government regulations.
3. Beacon interval
: Beacons are broadcast packets that are sent by a wireless
AP/router. The main purpose of beacon packet is let wireless clients know this AP
(SSID) when doing wireless network scan.
4. DTIM interval
: A DTIM is a countdown informing clients of the next window for
listening to broadcast and multicast messages. When the wireless router has
buffered broadcast or multicast messages for associated clients, it sends the next
DTIM with a DTIM Interval value.
5. RTS Threshold:
If an excessive number of wireless packet collision occurred, the
wireless performance will be affected. It can be improved by adjusting the
RTS/CTS (Request to Send/Clear to Send) threshold value.
6. Fragmentation
: Wireless frames can be divided into smaller units (fragments) to
improve performance in the presence of RF interference and at the limits of RF
coverage.
7. WMM Capable:
WMM can help control latency and jitter when transmitting
multimedia content over a wireless connection.
8. Short GI:
Time setting of Guard Interval between two Wi-Fi packets. Decrease
this time interval will increase Wi-Fi data throughput. But it may cause some
side-effects when the quality of Wi-Fi signal is not good. 800ns is the standard
time setting of GI.
9. TX Rate:
For WiFi transmit rate, you can choose “Best” for auto-adjustment
according to WiFi signal quality in your environment, or you can fix it in certain TX
rate. If you want to fix Tx rate at certain level, you need to set value of “
RF
Bandwidth
” as “HT20” or “HT40” instead of “Auto”. Please note the WiFi
connection may be dropped if you fix at a higher date rate but in a noisy (poor RF
signal quality) environment.
