CONTEXT
Created by ordinance (ord2012_293 of 21 March 2012), the
Ivorian Agency of management of radio frequencies ( AIGF
) in charge of the overall management of the radio electrical
environment in Ivory Coast,
decided to carry out a
"campaign of measurement for the validation of the
implantation of radio electrical stations in Ivory Coast
“.
It selected the company VALSCH Consulting to perform this
crucial campaign which fits into the context of global
green citizenship and sustainable management of
urban infrastructure .
This presentation provides an overview of the terms of
reference, the operating mode and the synthesis of the
results of the component Non-ionizing radiation
(NIR) of this campaign.


Terms and definition
Main Requirements :
Measures are necessary to ensure, in the general interest
: the health
and safety of persons , the electromagnetic compatibility between
equipment and facilities of telecommunications/ICT and, where
appropriate, a sound use of the radio frequency spectrum in order to
avoid harmful interference to third parties. The essential requirements
also include, in justified cases, the protection of networks and notably
associated information exchanges on control and management , the
interoperability of services and that of the terminal equipment, data
protection, the protection of the environment and the taking into
account of the constraints to urban and regional development, the
territory, the compatibility of terminal equipment and radio equipment
with devices preventing fraud, ensuring access to emergency services
and facilitating their use by disabled people.

CONCLUSION
At the end of this campaign of measures, we conclude
that in these spots, dates and hours of measures, the
levels of the fields measured comply with the limit
values for exposure to electromagnetic waves set by the
ICNIRP and that they are substantially equal to the
predicted levels.
We are provided with a venue to encourage the
regulators
of
the
telecommunications
in
the
implementation of good practices through similar
campaigns whose purposes are the application of the
precautionary principle and the contribution to the
sustainable management of infrastructure.
