■ Smart Roaming for 802.11b/g
When a client (slave) moves from an area of an access point AP-1 to that of AP-2 and radio intensity
decreases (to about 14 or less), scanning of received channels is automatically started and a channel for
roaming is selected.
If no channel is found that is better in communication quality than the current channel, scanning is restarted
for 13CHs. (11CHs in United States)

Follow instructions below for stable communication:
• Operate under a clean environment without cross talk as long as possible.
• Install antennas so that there is a direct line of sight between them.
• Install communication ranges of access points so that they should overlap as long as possible.
Install access points with an interval of about 30 to 40m, as a guideline.
