WebJul 27, 2024 · Attenuation is a loss of signal strength measured in dB that reduces a connection’s maximum speed available due to the need for multiple repeat transmissions. Ultimately the attenuation you experience – and how it impacts your business – depends on the distance between you and your C/O. The further the distance, the lower your available ... WebShadowing. Shadowing is the effect that the received signal power fluctuates due to objects obstructing the propagation path between transmitter and receiver. These fluctuations are experienced on local-mean powers, that is, short-term averages to remove fluctuations due to multipath fading. Experiments reported by Egli in 1957 showed that, for ...
