DESCRIPTIONS

 

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 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. This value can be set from 30ms to

 

 

1000ms. 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 100.

 

 

 

 

Output Power

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

 

 

density of APs in an area, decrease the output power of the NWA to

 

 

reduce interference with other APs. Select from 100% (Full

 

 

Power), 50%, 25%, 12.5% and Minimum. See the product

 

 

specifications for more information on your NWA’s output power.

 

 

Note: Reducing the output power also reduces the NWA’s

 

 

effective broadcast radius.

 

 

 

 

SSID Profile

The SSID (Service Set IDentifier) identifies the Service Set with

 

 

which a wireless station is associated. Wireless stations associating

 

 

to the access point (AP) must have the same SSID. Select an SSID

 

 

Profile from the drop-down list box.

 

 

Configure SSID profiles in the SSID screen (see Section 9.2 on page

 

 

147 for information on configuring SSID).

 

 

If you are configuring the NWA from a computer connected to the

 

 

wireless LAN and you change the NWA’s SSID or security settings,

 

 

you will lose your wireless connection when you press Apply to

 

 

confirm. You must then change the wireless settings of your

 

 

computer to match the NWA’s new settings.
