Total Controller Costs
Cisco Wireless LAN Controllers are another component of the Cisco Unified Wireless Network and
deliver services simultaneously to all access points. To assess the costs of controller
implementation, Forrester assumes that the composite organization distributes the following access
point breakdown across its four campuses: 500, 100, 100, and 50. We assume that the composite
organization uses two types of controllers: WiSM and 4400-100 series.

organization uses two types of controllers: WiSM and 4400-100 series.
The WiSM and 4400-100 controller can manage up to 300, and 100 access points, respectively.
With an average list price of $45,995 for WiSM and $34,995 for 4400-100 controllers, we applied
the following controller distribution: two WiSMs to manage the 500 access point campus, three
4400-100 controllers for campuses with access points varying from 50 to 100, and one additional
WiSM controller for backup (n+1 environment); allowing additional capacity to accommodate future
access point expansion. Table 5 illustrates this calculation.

WCS Licensing Costs
Cisco WCS allows network managers to design, control, and monitor the wireless network from a
centralized location. Cisco offers licenses for 100, 500, 1000, 2500, 10000, and 50000 access
points. We chose the option to purchase one license for 1000 access point for the list price of
$46,950 to accommodate any future expansion. The 2500, 10000, and 50000 enterprise licenses
also include WCS Navigator, a utility to manage multiple WCS management stations. Table 6
demonstrates this calculation.
