Appendix B
This appendix has information on MoCA signal attenuation characteristics and link
quality.
MoCA PHY Rate vs. Receiver Sensitivity
The MoCA transmitter adjusts its bit rate automatically, depending on channel
quality, to maintain a low bit error rate (BER) at the MoCA receiver. For that reason,
the PHY rate is a measure of link quality. PHY rate vs. receive level is plotted in the
diagram below.
Cable Loss at 1150 MHz.
