Device Type Description
PTMP/WiMAX Allows subscribers to receive the maximum data rate possible.
Defines the subscriber station class for the AP. Subscriber station classes are defined on
Subscriber the Groups > WiMAX page.
Stations
WiMAX Drop-down menu that defines the uplink modulation type for the subscriber station.
Subscriber
Stations
WiMAX Drop-down menu that defines the downlink modulation type for the subscriber station.
Subscriber
Stations
WiMAX Drop-down menu that defines the VLAN mode of the AP. Inherit - The AP will inherit the
Subscriber VLAN settings from the subscriber class. Transparent - Tagged and untagged traffic is
Stations passed along unless blocked by a PIR restriction.
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.
Cisco See description in Receive Antenna above.
Intel 2011, Drop-down menu provides the following options:
Symbol 4131
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.
Proxim Transmit Power Reduction determines the APs transmit power. The max transmit power is
reduced by the number of decibels specified.
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.
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.
