Current Channel Read-only. The actual channel the ACS has assigned to the

Wireless AP radio. The Current Channel value and the Last

Requested Channel value may be different because the ACS

automatically assigns the best available channel to the Wireless

AP, ensuring that a Wireless AP’s radio is always operating on the

best available channel.

Last Requested Channel Read-only. The last wireless channel that you had selected to

communicate with the wireless devices.

Request New Channel Click the wireless channel you want the Wireless AP to use to

communicate with wireless devices.

Click Auto to request the ACS to search for a new channel for the

Wireless AP, using a channel selection algorithm. This forces the

Wireless AP to go through the auto-channel selection process

again.

Note: ACS in the 2.4GHz radio band with 40MHz channels is not

recommended due to severe co-channel interference.

Depending on the regulatory domain (based on country), some

channels may be restricted. The default value is based on North

America. For more information, see Appendix B.

Auto Tx Power Ctrl (ATPC) Select to enable ATPC. ATPC automatically adapts transmission

power signals according to the coverage provided by the Wireless

APs. After a period of time, the system will stabilize itself based on

the RF coverage of your Wireless APs. The APs should be part of

the same RF Domain to function properly.

Note: If you disable ATPC, you can still choose to maintain using

the current Tx power setting ATPC had established. If you elect to

maintain using the ATPC power setting, the displayed Current Tx

Power Level value becomes the new Max Tx Power value for the

Wireless AP.

Current Tx Power Level The actual Tx power level used by the Wireless AP radio.

Max Tx Power Click the maximum Tx power level to which the range of transmit

power can be adjusted: 0 to 24 dBm. Siemens recommends that

you select 24 dBm to use the entire range of potential Tx power.

Note: In reality, the lowest achievable power level is 5 dBm for the

Wireless 802.11n APs. If you assign a lower value, it will

automatically default to the lowest achievable level.

Min Tx Power If ATPC is enabled, click the minimum Tx power level to which the

range of transmit power can be adjusted. Siemens recommends

that you select the lowest value available to use the entire range

of potential Tx power.

Note: The Minimum Tx Power level is subject to the regulatory

compliance requirement for the selected country.
