支持for Dual 5 GHz Radio Mode

Starting fromArubaOS8.3.0.0,340 SeriesSeries access points provide dual 5GHzGigahertz.radio support. This feature is introduced for theAP-344andAP-345access points. In these AP models, by default, one radio operates in 5GHzGigahertz.mode and the other in the 2.4GHzGigahertz.mode.

The following points hold true when theDual 5GHz modeoption is enabled on340 Seriesaccess points:

Dual 5GHzGigahertz.mode is a feature that you can enable at the AP level.

Both radios operate in 5GHzGigahertz.bandBand refers to a specified range of frequencies of electromagnetic radiation.and use the same dot11a-radio-profile.

Both radios have the same Virtual APs that are allowed in the 5GHzGigahertz.mode.

TheSSIDsService Set Identifier. SSID is a name given to a WLAN and is used by the client to access a WLAN network.of both radios are same.

Both radios support802.11a802.11a provides specifications for wireless systems. Networks using 802.11a operate at radio frequencies in the 5 GHz band. The specification uses a modulation scheme known as orthogonal frequency-division multiplexing (OFDM) that is especially well suited to use in office settings. The maximum data transfer rate is 54 Mbps.,802.11n802.11n is a wireless networking standard to improve network throughput over the two previous standards, 802.11a and 802.11g. With 802.11n, there will be a significant increase in the maximum raw data rate from 54 Mbps to 600 Mbps with the use of four spatial streams at a channel width of 40 MHz.,802.11ac802.11ac is a wireless networking standard in the 802.11 family that provides high-throughput WLANs on the 5 GHz band.4x4:4SS 20/40/80/160MHzMegahertz(Max data rate of 1733MbpsMegabits per second).

The supported channels for the radios are within the prescribed Upper 5GHzGigahertz.channel range (5.470–5.850GHzGigahertz.) and Lower 5GHzGigahertz.通道范围(5.150 - -5.350GHzGigahertz.).

The middle 5GHzGigahertz.channel range is not available for the radios.

The APs support all forwarding modes—Tunnel, Decrypt Tunnel, Split, or Bridge—irrespective of the dual 5GHzGigahertz.模式是enabled or disabled.

AirMatch dynamically determines when the AP must operate in 5GHzGigahertz.mode or dualbandBand refers to a specified range of frequencies of electromagnetic radiation.mode, when theDual 5GHz modeoption is set toAutomatic. This feature is supported only onAP-345access points.

WhenDual 5GHz modeoption is enabled, the radios are not set to Air Monitor mode. The radios continue to operate in the AP mode.

IfARMAdaptive Radio Management. ARM dynamically monitors and adjusts the network to ensure that all users are allowed ready access. It enables full utilization of the available spectrum to support maximum number of users by intelligently choosing the best RF channel and transmit power for APs in their current RF environment.or AirMatch determines that due to limited channels, the AP (withDual 5GHz modeenabled) must be forced into Air Monitor mode, one of the radios is forced to go into the Air Monitor mode.

Depending on the Clarity client’s radiobandBand refers to a specified range of frequencies of electromagnetic radiation., the Clarity configuration is resent for the changed operation mode.

If a Mesh AP operates in 2.4GHzGigahertz., you cannot set it to operate in the dual 5GHzGigahertz.mode. This option is disabled for a Mesh AP.

During configuration push for a Mesh AP, theDual 5GHz modeoption is set to disabled (override).

MultiZone support is provided inArubaOS8.3.0.0 for the dual 5GHzGigahertz.feature.

The newDual 5GHz modeoption helps to change one of the radios dynamically from a 2.4GHzGigahertz.mode to a 5GHzGigahertz.radio mode. You can set this feature to enable, disable, or automatic mode by using the WebUI or theCLICommand-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions..
