Th
e link loss is the total attenuation of the wireless signal
between the two point-to-point units. The link loss calculation

= Antenna gain at the remote and local units
respectively (dBi). The antenna gain of the ODU (23.5
dBi) is used unless one or both of the units is a
Connectorized version.
For connectorized ODUs, the link loss calculation is modified
to allow for the increased antenna gains at each end of the
link.
