WEC8500/8050 Operation Manual Version 5.2Samsung Electronics America page 34 of 5331.4.4 Configuration of Multiple Sites Consisting of Headquarterand BranchesThe W-EP wireless LAN network environment usually consists of one headquarter andseveral 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 wirelessLAN AP is installed in a branch.In the hierarchical type, it is advantageous that each branch can use each different servicepolicy. However, the management in headquarter is complex and many low-capacity APCsmust 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 aremote place. The APC in headquarter provides a wireless LAN service in the headquarterbuilding and also provides a wireless LAN service to a remote W-EP wireless LAN APinstalled in a branch. As the APC in headquarter manages all the W-EP wireless LAN APsusing 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 belowfigure.Figure 15.
