Microwave link

Microwave link

A microwave link is a communications system that uses a beam of radio waves in the microwave frequency range to transmit video, audio, or data between two locations, which can be from just a few feet to several miles apart. Microwave links are commonly used by television broadcasters to transmit programmes across the country, for instance, from an outside broadcast back to a studio.

Mobile units can be camera mounted, allowing cameras the freedom to move around without trailing cables. These are often seen on the touchlines of sports fields on Steadicam systems.

Properties of microwave links

* Involve line of sight (LOS) communication technology
* Affected greatly by environmental constraints
* Have limited penetration capabilities

Uses of microwave links

* In communications between satellites and base stations
* As backbone carriers for cellular systems
* In short range indoor communications

ee also

* Microwave Transmission
* Microwave power transmission
* Microwave radio relay
* Fresnel zone
* Path loss
