Chapter 2 Cisco Unified Wireless Technology and Architecture
Components
Components
There are three primary components that make up Cisco’s Unified Wireless Architecture: the
Lightweight APs, the WLC, and the WCS. This section describes the AP and WLC product options.
Lightweight APs, the WLC, and the WCS. This section describes the AP and WLC product options.
The Cisco WCS is an optional network component that works in conjunction with Cisco Aironet
Lightweight APs, Cisco wireless LAN controllers and the Cisco Wireless Location Appliance. With
Cisco WCS, network administrators have a single solution for RF prediction, policy provisioning,
network optimization, troubleshooting, user tracking, security monitoring, and wireless LAN systems
management. Robust graphical interfaces make wireless LAN deployment and operations simple and
cost-effective. Detailed trending and analysis reports make Cisco WCS vital to ongoing network
operations. More information on Cisco WCS can be found at the following URls:

WLCs
For convenience, this document refers to all Cisco Unified Wireless controllers as WLCs due to the
general uniformity and commonality of features across all of Cisco’s WLC platforms.
general uniformity and commonality of features across all of Cisco’s WLC platforms.
The following summarizes the various Cisco Unified Wireless WLCs and their features:
•
2106—Is a standalone WLC that supports up to six APs, with eight Fast Ethernet interfaces. Two of
the Fast Ethernet interfaces can be used to power (802.3af) directly connected APs. The interface
can be configured as dot1q trunks to provide connection into the wired network. The 2106 is ideal
for a small-to-medium size offices, where an H-REAP would otherwise be unsuitable because of the
number of users, WAN requirements, and/or client roaming requirements.

•
4402—Is a standalone WLC that supports either 12, 25, or 50 APs. It comes with two SFP-based
Gigabit Ethernet ports that can be configured as dot1q trunks to provide connection into the wired
network, or the Gigabit ports can be link-aggregated to provide an EtherChannel connection to the
switched network. This is ideal for medium-size offices or buildings.

•
4404—Is a standalone WLC that supports 100 APs. It comes with four SFP-based Gigabit Ethernet
ports that can be configured as dot1q trunks to provide connection into the wired network. The
Gigabit ports can be link aggregated to provide an EtherChannel connection to the switched
network. This is ideal for large offices, buildings, and even a small campus.

WLCM—The WLC module is specifically designed for Cisco’s Integrated Service Router (ISR)
series. It’s currently available in a 6, 8 or 12 AP version. The WLCM appears as an interface on the
ISR router that can be configured as a dot1q trunk to provide a routed connectivity to the wired
network. This is ideal for small-to-medium size offices requiring an integrated solution.

•
WS-C3750G—Is a WLC that supports either 25 or 50 APs that comes integrated with the Catalyst
3750 switch. The WLC’s backplane connections appear as two Gig Ethernet ports, that can be
configured separately as dot1q trunks to provide connection into the 3750. Or, the Gig ports can be
link aggregated to provide a single EtherChannel connection to the 3750. Because the WLC is
integrated directly it has access to all of the advanced routing and switching features available in the
3750 stackable switch. It is ideal for medium-size offices or buildings. The ‘50 AP’ version can scale
up to 200 APs when four 3750s are stacked together as a virtual switch.
