Dynamic Data Rate
Selection
Enabled PTMP/WiMAX Allows subscribers to receive the maximum data rate possible.
Subscriber Station
Class
G711 VoIP UGS WiMAX
Subscriber
Stations
Defines the subscriber station class for the AP. Subscriber station classes are defined on
the Groups > WiMAX page.
Uplink Modulation bpsk-1-2 WiMAX
Subscriber
Stations
Drop-down menu that defines the uplink modulation type for the subscriber station.
Downlink
Modulation
bpsk-1-2 WiMAX
Subscriber
Stations
Drop-down menu that defines the downlink modulation type for the subscriber station.
VLAN Mode Inherit WiMAX
Subscriber
Stations
Drop-down menu that defines the VLAN mode of the AP. Inherit - The AP will inherit the
VLAN settings from the subscriber class. Transparent - Tagged and untagged traffic is
passed along unless blocked by a PIR restriction.
Receive Antenna Diversity Cisco Drop-down menu for the receive antenna provides three options:
Diversity —Device will use the antenna that receives the best signal. If the device has
two fixed (non-removable) antennas, the Diversity setting should be used for both receive
and transmit antennas.
Right —If your device has removable antennas and you install a high-gain antenna on the
device's right connector (the connector on the right side when viewing the back panel of
the device), use this setting for both receive and transmit.
Left —If your device has removable antennas and you install a high-gain antenna on the
device's left connector, use this setting for both receive and transmit.
Transmit Antenna Diversity Cisco See description in Receive Antenna above.
Antenna Diversity Primary Only Intel 2011,
Symbol 4131
Drop-down menu provides the following options:
Full Diversity—The AP receives information on the antenna with the best signal strength
and quality. The AP transmits on the antenna from which it last received information.
Primary Only—The AP transmits and receives on the primary antenna only. Secondary
Only: The AP transmits and receives on the secondary antenna only.
Rx Diversity—The AP receives information on the antenna with the best signal strength
and quality. The AP transmits information on the primary antenna only.
Transmit Power
Reduction
0 Proxim Transmit Power Reduction determines the APs transmit power. The max transmit power is
reduced by the number of decibels specified.
Channel 6 All Represents the AP's current RF channel setting. The number relates to the center
frequency output by the AP's RF synthesizer.
Contiguous APs should be set to different channels to minimize "crosstalk," which occurs
when the signals from APs overlap and interfere with each other. This RF interference
negatively influences WLAN performance.
802.11b's 2.4-GHz range has a total bandwidth of 80-MHz, separated into 11 center
channels. Of these channels, only 3 are non-overlapping (1, 6, and 11). In the United
States, most organizations use only these non-overlapping channels.
Neighboring APs Blank All Represents top five contiguous access points calculated by summing the number of
roams to and from the access point and the access point of focus. Contiguous APs should
be set to different channels to minimize "crosstalk," which occurs when the signals from
APs overlap and interfere with each other. This RF interference negatively influences
WLAN performance.
