•
Basic Rate — the set of data transfer rates that all the stations will be capable of using to
receive frames from a wireless medium.
•
Fragmentation Threshold—used to fragment packets which help improve performance in
the presence of radio frequency (RF) interference.
•
RTS Threshold (Request to Send Threshold) — determines the packet size of a
transmission through the use of the router to help control traffic flow.
•
DTIM Interval — sets the Wake-up interval for clients in power-saving mode.
•
Beacon Interval — a packet of information that is sent from a connected device to all other
devices where it announces its availability and readiness. A beacon interval is a period of
time (sent with the beacon) before sending the beacon again. The beacon interval may be
adjusted in milliseconds (ms).
•
Xpress Technology — a technology that utilizes standards based on frame bursting to
achieve higher throughput. With Xpress Technology enabled, aggregate throughput (the sum
of the individual throughput speeds of each client on the network) can improve by up to 25%
in 802.11g only networks and up to 75% in mixed networks comprised of 802.11g and
802.11b equipment.
•
54g Mode — 54g is a Broadcom Wi-Fi technology.
•
54g Protection — the 802.11g standards provide a protection method so 802.11g and
802.11b devices can co-exist in the same network without "speaking" at the same time. Do
not disable 54g Protection if there is a possibility that an 802.11b device may need to use
your wireless network. In Auto Mode, the wireless device will use RTS/CTS (Request to Send
/ Clear to Send) to improve 802.11g performance in mixed 802.11g/802.11b networks. Turn
protection off to maximize 802.11g throughput under most conditions.
•
Preamble Type — this information relates to wireless communication based
•
Transmit Power — select from 20%, 40%, 60%, 80% and 100%. The default value is 100%
but can be changed.
•
WMM (Wi-Fi Multimedia) — prioritizes traffic from different applications such as voice, audio
and video applications under different environments and conditions.
•
WMM No Acknowledgement — the acknowledgement policy used on the MAC level.
Enabling no-acknowledgement can result in efficient throughput but higher error rates in a
noisy Radio Frequency (RF) environment.
•
WMM APSD — APSD (Automatic Power Save Delivery). APSD manages radio usage for
battery-powered devices to allow battery life in certain conditions. APSD allows a longer
beacon interval until an application—VoIP for example—requiring a short packet exchange
interval starts. Only if the wireless client supports APSD does APSD affect radio usage and
battery life.
