The Total Cost of a Wireless Network: Page 9 of 19

Controllers are priced by their capacity, based on the number of APs they can support simultaneously. According to the integrator, controller capacity can range from three to 300 APs, and pricing can run from $3,000 to $50,000 dollars per controller.

AP costs also vary based on capability, which accounts for the wide range of prices--from $200 to $900 per device. A Cisco AP with modular radios, external antenna ports, RF monitoring capabilities and locking mounts would list at $900, whereas a virtually disposable Trapeze single-radio AP would be closer to $200.

For HealthPlex Software, Portaro recommends two controllers for redundancy and 20 to 30 APs, for an estimated hardware cost of between $12,000 and $127,000. A more precise cost estimate would require further consultation to determine the right balance of price and capability.

Portaro assumes HealthPlex has network-wide authentication measures in place, including a RADIUS server and Active Directory. He may also identify other areas where authentication components must be installed.

The security picture includes the use of 802.1X authentication for network access, WPA2 clients with AES for wireless encryption and segregated VLANs for voice, data, video, guest access, and network management. Most controller-based systems already provide basic management capabilities for wireless IDS and IPS, using various software-based approaches to detect and contain rogue users or those attempting to spoof their way into your network.
