Summary
The following summarizes these guidelines. We have seen installations that
greatly deviate from these guidelines yet still work very well. Each installation is
different and will need to be optimized based on the conditions present in the
field and the goals of the user.
Frequency Division Duplexing (FDD) is best for:
•
Maximum possible throughput
•
Minimum possible latency
•
Installations that are free of reflective and scattering elements
•
Areas that see lower amounts of rainfall
•
Scenarios with more available spectrum
Time Division Duplexing (TDD) is best for:
•
Co-location with other master nodes
•
Robustness in areas that see the most rainfall
•
Scenarios with less available spectrum
•
Less than ideal installations, such as installations near obstructions or
scattering elements
These guidelines are only general recommendations. For example, we have
successfully co-located FDD links and installed FDD links that work on a single
frequency at short range.
