Legislation¶

Radioelectric frequencies belong to the State public field. There are international and national regulation agencies that allocate part of the frequency bands of the spectrum to users, with a limited bandwidth and a maximum emission power authorized for the equipment.

In France, the ANFR (Agence Nationale des Fréquences) is the agency in charge of the frequency allocation and regulation of frequency bands, and license delivery. The TNRBF (Tableau National de Répartition des Bandes de Fréquences) is the reference document which precises to what radiocommunication service and which user (Defence, ARCEP, MeteoFrance...) each frequency band is allocated in France.

Only the ANFR can provide the input we need for our system design, which are:

• the frequency band
• the available bandwidth
• the emission power (EIRP) authorized for our link

Any radiocommunication system must absolutely respect the legislation and carefully study the regulatory aspects of his application. However, in case of low power/short range application, the ANFR offers some "free bands", as we will see in the following.
