RF, or radio frequency, refers to the electromagnetic waves used for wireless communication. These waves typically range from 3 kHz to 300 GHz and are essential for various technologies, including cell phones, Wi-Fi, and television broadcasts. RF signals can travel through the air and can be modulated to carry information over long distances. In addition to communication, RF is also used in medical applications like RF ablation, which treats certain medical conditions by using heat generated from RF energy. The versatility of RF technology makes it crucial in both everyday life and specialized fields, enabling seamless connectivity and innovative solutions.
