AN60685 - Interfacing the Cypress Powerline Communication Solution to CyFi™ Low-Power RF Module
AN60685 describes a firmware project that bridges powerline communication (PLC) across different electrical phases using an Artaflex AWP24S CyFi™ radio frequency (RF) module. This wireless phase-coupler application works with the Cypress PLC solution’s network protocol. The project for the CY8CPLC20 is attached.
In most buildings, electrical power is divided into phases. For example, in many homes in the U.S., about half of the 110-V lights, appliances, and outlets use one phase and the rest use the other phase. Every home has a small level of coupling between the two phases at the transformer that supplies power to the house. This coupling is inductive; the higher the frequency, the more it attenuates the signal.
