| Our long experience
in connection gave us a very high level of technical competence
that we share with our clients through several services listed below: |
|
|
|
|
Radio
transmission measures
|
|
This service is realised before the functioning of an installation. It consists in validating the radio performance in comparison with the schedule of conditions of the operator.
Our technicians measure, verify the length, attenuation and V.S.W.R of the feeders, active or passive duplexers gain and insertion loss, amplifications gain, decoupling measures and cross-polar antennas insulation measures.
They realise a visual control of the general installation, the connecting assembly quality, the marking of weatherproof cables and the grounding elements.

Aerial verifications
|
|
This service consists of the verification of the antennas' azimuth and tilt. Our technicians verify the presence of other antennas and the presence of possible obstacle that could interfere the wave emission. They determinate their angular position in comparison with the antennas' azimuth.
|
| |
|
Functioning installation audit
|
|
This service consists of a global verification of the installation. A visual verification of the whole support, the corrosion on the elements, the conditions of the antennas, the weatherproof of the connectors, the jumpers, the grounding elements and the presence of security elements on the pylon.

|
Preventive maintenance control
|
|
This service consist of the verification of antennas tilts and azimuths plus the global R.O.S measure for all cables. In case any problem is noted, we analyse and localise the found defect.
|
| |
| Site research |
|
For this step, we have a computerised tool which enables to determine the best site to be chosen, the most appropriate system of antennas and also to optimise the covered area. The proposed service includes a computerised map-making allowing to determine the best point of emission for a cellular network and also provides a diagram corresponding to the radiating zone of each type of antenna, and also on demand, all the possibilities for the antenna's coupling.
|
|
The above studies enables to define, for a given site, the most appropriate type of antenna according to the relief or the area and then to simulate in real time the antenna's coupling configuration for one or several azimuths. This makes easier the choice of the antenna to be mounted or coupled in a record time. Thanks to this, the best configuration is found.
