Satellite Density Satellite Density setting helps achieve maximum bandwidth in a
wireless network. It influences the receive sensitivity of the radio
interface and improves operation in environments with high
noise level.
Reducing the sensitivity of the device enables unwanted “noise”
to be filtered out (it disappears under the threshold).
You can configure the Satellite Density to be Disable, Large,
Medium, Small, Mini, or Micro. By default, Satellite Density is
disabled. The Medium, Small, Mini, and Micro settings are
appropriate for high noise environments; whereas, Large is
appropriate for a low noise environment. A long distance link
may have difficulty maintaining a connection with a small
density setting because the wanted signal can disappear under
the threshold. Consider both noise level and distance between
the peers in a link when configuring this setting. The threshold
should be chosen higher than the noise level, but sufficiently
below the signal level. A safe value is 10dB below the present
signal strength.
If the Signal-to-Noise Ratio (SNR) is not sufficient, you may need
to set a lower data rate or use antennas with higher gain to
increase the margin between wanted and unwanted signals. In a
point-to-multipoint configuration, the BSU should have a density
setting suitable for SU, especially the ones with the lowest signal
levels (longest links). Take care when configuring a remote
interface; check the available signal level first, using Remote Link
Test.
See Sensitivity Threshold Values for more information on
Sensitivity threshold values corresponding to various Satellite
Density values.
NOTE: When the remote interface is accidentally set to
small and communication is lost, it cannot be
reconfigured remotely and a local action is required
to bring the communication back. Therefore, the best
place to experiment with the level is at the device that
can be managed without going through the link. If
the link is lost, the setting can be adjusted to the
correct level to bring the link back.
Cell Size This parameter specifies the cell size for the TPC setting on the
wireless medium. By default, the cell size is configured to Large.
You can configure the cell size as Large, Medium or Small. The
TPC range is controlled by this parameter.
