Radio Resource
Management
Radio Resource Measurement (RRM) mode requires the Wireless System to send
additional information in beacons, probe responses, and association responses.
Enable or disable the support for radio resource measurement feature in the AP
profile. The feature is set independently for each radio and is enabled by default.
Multicast Tx Rate
(Mbps)
Select the 802.11 rate at which the radio transmits multicast frames. The rate is in
Mbps. The lowest rate in the 5 GHz band is 6 Mbps.
Supported Channels
This field displays the channels that are supported for the radio mode currently
selected on the page and for the country configured on the
Global Wireless Settings
page.
Auto Eligible
Select the
Auto Eligible
option beneath each channel to include the channel in the
automatic channel assignment process.
Available MCS Indices
This field shows the Modulation and Coding Scheme (MCS) index values supported
by the radio. Each index can be enabled and disabled independently.
Rate Sets
Select the transmission rate sets you want the access point to support and the basic
rate sets you want the access point to advertise.
Rates are expressed in megabits per second.
Basic
These numbers indicate the data rates that all stations associating with the AP must
support.
Supported
These numbers indicate rates that the access point supports. You can select multiple
rates. The AP automatically chooses the most efficient rate based on factors like
error rates and distance of client stations from the AP.
Forced Roaming
Forced Roaming aims to improve users network experience by forcing a client to
disassociate with the already associated UAP, where the radio signal strength among
the client and the UAP is below the configured threshold. After being forcibly
disassociated with a UAP, the client is ideally going to associate with a nearby UAP
with stronger signal strength thus improving network experience/performance.
When is option is selected, forced roaming is enabled. The factory default is disabled
Roaming Threshold
When the signal strength diminishes below a certain threshold, the client will
disassociate with the access point and re-associate with a nearby access point that
offers a stronger signal.
The scale of the signal strength is as follows: -40dBm is considered 100%, while -
90dBm is considered 0%. The valid range is 20(%) to 50(%). The factory default is
20(%)
Multicast to Unicast
Convert all
multicast
packets into unicast packets and transmits them to each service
client in unified AP. In current unified AP firmware
implementation,
since data rate on
unicast is higher than that on multicast, doing so can increase network performance
.
The factory default is disabled
DHCP Offer/ACK to
Unicast
Convert DHCP offer/ACK broadcast packets into unicast packets in unified AP. In
current unified AP firmware
implementation,
since data rate on unicast is higher than
that on multicast, doing so can increase network performance
. The factory default is
disabled
