • malls 
  • airports 
  • stadiums 
  • Etc ... 
The solution consists of a DAS (Distribution System Antenna): 
  • BTS operators and base stations PMR / DMR / TETRA are installed in a dedicated local 
  • A nodal RF / optical mixed signals 
  • An array of optical fibers running through the infrastructure to remote repeaters, themselves connected to antennas (coaxial cables, antennas ceiling, wall antennas) 
This solution is offered with several options: 
  • Single-operator or multi-operator 
  • Single or Multi-standard standard (2G, 3G, 4G, TETRA, TETRAPOL

Couverture Solutions of industrial complexes

Industrial buildings often have a fatal flaw: composed of metal walls, pipes, etc ... the waves propagate poorly in these complex and communications are sometimes very difficult. In addition, the sometimes complex environments require drastic precautions, such as products with ATEX standards for petrochemical complexes. 

SELECOM offers a complete range of solutions for relaying radio industries, whether for mobile networks 2G, 3G, 4G and for réseauw PMR, DMR UHF, TETRA, TETRAPOL.
