RF Interference

RF interference from home, office, and medical equipment is a common challenge in wireless deployments.
When considering RF interference sources, remember that most cell/wireless phones and Bluetooth devices
only utilize the 2.4 GHz frequency. As such, they should not cause significant interference with wireless
networks operating in the 5 GHz frequency.
