Cours Transmission Par Faisceaux Hertziens Pdf __top__ Download

Courses on Transmission par Faisceaux Hertziens (Microwave Radio Links) are essential for telecommunications students and engineers. They cover the design and maintenance of point-to-point wireless links that operate typically between 1 GHz and 40 GHz. These systems are crucial for interconnecting distant sites for telephony, television, and mobile data (GSM). Core Course Topics

5. Impairments and Fading

• Multipath Fading: Caused by reflections from water or flat terrain.
• Rain Attenuation: Critical for frequencies above 10 GHz.
• Atmospheric Ducting: When humidity gradients trap beams.
