Solution 2: Survivable Wireless Networking

Problem: Need for Survivable Mobility

and Network Services

A public high school has a network of 400 to 500 wired clients, including PCs,

laptops, printers and phones. Currently, Ethernet ports offer the only means

of access to the network, which provides little flexibility or mobility. The

school district would like to deploy a wireless solution at the high school that

is similar to wireless solutions that it has deployed elsewhere. However, a

manageable, secure wireless solution requires support from services that the

district typically deploys at the central district office only. For example, users

should log in to the wireless network through a Web portal using their domain

credentials. If the branch wireless devices cannot reach the central office Web

server and Network Policy Server (NPS), users will not be able to log in.

This problem highlights an existing issue: users at the high school must access

all network services over a WAN link to the central district office, making a

WAN link failure catastrophic.
