The Physical Layer of HomePlug AV operates in the frequency range of 2 - 28 MHz and provides a 200 Mbps PHY channel rate and a 150 Mbps information rate. Depending on the protocol version used, the maximum throughput data rate is between 70 and 80 Mbps. As UDP has less protocol overhead than TCP, UDP can result in a slightly higher data rate than TCP. In general, 200Mbps is a theoretical transfer rate. In reality, your BiPAC 2071/2072/2073/2074 transfer rate is highly related to the quality of the power line network environment, the device quality, its transfer range, and the overall effect of other devices being used.
