Mikroradiolinkeissä

Mikroradiolinkeissä, often translated as microwave radio links, are point-to-point wireless communication systems operating in the microwave frequency spectrum. These systems are used for transmitting data, voice, and video signals over relatively short to medium distances, typically ranging from a few kilometers up to tens of kilometers. Their primary advantage lies in their ability to establish high-capacity communication paths where fiber optic cables are difficult or prohibitively expensive to install, such as crossing rivers, canyons, or urban environments with existing infrastructure.

The core components of a mikroradiolink system include transmitters, receivers, and antennas. Antennas, usually parabolic dishes, are precisely aligned to focus the radio signal towards the receiving antenna. This directional nature minimizes interference and maximizes signal strength. The microwave frequencies used, generally between 2 GHz and 80 GHz, allow for large bandwidths, enabling high data transfer rates.

Mikroradiolinkit are widely employed by telecommunication operators for backhaul connections, linking cell towers to the core network. They are also used in private networks for industrial sites, campus environments, and for emergency communication systems. The reliability of these links is crucial, and they are often deployed in redundant configurations to ensure continuous operation in case of equipment failure or signal obstruction. Factors like weather conditions, particularly heavy rain, can attenuate microwave signals, a phenomenon known as rain fade, which needs to be accounted for in system design.
