DESCRIPTION

Enable A-MPDU

Select this to enable A-MPDU aggregation.

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.

 

 

A-MPDU Limit

Enter the maximum frame size to be aggregated.

 

 

A-MPDU

Enter the maximum number of frames to be aggregated each time.

Subframe

Select this to enable A-MSDU aggregation.

MSDU

 

Aggregation

Mac Service Data Unit (MSDU) aggregation collects Ethernet frames

 

without any of their 802.11n headers and wraps the header-less

 

payload in a single 802.11n MAC header. This method is useful for

 

increasing bandwidth throughput. It is also more efficient than A-

 

MPDU except in environments that are prone to high error rates.

 

 

A-MSDU Limit

Enter the maximum frame size to be aggregated.

 

 

RTS/CTS

Use RTS/CTS to reduce data collisions on the wireless network if you

Threshold

have wireless clients that are associated with the same AP but out of

 

range of one another. When enabled, a wireless client sends an RTS

 

(Request To Send) and then waits for a CTS (Clear To Send) before it

 

transmits. This stops wireless clients from transmitting packets at the

 

same time (and causing data collisions).

 

A wireless client sends an RTS for all packets larger than the number

 

(of bytes) that you enter here. Set the RTS/CTS equal to or higher

 

than the fragmentation threshold to turn RTS/CTS off.

 

 

Fragmentation

The threshold (number of bytes) for the fragmentation boundary for

Threshold

directed messages. It is the maximum data fragment size that can be

 

sent. Enter an even number between 256 and 2346.

 

 

Beacon

When a wirelessly networked device sends a beacon, it includes with

Interval

it a beacon interval. This specifies the time period before the device

 

sends the beacon again. The interval tells receiving devices on the

 

network how long they can wait in low-power mode before waking up

 

to handle the beacon. A high value helps save current consumption

 

of the access point.

 

 

DTIM

Delivery Traffic Indication Message (DTIM) is the time period after

 

which broadcast and multicast packets are transmitted to mobile

 

clients in the Active Power Management mode. A high DTIM value

 

can cause clients to lose connectivity with the network. This value

 

can be set from 1 to 255.

 

 

Output Power

Set the output power of the AP in this field. If there is a high density

 

of APs in an area, decrease the output power of the NWA5160N to

 

reduce interference with other APs. Select one of the following

 

100%(Full Power), 50%, 25%, or 12.5%. See the product

 

specifications for more information on your NWA3000-N series AP’s

 

output power.

 

Note: Reducing the output power also reduces the NWA3000-N

 

series AP’s effective broadcast radius.
