• Radio 2 — Channels can bond up or down as long as the band edge is not exceeded, but some

channels have predefined bonding directions.

Channel bonding is enabled by selecting the Channel Width on the Radio tabs. When selecting

Channel Width, the following options are available:

• 20MHz — Channel bonding is not enabled:

– 802.11n clients use the primary channel (20MHz)

– Non-802.11n clients, as well as beacons and multicasts, use the 802.11a/b/g radio

protocols.

• 40MHz — Channel bonding is enabled:

– 802.11n clients that support the 40MHz frequency can use 40MHz, 20MHz, or the 802.11a/

b/g radio protocols.

– 802.11n clients that do not support the 40MHz frequency can use 20MHz or the 802.11a/b/

g radio protocols.

– Non-802.11n clients, beacons, and multicasts use the 802.11a/b/g radio protocols.

– If the primary channel allows for both bonding types (up and down), you can select the

channel bonding type from the Channel Bonding drop-down list.

– If the primary channel allows for only one of the bonding types (up or down), that

channel bond type is displayed in the Channel Bonding drop-down list.

• Auto — Channel bonding is automatically enabled or disabled, switching between 20MHz

and 40MHz, depending on how busy the extension channel is. If the extension channel is busy

above a prescribed threshold percentage, which is defined in the 40MHz Channel Busy

Threshold box, channel bonding is disabled.

Channel Selection — Primary and Extension

The primary channel of the Wireless 802.11n AP is selected from the Request New Channel drop-

down list. If auto is selected, the ACS feature selects the primary channel. Depending on the

primary channel that is selected, channel bonding may be allowed: up or down.

Guard Interval

The guard intervals ensure that individual transmissions do not interfere with one another. The

Wireless 802.11n AP provides a shorter guard interval that increases the channel throughput.

When a 40MHz channel is used, you can select the guard interval to improve the channel

efficiency. The guard interval is selected from the Guard Interval drop-down list. Longer guard

periods reduce the channel efficiency.

Aggregate MSDU and MPDU

The Wireless 802.11n AP provides aggregate Mac Service Data Unit (MSDU) and aggregate Mac

Protocol Data Unit (MPDU) functionality, which combines multiple frames together into one

larger frame for a single delivery. This aggregation reduces the overhead of the transmission and

results in increased throughput. The aggregate methods are enabled and defined selected from the

Aggregate MSDUs and Aggregate MPDUs drop-down lists.

Antenna Selection

The W786C / W788C APs have 6 antennas: top left, middle, right and bottom left, middle, right.

The top antennas are connected to Radio 1; the bottom antennas are connected to Radio 2. For

details refer to the manual of your respective AP.
