This is only displayed when encryption is enabled by license
key. Must contain the same value as Encryption Key.
Tx Max Power
This attribute controls the maximum transmit power (dBm)
the unit is permitted to use when installing and operating the
wireless link. The maximum setting for a particular region or
country is controlled by the License Key. It can be changed
in 1dB steps.
Why Reduce Transmit Power?
If the link losses are low
and the link data rate and availability targets are being easily
achieved, the transmitted power level may be reduced with a
consequent benefit to other users of the band, such as fixed
satellite links.
Ranging Mode
During installation, the wireless units perform “Automatic
Ranging”. The ranging mode allows the installer to control
the behavior of the system’s automatic ranging algorithms.
The default value is 0 to 40 km (0 to 25 miles). If the installer
is required to install a link of greater than 40 km (25 miles)
then the ranging mode attribute MUST be configured to ‘0 to
100km’ (0 to 62 miles) or ‘0 to 200km’ (0 to 124 miles) mode
depending on the range of the link.
NOTE
If preferred, range functions can be configured to
operate in miles, as described in
