Cisco Unified Wireless Networks Architecture (CUWN)

By Edward Tetz

Cisco has released information on the Cisco Unified Wireless Network (CUWN), which is less a product than it is a methodology and an integrated use of existing products. The unified part of this solution is that it incorporates a standard management methodology and goal across all the products that Cisco provides for both wired and wireless data communication, with data security in the front of all development thoughts.

In today’s technology market, the driving force behind mobile computing is actually mobile computer users. These users find it more and more convenient to be able to use their computing devices wherever they need to do a task. The more places that they can use their devices, the more places they want to be able to use them.

The more they talk to other mobile users in their travels, the more ways they find out they can use their devices — as well as how they cannot use them.

This push for more mobility while maintaining corporate accessibility gives corporate IT staff members a challenge in that they are typically concerned with the integrity, safety, and security of corporate data; allowing users in an ever-widening geographical area to have access to this data in ever-increasing new ways goes against the typical goals of corporate IT staff, which is to keep data as private as possible.

So the CUWN takes data from a client through wireless access points and wired infrastructure to the servers or devices that will ultimately hold the data. As such, CUWN makes use of networking devices at all levels of the process, and Cisco offers tools to allow central management of all these devices through a series of management tools.

The Cisco Unified Wireless Network uses some or all the following components:

  • Cisco Wireless Control System (WCS)

  • Cisco WCS Navigator

  • Cisco Wireless LAN Controller (WLC)

  • Cisco Wireless LAN Controller Module (WLCM)

  • Cisco Wireless Services Module (WiSM)

  • Cisco Catalyst 3750G Integrated Wireless LAN Controller

  • Cisco Controller-Based or Lightweight Access Point (LWAP)

  • Cisco Aironet Wireless Bridge

  • Cisco Aironet 1500 Series Controller-Based or Lightweight Outdoor Mesh Access Points

  • Cisco Client Devices
