Enable A-MPDU

Aggregation

Select this 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.

A-MPDU Limit Enter the maximum frame size to be aggregated.

A-MPDU

Subframe

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

MSDU

Aggregation

Select this to enable A-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

Threshold

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

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

Threshold

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

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

sent. Enter an even number between 256 and 2346.

Beacon

Interval

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

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.
