HomePlug Green Phy for IoT

HomePlug Green Phy for IoT is part of CODICOs product range.

Modules and Chips Configured for Home Control

In addition to e-mobility, there are various other applications for powerline communication in the field of IoT, such as smart metering, i.e. the remote reading of electricity meters, or home control applications. What matters here is a reliable connection. At the same time, the data should be transmitted securely and encrypted.

This means that overhead data and with it the whole amount of transmit data often is increased and the data rates of Narrow Band PLC are not enough for time critical applications with many nodes involved. On the other side Broad Band PLC with it´s very high data rates are oversized for these kind of applications and the pretty high power consumption speak against the use of Broad Band PLC as well. HomePlug Green Phy Standard offers a solution to this dilemma.

HomePlug Green Phy Dispenses the Subcarrier Modulation

HomePlug Green Phy dispenses entirely the subcarrier modulation and communication takes place in QPSK-Mode (Quadrature Phase-Shift Keying) of HomePlug AV only. By dispensing subcarrier modulation, it is not required anymore to characterize the channel. Both result in substantially reduced performance requirements for the integrated processor and with that in much reduced power dissipation.

At the same time the required memory can be reduced and as a result can be integrated into the MAC/PHY chip. Sensitivity can be lowered as well when running the chip in QPSK Modulation mode only compared with 1.024 QAM and so the analogue front end can be integrated as well. Both lead to a simplified system design and finally to a single chip solution. Because of the fact that frequency range, channel spacing as well as forward error correction method remain the same for HomePlug Green Phy equipment compared to HomePlug AV/ AV2/ IEEE 1901 all devices are fully interoperable and are able to communicate with each other.
