WEP 64 (40-bit key)
WEP 64 (40-bit key)
Wired Equivalency Privacy (WEP) uses a key, or string of case-sensitive characters, to
encrypt and decrypt data packets transmitted between a mobile unit (MU) and the WS 2000
Wireless Switch. The administrator configures mobile units (MUs) and the WS 2000
Wireless Switch to use the same key.
WEP encrypts the wireless transmissions, but still allows communication among compatible
wireless LAN clients and MUs from third-party manufacturers that are 802.11b certified.
40-bit Shared Key requires encryption be set up in one of the following ways:
• String: For use only with other Symbol Technologies wireless LAN devices, an
encryption string is a case-sensitive string of characters between 6 and 30 characters
long.
• Shared keys: Hexadecimal keys are sequences of hexadecimal digits arranged into four
keys. A hexadecimal digit could be a letter from A to F or a number from 0 to 9. This
type of encryption is compatible with equipment from other manufacturers that use Wi-
Fi certified 40-bit encryption.
WEP 128 (104-bit Key)
Wired Equivalency Privacy (WEP) uses a key, or string of case-sensitive characters, to
encrypt and decrypt data packets transmitted between a mobile unit (MU) and the WS 2000
Wireless Switch. The administrator configures the MU and switch to use the same key. 104-
bit Shared Key provides a higher level of security than the 40-bit Shared Key option and
uses a more complicated encryption scheme.
WEP encrypts the wireless transmissions, but still allows communication among compatible
wireless LAN clients and MUs from third-party manufacturers that are 802.11b certified.

802.1x with RADIUS Authentication
RADIUS is a client/server protocol and software that enables remote access servers to
communicate with a central server to authenticate RADIUS-enabled mobile units (MUs)
and authorize their access to the requested system or service.
When an MU authenticates with a WS 2000 Wireless Switch through an Access Port, the
switch initially performs RADIUS authentication, even though the RADIUS server exists as
a separate entity on the wired LAN. This RADIUS server maintains user profiles in a
central database that all remote servers can share. This centralized location provides better
security by using a policy-based implementation through a single administered network
point.
The RADIUS server on the wired LAN communicates with the WS 2000 Wireless Switch
RADIUS client, passing authentication information from the MU. A successful negotiation
authenticates the MU.
