 Chapter 6 Wireless LAN

NWA1000 Series User’s Guide

69

Preamble Type

Select 

Dynamic

 to have the AP automatically use short preamble when wireless adapters 

support it, otherwise the AP uses long preamble.

Select 

Long

 if you are unsure what preamble mode the wireless adapters support, and to 

provide more reliable communications in busy wireless networks. 

RTS/CTS 
Threshold

(Request To Send) The threshold (number of bytes) for enabling RTS/CTS handshake. 
Data with its frame size larger than this value will perform the RTS/CTS handshake. 
Setting this attribute to be larger than the maximum MSDU (MAC service data unit) size 
turns off the RTS/CTS handshake. Setting this attribute to its smallest value (1) turns on 
the RTS/CTS handshake. 

Extension 
Channel 
Protection Mode

You can use 

CTS to self 

or 

RTS-CTS

 protection mechanism to reduce conflicts with other 

wireless networks or hidden wireless clients. The throughput of 

RTS-CTS 

is much lower 

than 

CTS to self

. Using this mode may decrease your wireless performance.

A-MPDU 
Aggregation 

This field is available only when 

802.11n

, 

802.11b/g/n

, 

802.11a/n

 or

 802.11a/n/ac 

is selected as the 

Wireless Mode

. 

Select to enable A-MPDU aggregation.

Message Protocol Data Unit (MPDU) aggregation collects Ethernet frames along with their 
802.11n headers and wraps them in a 802.11n MAC header. This method is useful for 
increasing bandwidth throughput in environments that are prone to high error rates.

Short GI 

This field is available only when

 802.11n

, 

802.11b/g/n

, 

802.11a/n 

or

 802.11a/n/ac 

is selected as the 

Wireless Mode

. 

Select 

Enabled

 to use 

Short GI

 (Guard Interval). The guard interval is the gap 

introduced between data transmission from users in order to reduce interference. 
Reducing the GI increases data transfer rates but also increases interference. Increasing 
the GI reduces data transfer rates but also reduces interference.

MCS Rate

The 

MCS Rate

 table is available only when

 802.11n

, 

802.11b/g/n

 or 

802.11a/n 

or

 

802.11a/n/ac 

is selected

 

in the 

Wireless Mode 

field.

IEEE 802.11n supports many different data rates which are called MCS rates. MCS stands 
for Modulation and Coding Scheme. This is an 802.11n feature that increases the wireless 
network performance in terms of throughput. 

For each MCS Rate (0-15), select either 

Enabled

 to have the NWA use the data rate. 

Clear the 

Enabled 

check box if you do not want the NWA to use the data rate. 

Turn on the 

Auto

 option to have the NWA set the data rates automatically to optimize the 

throughput.

Note: You can set the NWA to use up to four MCS rates at a time.

Apply
