802.11
A family of specifications developed by the IEEE for WLAN technology.
802.11b
An extension to 802.11 that applies to WLANS and provides 11 Mbps transmission rate in the 2.4GHz band.
802.11b use only DSSS.
802.11g
An extension to 802.11 that applies to WLANS and provides 54 Mbps transmission rate in the 2.4 GHz band.
802.11g use OFDM and is backward compatible with 802.11b.
Ad-hoc
Under this mode, any two wireless stations can communicate with each other directly, each station contention
public wireless channel. The advantage is build network conveniently, lower charge, and stabilization. The
disadvantage is that when user's station is too many, it will bring down the capability of Internet because each
station contention public wireless channel. At the same time, each station need to be connected directly, the
layout of Internet will be bounded sometimes. Furthermore, it can't access Internet. So this configuration only
can be used when the users are less.
AP
Access Point, A communication hub for wireless device users to connect to a wired LAN.
BBP
Baseband Processor The processor that handles the original band of frequencies of a signal before it is
modulated for transmission at a higher frequency.
Bridging
Bridging, provide path between two or more net section or subnet, these subnet have the same address and
topological structural. The device which bring off bridging called bridge, some station can use bridge to
broadcast message to other station, so bridge is a device which can connect net section's two port or more
port. And bridge also can divide the busy net into two section, reduce the traffic of each section to improve
capability. It can filter net broadcasting message, only allow the communication message get to another net
by bridge.
