1.4.4 Configuration of Multiple Sites Consisting of Headquarter
and Branches
The W-EP wireless LAN network environment usually consists of one headquarter and
several branches.
In this case, there are two types of network configuration.

Hierarchical type: A APC is installed in a branch as well as headquarter.

Branch AP type: A APC is installed only in a headquarter and only a W-EP wireless
LAN AP is installed in a branch.
In the hierarchical type, it is advantageous that each branch can use each different service
policy. However, the management in headquarter is complex and many low-capacity APCs
must be installed, so the branch AP type is commonly used.
The branch AP type has the same structure as a basic W-EP wireless LAN configuration.
A single difference is that a W-EP wireless LAN AP installed in a branch is located at a
remote place. The APC in headquarter provides a wireless LAN service in the headquarter
building and also provides a wireless LAN service to a remote W-EP wireless LAN AP
installed in a branch. As the APC in headquarter manages all the W-EP wireless LAN APs
using the same policy, it is easy to use and cost-effective.
An example of service configuration diagram for the branch AP type is shown in the below
figure.
