An embodiment is a method including receiving, by a first device via a mesh communication network, a first broadcast message over a first communication channel, the first broadcast message having a first hop count, receiving, by the first device via the mesh communication network, a second broadcast message over the first communication channel, and determining, by the first device, whether the second broadcast message is a consistent broadcast message as the first broadcast message, the determining including determining, by the first device, whether the first broadcast message has a same originator address as the second broadcast message, and determining, by the first device, whether the second hop count is larger than the first hop count.

Apparatus and methods for mesh communication networks with broadcast messages

The method transmits a long packet of digital data over a poly-phase power line affected by impulsive noise synchronous with phase voltages. Instead of using very complicated coding schemes, starting from the knowledge of the typical power line scenario, useful information is transmitted where noise synchronous with the main signal is absent. Time-intervals of a known or estimated duration during which the poly-phase power line is affected by impulsive noise are determined, and dummy data during the time-intervals, and useful data during other time-intervals free from impulsive noise, are transmitted.

An electronic synchronous/asynchronous transceiver device for power line communication networks is integrated into a single chip and operates from a single supply voltage. The transceiver device includes: at least an internal register that is programmable through a synchronous serial interface; at least a line driver for a two-way network communication over power lines implemented by a single ended power amplifier with direct accessible input and output lines that is part of a tunable active filter for the transmission path; and at least a couple of linear regulators for powering with different voltage levels different kind of external controllers linked to the transceiver device.
