Attribute
Meaning
Antenna Gain
This value represents the amount of gain introduced by an external
antenna (minus cable loss). This value is used in calculating the unit’s
Equivalent Isotropic Radiated Power (EIRP) level. For certain Country Code
configurations, the unit’s EIRP may be limited based on regional
regulations.
Subscriber Module
Target Receive
Level
Each SM’s transmitter output power is automatically set by the AP. The AP
monitors the received power from each SM and adjusts each SM’s
transmitter output power so that the received power at the AP from the SM
is not greater than what is configured in SM Target Received Power Level.
These automatic power adjustments ensure that the SM is not transmitting
excessive energy (raising system noise level) and that the SM is able to
achieve an optimal modulation state (and maximum achievable
throughput).
Nominally, target receive levels must be set lesser than -60 dBm in order to
prevent interference from co-located co-channel sectors.
Uplink Antenna
Selection
Uplink Antenna Selection specifies the antenna to be used in the uplink.
This parameter is specific to ePMP 2000 APs with optional Smart Antenna.
Auto: The AP decides which antenna to use (sector or Smart Antenna) for
uplink communications based on internal quality metrics.
Forced Sector Antenna: The AP uses the Sector Antenna for all SM uplink
communications.
Forced Smart Antenna: The AP uses the smart antenna for all SM uplink
communications.
Note
If the AP is configured with Uplink Antenna Selection set to Auto and an
SM is set to Forced Sector Antenna or Forced Smart Antenna, the SM
setting will be enforced.
If the AP is configured with Uplink Antenna Selection set to Forced
Sector Antenna or Forced Smart Antenna and a SM is set to a conflicting
Forced
setting, the AP’s setting will be enforced.
Scheduler
Downlink/Uplink
Ratio
Configure the schedule of downlink traffic to uplink traffic on the radio link.
The first three options, 75/25, 50/50 and 30/70, allow the radio to operate in
a fixed ratio on every frame. In other words, this ratio represents the
amount of the total radio link’s aggregate throughput that will be used for
downlink resources, and the amount of the total radio link’s aggregate
throughput that will be used for uplink resources. The fourth option,
Flexible, allows the radio to dynamically choose the amount of the total
radio’s aggregate throughput that is used for downlink and uplink
resources, every frame.
