telecommunications networks. It achieves higher speeds and supports
more users than most TDMA schemes through DS-CDMA channel
access method and the FDD duplexing method. Utilizing the same core
network as the 2G GSM networks deployed worldwide, it allows
dual-mode operation along with GSM/EDGE.
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 are several APs coexisting in the same area, it is recommended
that you configure a different channel for each AP to minimize the
interference between neighboring APs. For example, if 3 American-
standard APs (i.e. adopts channel 11) coexist in one area, you can setup
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: Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access
II (WPA2) are two security protocols and security certification programs
developed to secure wireless computer networks. The WPA protocol
implements the majority of the IEEE802.11i standard. Specifically, it
