OBW (Occupied Bandwidth)

In the context of RF, which stands for radio frequency, OBW stands for Occupied Bandwidth. Occupied Bandwidth is the bandwidth containing 99% of the total integrated power of a signal, centered on the carrier frequency. It's an important parameter in RF communications as it defines the range of frequencies a signal occupies and is particularly crucial in ensuring that the transmission complies with regulatory requirements, minimizes interference with other signals, and efficiently uses the spectrum. By measuring and controlling the occupied bandwidth, communication systems can optimize performance and coexist with other systems operating in adjacent frequency bands.
