the function, too.

Preamble Type - This option is to define the length of the

sync field in an 802.11 packet. Most modern wireless

network uses short preamble with 56 bit sync field instead

of long preamble with 128 bit sync field. However, some

original 11b wireless network devices only support long

preamble.

Operation Mode - Mixed Mode allows the router to

transmit data with the ways supported in both 802.11a/b/g

and 802.11n standards. However, the entire wireless

transmission will be slowed down if 802.11g or 802.11b

wireless client is connected. Green Field allows the router to

get the highest throughput. Such mode can make the data

transmission happening between 11n systems only. In

addition, it does not have protection mechanism to avoid the

conflict with neighboring devices of 802.11a/b/g.

Channel Bandwidth - The router can use 20Mhz for data

transmission and receiving between the AP and the stations.

Or, it can use 20Mhz or 40Mhz for data transmission and

receiving according to the station capability. Such channel

can increase the performance for data transit.

Guard Interval - It is to assure the safety of propagation

delays and reflections for the sensitive digital data. If you

choose auto as guard interval, the AP router will choose

short guard interval (increasing the wireless performance) or

long guard interval for data transmit based on the station

capability.

Aggregation MSDU - Aggregation MSDU can

combine

frames with different sizes. It is used for improving MAC

layer’s performance for some brand’s clients. The default

setting is Enable.

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.
