Raadiosageduslikku refers to radio frequency, a portion of the electromagnetic spectrum ranging from about 3 kilohertz to 300 gigahertz. This range encompasses the frequencies used for radio broadcasting, television broadcasting, mobile phone communication, Wi-Fi, radar, and many other wireless technologies. Electromagnetic waves in this frequency range are characterized by their ability to propagate through the atmosphere and space, enabling long-distance communication.

The behavior of radio waves varies depending on their specific frequency. Lower frequencies tend to travel further and can penetrate solid objects more effectively, making them suitable for long-range communication and broadcasting. Higher frequencies have shorter wavelengths and are more directional, allowing for greater bandwidth and higher data transfer rates, which are essential for modern wireless services like Wi-Fi and 5G mobile networks.

The development and utilization of radio frequencies have revolutionized communication and various industries. From early wireless telegraphy to sophisticated satellite systems and advanced telecommunications, radio frequency technology plays a crucial role in our daily lives. Understanding radio frequency is fundamental to comprehending how many modern technologies function and how they interact with the environment. Regulations governing the use of radio frequencies are established by international bodies to prevent interference and ensure efficient spectrum allocation.
