Microwave signals are electromagnetic waves with frequencies typically ranging from 300 MHz to 300 GHz. They are a part of the radio spectrum, used for transmitting both information and energy.
They are widely used in wireless communication (e.g., Wi-Fi, cell phones, satellite TV), radar systems (weather, air traffic control), industrial heating, and domestic microwave ovens for cooking.
Key advantages include their ability to carry large amounts of data (high bandwidth), enable long-distance communication, and provide precise detection and imaging in radar systems due to their shorter wavelengths.
Low-power microwave signals from everyday devices like cell phones and Wi-Fi are generally considered safe within established guidelines. High-power exposure, as in an active microwave oven, can cause heating effects but is typically contained.
