Description
Enter the size of the Request to Send (RTS) threshold packet.
The RTS threshold is related to the transmission mechanism
(CSMA/CA or CSMA/CD) for the packets. If the packet size is equal to
or less than this threshold, the data frame is transmitted immediately; if
the packet size is larger than the specified value, the transmitting
station needs to send an RTS threshold packet to the receiving station,
and then should wait for the receiving station to return a Clear to Send
(CTS) packet before sending the actual packet data.
packets. Packets larger than the specified fragmentation length are
broken up into smaller packets before being transmitted. The
fragmentation length needs to be an even number.
Enter the time interval for each beacon transmission that allows the
access point to synchronize the wireless network.
Enter the maximum length of Aggregated MAC Protocol Data Unit
(AMPDU) packets. Larger aggregation lengths can lead to better
network performance. Aggregation is a mechanism used to achieve
higher throughput.
Select the On radio button to allow the aggregation of several MAC
frames into a single large frame to achieve higher throughput. Enabling
AMPDU can lead to better network performance. Select the Off radio
button to disable this option.
Select the On radio button to enable the Reduced Interframe Space
(RIFS) option to allow transmission of successive frames at different
transmit powers. Enabling RIFS can lead to better network
performance. Select the Off radio button to disable this option.
Enter the Delivery Traffic Indication Message (DTIM) or the data
beacon rate that you want to use. This sets the message period of the
beacon delivery traffic indication in multiples of beacon intervals.
Select one of the following radio buttons to specify the preamble type:
• Auto. Automatically handles both long and short preambles. A short
transmit preamble provides better performance. Auto is the default
setting.
• Long. Enables a long transmit preamble to provide a more reliable
connection or a slightly longer range.
