Since 802.11b/g WLANs are operating in the crowded 2.4-GHz IMS band with so many
competing devices (including 802.11b/g devices themselves), the following actions are
recommended in order to minimize or eliminate RF interference to 802.11b/g WLANs:
• Prior to installing an 802.11b WLAN, conduct a thorough RF survey of the WLAN site
to know all 2.4-GHz devices operating in the WiFi environment and the channels they
are using.
• Install 802.11b WLANs by setting the APs to non-overlapping channels 1, 6, and 11,
especially when more than one AP is needed.
• Try to avoid the use of HFSS devices in close proximity of an 802.11b WLAN to
minimize RF interference.
• If you have more than one 802.11b AP, adjust the transmit power levels on the APs to
minimize mutual interference between APs.
• Try to keep WLAN APs at a good physical distance to avoid mutual interference.
• Upgrade your WLAN to 802.11g or n standard
