When providing a wireless solution it is important to select scaleable products that embrace all the current wireless standards to future proof the entire network. The implementation must also be secure with the data encrypted and the users authenticated.

Progressive Networks have built many Cisco based wireless networks for our customers each addressing individual requirements. The solution below highlights a typical example of one of these designs which takes advantage of all the various security elements required to implement a secure wireless network. These features include:

• Encryption through VPN Tunnels terminating on either a Firewall or VPN concentrator.
• User authentication using RADIUS through a Windows Domain or a One Time Password (OTP) system such as SecurID.
• Wireless bridges to offer cost effective connections to remote buildings and offices.

Wireless networks have two main applications as follows:

• Building to building communications
• Support of roaming laptops/PDAs around the office and campus.
