Netgear WC7520 - ProSafe 20-AP Wireless Controller Manual De Referência

Optionally, you can override the channel and transmission power for individual access 
points.

RTS Threshold (0-2347)

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.

Fragmentation Length (256-2346) Enter the size that specifies the maximum fragmentation length for 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.

Beacon Interval (100-1000)

Enter the time interval for each beacon transmission that allows the 
access point to synchronize the wireless network.

Aggregation Length (1024-65535)

 

(802.11n only)

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.

AMPDU

 

(802.11n only)

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.

RIFS Transmission 

 

(802.11n only)

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.

DTIM Interval (1-255)

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. 

Preamble Type 

 

(802.11b/bg only)

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.
