Security
NONE
disables any 802.11 encryption or security authentication mechanisms.
WEP
(Wired Equivalent Privacy) is a wireless encryption protocol that scrambles wireless signals
allowing for greater security in the wireless network. If WEP/Encryption is required at this site, you
must configure each WT to correspond with the encryption protocol set up in the access points. Select
the entries from the options below to enable the WT to acquire the system.
Set each of these options to match exactly the settings in your APs.
Encryption codes display as they are entered. For security reasons, codes
will not display when a user returns to the Admin menu, Encryption
options.
Note that WEP may be set to “optional” at the AP if there are wireless
devices in use that do not have WEP capability. All wireless devices must
be upgraded to WEP capability for a fully secured WEP environment.

Cisco FSR
(Fast Secure Roaming) is a proprietary security mechanism devised by Cisco Systems to
overcome some shortcomings in the 802.11 Standard WEP encryption, without impacting the ability of
the WTs to roam from one AP to another with seamless voice. Cisco FSR requires advanced
configuration of the Cisco access points in your site. See your Cisco representative for detailed
