W-CDMA
W-CDMA (Wideband Code Division Multiple Access), also known as
CDMA Direct Spread, is found in 3G mobile 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. Your
network's SSID should be unique to your network. A wireless client
device needs to know a wireless network's SSID in order to connect
