Fresnel Zone

by Ulf SeijmerBlog posts 23 April, 2023Comments are Disabled

One of the essential concepts in wireless communication is the Fresnel zone. An elliptical region surrounds a straight line-of-sight communication path between two points. The Fresnel zone plays a crucial role in wireless communication. It determines the clearance required between transmitting and receiving antennas to ensure that the transmitted signal is received with minimal interference. …

Link budget calculation and examples

by Ulf SeijmerBlog posts 16 April, 202314 April, 2023Comments are Disabled

A link budget shows how a communication signal is amplified and weakened in a link, a connection in a communication system. Although link budgets can cover everything from coaxial cable networks to fibre or radio links, we will focus on radio links in this post. Radio links like mobile or private radio networks behave similarly …
