An Overview of the HomePlug AV2 Technology

Abstract

HomePlug AV2 is the solution identified by the HomePlug Alliance to achieve the improved data rate performance required by the new generation of multimedia applications without the need to install extra wires. Developed by industry-leading participants in the HomePlug AV Technical Working Group, the HomePlug AV2 technology provides Gigabit-class connection speeds over the existing AC wires within home. It is designed to meet the market demands for the full set of future in-home networking connectivity. Moreover, HomePlug AV2 guarantees backward interoperability with other HomePlug systems. In this paper, the HomePlug AV2 system architecture is introduced and the technical details of the key features at both the PHY and MAC layers are described. The HomePlug AV2 performance is assessed, through simulations reproducing real home scenarios.

Improving Capacity of Smart Grid Wireless Backhauls with Deadline Ordered Scheduler and Packet Concatenation

“…As for NAN, we choose PLC as the lower-layer communication technology and adopt HomePlug AV2 [10] standard. Finally, as for the communication technology of WAN, we focus on LTE since it is the most popular wireless WAN technology today, and we will employ packet concatenation with LTE at the concentrators.…”

“…5) and encapsulates them with a header, optional Arrival Time Stamp (ATS), and a checksum to create a stream of MAC frames. The stream is then divided into 512 octet segments, encrypted and encapsulated into serialized PHY Blocks, and packed as MAC Protocol Data Units (MPDUs) to the PHY unit which then generates the final PHY Protocol Data Unit (PPDU) to be transmitted onto the power line [10], [12].

Power Line Communications: Understanding the Channel for Physical Layer Evolution Based on Filter Bank Modulation

“…The first version HP 1.0 was capable to deliver up to 14 Mbps, the second version HPAV reached a peak rate of 200 Mbps, and the latest version HPAV2 [2], completed in 2012, promises 2 Gbps of peak rate thanks to the extended bandwidth up to 86 MHz, multiple wire transmission (MIMO), precoding and adaptation together with a number of advanced techniques at the MAC layer. However, the first world wide broad band (BB) standard was IEEE P1901 which was ratified in 2010 [3], followed by ITU G.9960 (known as G.hn) [4].…”

“…As can be noted, η decreases as the bandwidth increases. This is due to a lower transmission PSD limit in the band beyond 30 MHz (−80 rather than −50 dBm/Hz, as done for instance in the HPAV2 standard [2]) and to a larger channel attenuation which increases with frequency.…”

BIT loading in MIMO-PLC systems with the presence of interference

“…The HomePlug AV2 specification recommends the MIMO technology to achieve higher data rates as well as a larger coverage [1,2]. MIMO-PLC is feasible since a protective earth (PE) wire is available in addition to phase (P) and neutral (N) wires.…”
