What type of interference is least likely to impact a wireless LAN?

Interference from wired networks is least likely to impact a wireless LAN. This is because wireless LANs operate using radio frequency signals that transmit data through the air, while wired networks use physical cables to transmit data. The distinction between these two mediums means that wired networks do not inherently interfere with the radio waves used by a wireless LAN.

In contrast, interference from microwaves, remote controls, and other wireless networks can significantly affect the performance and reliability of a wireless network. Microwaves can operate on similar frequencies to some wireless signals, leading to potential disruptions. Remote controls, particularly those using infrared or specific radio frequencies, may also introduce interference. Furthermore, other wireless networks operating on the same or overlapping frequencies can cause signal degradation or reduced bandwidth, making those types of interference a more critical concern for wireless LANs.
