As I've been discussing lately, radio frequency (RF) interference causes lower throughput in wireless LANs (WLANs). It's important that you learn as much as possible about what causes interference and what to do to minimize its impacts in order to maximize performance. Here we'll focus on the interference generated by 2.4GHz cordless phones.

Radio frequency (RF) interference causes wireless clients and access points to hold off transmitting, which causes delay and lower throughput. This resulting decrease in performance can make browsing websites and downloading files sluggish. In cases where interfering signals are strong enough, the wireless clients may not be able to access the LAN at all for an indefinite period of time. This is rare, but possible.

RF interference is still plaguing wireless LAN deployments. Many companies have gotten by without any problems, but some have installations that don't operate as well as planned. The perils of interfering signals from external RF sources are often the culprit. As a result, it's important that you're fully aware of RF interference impact and avoidance techniques.
