What is HomePlug?

This page covers basic features of HomePlug technology.It covers HomePlug AV and HomePlug GP(Green PHY) versions used in IoT(Internet of Things).

HomePlug technology is widely used for networking over existing electrical wiring in the home. This powerline communication standard is developed and managed by HomePlug Powerline Alliance.

Following standards have been evolved in HomePlug technology.
• HomePlug 1.0
• HomePlug AV
• HomePlug AV2
• HomPlug Green PHY
• HomePlug Access Broadband Power Line

The first version HomePlug 1.0 supports datarate of 14 Mbps. HomePlug AV supports a peak physical layer(PHY) data rate of 200 Mbps. HomePlug GP(Green PHY) supports a peak physical layer(PHY) data rate of 10 Mbps. Following section describes difference between HomePlug AV and HomePlug GP versions.

HomePlug AV

• Frequency Spectrum: 2 to 30 MHz
• PHY Modulation: OFDM
• No. of subcarriers: 1155
• Subcarrier spacing: 24.414KHz
• Modulation types: BPSK, QPSK, 16QAM, 64QAM, 256QAM, 1024QAM
• FEC techniques: Turbo code Rate 1/2 OR Rate 16/21 (punctured)
• Data rates: 4 Mbps to 10Mbps(ROBO), 20Mbps to 200Mbps(Adaptive Bit Loading)
• Channel Access: CSMA/CA with optional TDMA
• Channel Estimation: Adaptive bit loading per subcarier via pre negotiated tone maps

HomePlug GP(Green PHY)

• Frequency Spectrum: 2 to 30 MHz
• PHY Modulation: OFDM
• No. of subcarriers: 1155
• Subcarrier spacing: 24.414KHz
• Modulation types: QPSK only
• FEC techniques: Turbo code Rate 1/2 Only
• Data rates: 4 Mbps, 5Mbps, 10Mbps(ROBO)
• Channel Access:CSMA/CA Only
• Channel Estimation: ROBO eliminates need for pre-negotiated tone maps.
• Bandwidth Sharing: ROBO eliminates need for pre-negotiated tone maps.
• CCo capable: Yes, limited modes
