Explain why the statement "The network seems to be working OK so there must not be any RF interference." might be considered a wireless ‘myth'.

What will be an ideal response?


Because the IEEE 802.11 protocol is designed to resist interference to a degree, it may not always be apparent that RF interference is impacting the network. For example, when a wireless device senses an interference burst occurring before it has started its own transmission, it will wait on transmitting until the interference is finished. Yet if the interference burst starts in the middle of a transmission, so that an acknowledgement packet is not received, it will cause the transmitter to resend the entire packet. This can reduce the throughput of a WLAN and can be difficult to diagnose.
