BG protected mode -- BG protected mode is a kind of self-adjusting
mechanism which could maintain the bandwidth to balance the transmission rate among
clients.
Beacon interval -- Beacon is a small data package for AP to synchronize wireless network.
Beacon interval is the time interval of AP sending two beacons.
DTIM -- Delivery Traffic Indication Map. DTIM is used for informing the client that multicast
or broadcast data caching on AP would be immediately transmitted after beacon frame.
AP will regularly detect caching data according to DTIM value. For example, 1 indicates
caching data needs detecting after each beacon.
Fragment threshold -- Fragment threshold value determines the size of the data package
for fragmentation (how many times a data block will be fragmented). This value could be
set smaller in an environment with unstable traffic or serious interference. It could help to
improve network performance.
RTS threshold -- RTS (Request to Send) threshold value determines the size of the data
package for AP to send a RTS clean-up channel before sending data. Lower RTS threshold
value works better if there are many, a few or even one connected clients or clients are
quite far away.
TX power -- Transmitted power allows to adjust the effective range and network coverage of
RF. For example, 80 could be input to adjust if the transmitted power of RF needs adjusting
to be 80% of the rated power.
Short Preamble -- It is the performance parameter of 802.11 BG mode of which some early
802.11b clients may not support though. This parameter could be used if this kind of client
does not exist in the network.
