Appendix 1 Glossary
Channel
A communication channel, also known as channel, refers either to a physical
transmission medium such as a wire or to a logical connection over a
multiplexed medium such as a radio channel. It is used to transfer an
information signal, such as a digital bit stream, from one or more transmitters
to one or more receivers. If there is only one AP in the range, select any
channel you like. The default is
Auto
.
If there are several APs coexisting in the same area, it is advisable that you
select a different channel for each AP to operate on, minimizing the
interference between neighboring APs. For example, if 3 American- standard
APs coexist in one area, you can set their channels respectively to 1, 6 and
11 to avoid mutual interference.
SSID
Service set identifier (SSID) is used to identify a particular 802.11 wireless
LAN. It is the name of a specific wireless network. To let your wireless
network adapter roam among different APs, you must set all APs’ SSID to the
same name.
WPA/WPA2
The WPA protocol implements the majority of the IEEE 802.11i standard. It
enhances data encryption through the Temporal Key Integrity Protocol (TKIP)
which is a 128-bit per-packet key, meaning that it dynamically generates a
new key for each packet. WPA also includes a message integrity check
feature to prevent data packets from being hampered with. Only authorized
network users can access the wireless network. The later WPA2 protocol
features compliance with the full IEEE 802.11i standard and uses Advanced
Encryption Standard (AES) in addition to TKIP encryption protocol to
guarantee better security than that provided by WEP or WPA. Currently, WPA
is supported by Windows XP SP1.
