An LED light and communication system is in communication with a broadband over power line communications system. The process is based on precipitating a peroxide compound from an acidic peroxide solution of zirconium and provides a simple, economical method for producing the zirconium peroxosulfate powder and its derivatives with degree of zirconium recovery more than 99%. If more than a threshold number of pings are missed from a node, the system performs fault detection by entering a freeze state in which nodes do not send or receive any messages except ping messages.
