The Total Cost of a Wireless Network: Page 6 of 19

Next, you require specific recommendations and estimates of the costs associated with the ongoing management, configuration and monitoring of the wireless infrastructure. That infrastructure has its own requirements--such as utilization monitoring and load balancing--that must be managed. In other words, what will it take to keep it up and running?

This cost estimate also should include WLAN management capabilities. Ongoing costs include support and maintenance fees for all components and labor costs, both of added staff that the integrator recommends as well as their own consulting staff--if you decide you need to keep them around.

The wireless integrator also must specify the ways in which the WLAN will be integrated with the wired network and how service will support the overall computing environment. Among issues to be addressed, the integrator must provide a solution to allow users to roam as seamlessly as possible between floors and IP subnets.

Because wireless devices radiate their signals, the perimeter of HealthPlex's network will become much more porous than it has been. Thus, the integrator must provide specific recommendations on what HealthPlex needs to do to ensure that the WLAN does not weaken the security of its network--with specific attention to the areas of authorization, authentication, encryption, wireless IDS/IPS and guest access to the Internet for visitors.

This WLAN project represents a substantial investment, so you need a "future-proofing" strategy to ensure that the WLAN remains viable. This includes long-term capacity planning, as well as software and firmware upgrades.
