Multimedia PLC Systems

This chapter provides a description of innovative PLC multimedia communication technologies that provide acceptable levels of latency, jitter and reliability for the delivery of multimedia content via noisy and unreliable power line channels. Only the details of the Physical Layer Convergence Protocol (PLCP) that describe the MAC-PHY interface for the IEEE 1901 FFT-OFDM PLCP are explained in the chapter. Performance of the two-level framing approach, independent of the MPDU and channel access overheads, was presented. The chapter summarizes those results and then provide the results of detailed simulations based on measured PHY characteristics and known MAC parameters. It focuses on the key enhancements of HomePlug AV2, namely, MIMO, an extended frequency band, Short Delimiter, Delayed Acknowledgement, Effective Notching, and Immediate Repeating. External threat implies an attacker capable of eavesdropping on transmissions and sending frames within the network, but out of network access credentials.
