The communication focus for the Internet of Things (IoT) has been mainly wireless with battery-powered devices. For fixed installations where power consumption is much higher than a battery would provide during a 10 year period, wired power with wired communication would be needed. Example systems are heating, ventilation, and air conditioning. Using wired communication would leave wireless space free for non-stationary communication.

On the physical communication layer, the world has many wired protocols, like RS485, M-Bus, and so on. We believe that for IoT the power demand for the communication must be even lower than the existing protocols provided. Today's methods require careful wiring because the signal reflections on the bus will make the data reception fail.
