Which frequency range is utilized by microwave links?

The frequency range utilized by microwave links is indeed accurate when identifying the bandwidth from 300 MHz to 300 GHz. Microwaves are electromagnetic waves with frequencies generally in this range and are widely used in various communication technologies.

Microwave links typically operate in specific bands, allowing for effective data transmission over distances via line-of-sight methods. The coverage of 300 MHz to 300 GHz includes sub-ranges used for different types of communication, such as cellular, satellite, and point-to-point microwave systems.

The other options reflect narrower ranges that do not encompass the full spectrum of microwave frequencies. Although some microwave applications may specifically use segments like 3 GHz to 10 GHz or higher frequencies like 30 GHz to 40 GHz, the broad definition takes into account all frequencies classified as microwaves, making the range of 300 MHz to 300 GHz the most comprehensive and correct choice. This breadth allows various systems to leverage the advantages of microwave transmission, such as reduced interference and increased bandwidth.
