• A user selects the Auto channel from the Wireless AP’s radio
configuration tabs.
• A user selects the Auto channel from the AP Multi-edit page.
• A Wireless AP detects radar on its current operating channel and it
employs ACS to select a new channel
• Auto Tx Power Control (ATPC) – ATPC guarantees your LAN a stable RF
environment by automatically adapting transmission power signals according
to the coverage provided by the Wireless APs. ATPC can be either enabled
or disabled.
Wireless APs and the sensor role
When an Wireless AP is assigned to the sensor role, its configuration data is
preserved on the HiPath Wireless Controller. The configuration data can only be
modified when the Wireless AP is switched back to the Wireless AP role.
In addition, if a Wireless AP is assigned to the sensor role, the 802.11b/g,
802.11a, and Static Configuration tabs are not visible.
Note: The HiPath Wireless Outdoor AP and the Wireless 802.11n AP cannot
work as a sensor; you cannot assign the sensor role to the HiPath Wireless
Outdoor AP or the Wireless 802.11n AP.
4.5.3.1 Modifying Wireless 802.11n AP 3610/3620 radio
properties
The Wireless 802.11n AP 3610/3620 is a 802.11n (draft)-compliant access point.
The following section discusses how to modify a Wireless 802.11n AP.
For information on how to modify a Wireless AP 2610/2620 or the HiPath
Wireless Outdoor AP, see Section 4.5.3.2, “Modifying Wireless AP 2610/2620
radio properties”, on page 106.
Channel bonding
Channel bonding improves the effective throughput of the wireless LAN. In
contrast to the Wireless AP 26xx which uses radio channel spacings that are only
20MHz wide, the Wireless 802.11n AP can use two channels at the same time to
create a 40MHz wide channel. To achieve a 40MHz channel width, the Wireless
802.11n AP employs channel bonding — two 20MHz channels at the same time.
The 40MHz channel width is achieved by bonding the primary channel (20MHz)
with an extension channel that is either 20MHz above (bonding up) or 20MHz
below (bonding down) of the primary channel.
Depending on the radio protocols, channel bonding can be predefined:
