Setting Default Device Type Description

Transmit Power

Reduction

0 Proxim

Transmit Power Reduction determines the APs transmit

power. The max transmit power is reduced by the number of

decibels specified.

Channel 6 All

Represents the AP’s current RF channel setting. The

number relates to the center frequency output by the AP’s

RF synthesizer.

Contiguous APs should be set to different channels to

minimize ‘crosstalk,’ which occurs when the signals from

APs overlap and interfere with each other. This RF

interference negatively influences WLAN performance.

802.11b’s 2.4-GHz range has a total bandwidth of 80-MHz,

separated into 11 center channels. Of these channels, only

3 are non-overlapping (1, 6, and 11). In the United States,

most organizations use only these non-overlapping

channels.

(802.11g)

Determines the power level of radio transmission.

Government regulations define the highest allowable power

level for radio devices. This setting must conform to

established standards for the country in which you use the

device. You can increase the coverage radius of the access

point by increasing the Transmit Power Level. However,

while this increases the zone of coverage, it also makes it

more likely that the AP will interfere with neighboring APs.

Supported values are: Cisco (100mW, 50mW, 30mW,

20mW, 5mW, 1mW) Symbol (Full or 50mW, 30mW, 15mW,

5mW, 1mW)

Radio Enabled Yes All

The Radio Enabled option allows you to disable the radio's

ability to transmit or receive data while still maintaining

Ethernet connectivity to the network. AirWave will still

monitor the Ethernet page and ensure the AP stays online.

Customers typically use this option to temporarily disable

wireless access in particular locations.

This setting can be scheduled at an AP level or Group level.

NOTE: You cannot disable radios unless rogue scanning is

disabled in Groups > Radio.

Use DHCP Yes All

If enabled, the AP will be assigned a new IP address using

DHCP. If disabled, the AP will use a static IP address. For

improved security and manageability, disable DHCP and

using static IP addresses.

LAN IP None All

The IP Address of the AP Ethernet interface. If One-to-One

NAT is enabled, AirWave will communicate with the AP on a

different address (the IP Address defined in the Device

Communication section).

If DHCP is enabled, the current assigned address will

appear grayed out and the field cannot be updated in this

area.
