Understanding spectrum: Radio frequency, optical fiber and modulation techniques, ET Telecom
Radio Frequency: RF communication primarily works by creating electromagnetic waves at a source and broadcasting them into the environment. These waves are then captured by a receiver and translated into usable information. However, this method's effectiveness is directly tied to the characteristics of the RF signals, such as frequency, power and modulation technique, which impact range, data speed and reliability.
