Description
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).
Note: * means the real transmission rate depends on the
environment of the network.
