Table 8 - 5.8GHz Aggregate Ethernet throughput rate versus maximum link loss
The full calculation is relatively complicated and thus Motorola has supplied a link estimator
that calculates the radio propagation and reliability of NLOS links using the PTP 600 Series
Bridge equipment.
A more detailed discussion on data rates can be found in Section 16.
