Wireless Security Overview

Wireless security is vital to your network to protect wireless communication between wireless clients, access points and the wired network.

Wireless security methods available on the P-870HN-51D are data encryption, wireless client authentication, restricting access by device MAC address and hiding the P-870HN-51D identity.

The following figure shows the relative effectiveness of these wireless security methods available on your P-870HN-51D.
