Association Control

If the number of currently associated wireless clients exceeds the value specified in the

Max

number of clients

setting, no more wireless clients can associate with the AWK-1100. If the

traffic load of the AWK-1100 exceeds the load specified in the

Block clients if traffic load

exceeds

setting, no more wireless clients can associate with the AWK-1100.

AP Load Balancing

Several APs can form a load-balancing group if they are set with the same Group ID. The
load-balancing policy can be by

Number of Users

or by

Traffic Load

.

If the

by-number-of-users

policy is selected, a new wireless user can only associate with an AP

that has the smallest number of associated wireless users in the group. On the other hand, if the

by-traffic-load policy

is selected, a new wireless user can only associate with an AP that has the

least traffic load in the group.

AP 1

WDS

Traditionally, access points are connected by Ethernet. By using a Wireless Distribution System
(WDS), APs can communicate with one another wirelessly. For example, AP 2 acts as an access
point for the notebook computers and it forwards packets sent from the notebook computers to AP
1 through WDS. Then, AP 1 forwards the packets to the Ethernet LAN. Packets destined for the
notebook computers follow a reverse path from the Ethernet LAN through the APs to the notebook
computers. In this way, AP 2 plays a role of “AP repeater.”
