11b/g Wireless Outdoor Multi-Client Bridge/AP
Version 1.0

WPA Mode
: Select the
WPA / WPA2
from the drop-down list.
Cipher Type
: Select TKIP or AES as the cipher suite. The encryption algorithm used
to secure the data communication. TKIP. Use TKIP only. TKIP (Temporal Key
Integrity Protocol) provides per-packet key generation and is based on WEP. AES.
Use AES only. AES (Advanced Encryption Standard) is a very secure block based
encryption. Note that, if the bridge uses the AES option, the bridge can associate
with the access point only if the access point is also set to use only AES. TKIP and
AES. The bridge negotiates the cipher type with the access point, and uses AES
when available.
Group Key Update Interval
: Specify the number of seconds before the group key
used for broadcast and multicast data is changed.
Pre-Shared Key
: The key is entered as a pass-phrase of up to 63 alphanumeric
characters in ASCII (American Standard Code for Information Interchange) format at
both ends of the wireless connection. It cannot be shorter than eight characters,
although for proper security it needs to be of ample length and should not be a
commonly known phrase. This phrase is used to generate session keys that are
unique for each wireless client.

4.3.1.3 WPA
Enterprise
(Wi-Fi Protected Access & 802.1x)
Select the WPA-Enterprise radio button if your wireless network uses WPA
encryption. WPA (Wi-Fi Protected Access) was designed to improve upon the
security features of WEP (Wired Equivalent Privacy). The technology is designed to
work with existing Wi-Fi products that have been enabled with WEP. WPA provides
improved data encryption through the Temporal Integrity Protocol (TKIP), which
scrambles the keys using a hashing algorithm and by adding an integrity checking
feature which makes sure that keys haven’t been tampered with.
This option works with a RADIUS Server to authenticate wireless clients. Wireless
clients should have established the necessary credentials before attempting to
authenticate to the Server through this Gateway. Furthermore, it may be necessary
to configure the RADIUS Server to allow this Gateway to authenticate users.
