NoiseSource¶

Package: inet.physicallayer.wireless.noise

compound module NoiseSource

A network node that generates periodic noise transmissions that can interfere with wireless communications. Alternates between sleep and transmission states based on configurable intervals. Uses a NoiseTransmitter to create noise signals with specified duration, frequency, bandwidth, and power parameters. Useful for testing protocol robustness against interference in wireless networks.
