The signal strength decreases by 20 dB over a distance of 10 km, so the distance between the transmitter and receiver is:

The principle of Faisceaux Hertziens is based on the concept of electromagnetic waves, which were first described by James Clerk Maxwell in the 19th century. These waves have both electric and magnetic field components, which oscillate at right angles to each other and to the direction of propagation.

f = 10 GHz = 10 × 1 0 9 Hz

d = D × 1 0 20 L ​

However, this is not the correct answer. Using the correct formula for signal attenuation:

In conclusion, Faisceaux Hertziens are an essential concept in telecommunications and electromagnetic theory. The exercice corrigé Faisceaux Hertziens PDF provided in this article demonstrates the principles and characteristics of Faisceaux Hertziens, including frequency, wavelength, polarization, and directionality.

Faisceaux Hertziens are directional beams of electromagnetic radiation, typically in the radio frequency range, that are used for wireless communication. They are designed to propagate through free space, such as air or vacuum, and are used to transmit information over long distances.
