nodes. This is accomplished by attaching an Access Point to the
wired LAN. This allows the wireless clients to access the net-
work resources.

For larger environments, RangeLAN2 products support the ability
to roam from one wireless cell to another while maintaining the
same network connection. The Access Points establish coverage
areas or cells similar in concept to those of a cellular phone
network. The mobile clients will connect to any Access Point that
is within range.
