DESCRIPTION

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 to reduce

 

interference with other APs. Select one of the following 100%(Full

 

Power), 50%, 25%, 12.5% or 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.

 

 

Rates Configuration

This section controls the data rates permitted for clients.

 

For each Rate, select an option from the Configuration list. The

 

options are:

 

• Basic (1~11 Mbps only): Clients can always connect to the

 

access point at this speed.

 

• Optional: Clients can connect to the access point at this speed,

 

when permitted to do so by the AP.

 

• Disabled: Clients cannot connect to the access point at this

 

speed.

 

 

MCS Table

The MCS Rate table is available only when 802.11n/g or

 

802.11n/a is selected as the 802.11 Radio Mode.

 

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 Enable (default) to have

 

the NWA use the data rate. Select Disable if you do not want the

 

NWA to use the data rate.
