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
