Aggregate Ethernet throughput rate v maximum link loss

The equipment capability is given in Table 6 and Table 7. These tables give the Ethernet
throughput rate versus link loss for PTP 600 Series Bridge in all modes. Adaptive modulation
will ensure that the highest throughput that can be achieved instantaneously will be obtained
taking account of propagation and interference. The calculation of Equation 1 needs to be
performed to judge whether a particular link can be installed. 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.
