Which type of system is generally most impacted by Radio Frequency Interference (RFI)?

Wireless systems are particularly susceptible to Radio Frequency Interference (RFI) because they rely on the transmission of data over radio waves. RFI occurs when unwanted radio frequency signals disrupt the communication between devices. Since wireless systems operate in the same frequency ranges as many other electronic devices, they can easily pick up noise or interference from nearby sources, such as mobile phones, microwaves, and other wireless networks.

On the other hand, wired systems transmit information through physical cables, which helps shield them from external radio frequency signals, making them less vulnerable to RFI. Optical systems, which use light to transmit data, also do not experience RFI in the same way since they operate on completely different principles. Parallel systems, typically referring to the arrangement of components rather than the method of data transmission, do not specifically relate to susceptibility to RFI either. Therefore, the nature of wireless communication makes it the most impacted by RFI.
