Mikrovågsnät

Mikrovågsnät, or microwave networks, are communication systems that use radio waves in the microwave frequency range to transmit data. These networks can operate over long distances, making them suitable for various applications. They are often employed for point-to-point communication, connecting two fixed locations, such as between cellular towers, for backbone networks, or for providing internet access in areas where traditional wired infrastructure is impractical.

The technology relies on directional antennas that focus microwave beams towards a receiver. This directional nature helps to minimize interference and maximize signal strength over the intended path. Microwave links can consist of a single hop or be part of a chain of multiple hops to extend the communication range. The capacity of a microwave network is determined by factors such as bandwidth, modulation schemes, and the specific frequencies used.

Advantages of mikrovågsnät include rapid deployment compared to laying fiber optic cables, flexibility in routing, and the ability to overcome geographical obstacles. However, they can be affected by atmospheric conditions like heavy rain or fog, which can attenuate the signal. Regulatory bodies often assign specific microwave frequency bands to different services to prevent interference. Mikrovågsnät play a crucial role in modern telecommunications infrastructure, complementing other technologies to ensure robust and widespread connectivity.
