Something very useful for Administrators.

If you have many remote offices or branches, you may be concerned about the number of wireless LAN controllers you need to support your Cisco Unified Wireless Network. Deploying a controller in each office to configure and control your access points may be costly and difficult to manage.
In this scenario, you may want to use Cisco’s Hybrid Remote Edge Access Point (H-REAP) solution, which allows you to manage the access points in your remote locations from a single location through your WAN, without requiring a wireless LAN controller in every office.
H-REAP is supported with the following hardware:

• 1130AG, 1240AG, 1250, and AP801 access points
• 2100 and 4400 series controllers
• Catalyst 3750G Integrated Wireless LAN Controller

Switch

• Cisco WiSM
• Controller Network Module for Integrated Services

Routers
To find out whether H-REAP is an appropriate solution for your needs, you may want to consult the H-Reap Design and Deployment Guide at the following address:
