Chapter 3: System planning Link planning
LINKPlanner for synchronized networks
TDD synchronization should be planned using LINKPlanner. This will provide the necessary
TDD frame parameter values which are required to complete a synchronized installation.
Please refer to the LINKPlanner User Guide.
Path loss
Path loss is the amount of attenuation the radio signal undergoes between the two ends of the
link. The path loss is the sum of the attenuation of the path if there were no obstacles in the
way (Free Space Path Loss), the attenuation caused by obstacles (Excess Path Loss) and a
margin to allow for possible fading of the radio signal (Fade Margin). The following calculation
needs to be performed to judge whether a particular link can be installed:

Adaptive modulation
Adaptive modulation ensures that the highest throughput that can be achieved instantaneously
will be obtained, taking account of propagation and interference. When the link has been
installed, web pages provide information about the link loss currently measured by the
equipment, both instantaneously and averaged. The averaged value will require maximum
seasonal fading to be added, and then the radio reliability of the link can be computed. For
minimum error rates on TDM links, the maximum modulation mode should be limited to
64QAM 0.75.
For details of the system threshold, output power and link loss for each frequency band in all
modulation modes for all available channel bandwidths, refer to System threshold, output
power and link loss on page 3-60.
