use Long Preamble if needed to communicate with this kind
of devices.
Packet-OVERDRIVE TX
Burst This feature can enhance the performance in data
transmission about 40%* more (by checking Tx Burst). It is
active only when both sides of Access Point and Station (in
wireless client) invoke this function at the same time. That
is, the wireless client must support this feature and invoke
the function, too.
Note: Vigor N61 wireless adapter supports this function.
Therefore, you can use and install it into your PC for
matching with Packet-OVERDRIVE (refer to the following
picture of Vigor N61 wireless utility window, choose Enable
for TxBURST on the tab of Option).
TX Power Set the power percentage for transmission signal of access
point. The greater the value is, the higher intensity of the
signal will be.
WMM Capable WMM is an abbreviation of Wi-Fi Multimedia. It defines the
priority levels for four access categories derived from 802.1d
(prioritization tabs). The categories are designed with
specific types of traffic, voice, video, best effort and low
priority data. There are four accessing categories - AC_BE ,
AC_BK, AC_VI and AC_VO for WMM.
To apply WMM parameters for wireless data transmission,
please click the Enable radio button.
APSD Capable APSD (automatic power-save delivery) is an enhancement
over the power-save mechanisms supported by Wi-Fi
networks. It allows devices to take more time in sleeping
state and consume less power to improve the performance
by minimizing transmission latency.
The default setting is Disable.
Rate Adaptation Algorithm Wireless transmission rate is adapted dynamically. Usually,
performance of “new” algorithm is better than “old”.
Fragment Length
(256 – 2346) Set the Fragment threshold. Do not modify default value if
you don’t know what it is, default value is 2346.
RTS Threshold (1 – 2347) Minimize the collision (unit is bytes) between hidden stations
to improve wireless performance.
Set the RTS threshold. Do not modify default value if you
don’t know what it is, default value is 2347.
