Radio Frequency Interference (RFI) is important for radio telescopes because of the environment conditions are the factors in determining the telescope's performance. For example, telecommunication signals and wireless technology can be more than 15 orders stronger than brightest radio sources. Strong interference may saturate the receiver system, where the response is no longer in the linear regime, and astronomers can no longer put the astronomical information to use. Therefore, RFI is important for identifying interference within the area and for preventing interference with radio telescopes.
