Research of a frequency band¶

When designing an RF link, one of the first parameter required to study the system performance is the frequency band available and its assoiated bandwidth. In fact, the frequency spectrum is shared among users in order to regulate RF emissions, and avoid interferences among various equipments.

There are two approaches when researching a suitable frequency band for an application:

• Approach n°1 is the fastest, and consists in searching among “free bands” one that could fit our application, in term of bandwidth and emission power available.
• Approach n°2 requires more time, and consists in searching in the TNRBF an available bandwidth and sending a “request for allocation” to the ANFR.
