A smart street lighting system and method employs a plurality of street lights having a luminaire, a luminaire associate and a support pole. A communications module is contained within the luminaire associates and a power line is contained within the support poles. The power line is coupled to the communications module, the luminaire associate and the luminaire, and a steerable millimeter wave radar operatively coupled to the communications module. The communications module operates in a radio frequency network in a frequency range of 57-64 GHz. The steerable millimeter wave radar provides a signal reflected from a target that may be received by one of the luminaire associates within the system. A powerline communications system interfaces with the radio frequency network to provide communications between the communications modules in the street lights and the PLC system.

A computer implemented method and system for determining reliability of a machine includes receiving one of a machine data from one or more locations through an internet of things (IOT) based machine wearable sensor network. The method further includes storing the data in a distributed computer database communicatively coupled to an enterprise resource planning (ERP) system and extracting, through a computer server, one or more entity information from the data to compare against a pre-defined baseline. Further, mapping, though a big data machine learning engine, the extracted one or more entity information into a multi-classification model. The method includes indicating, through a machine learning engine coupled to a predictive analytics engine, on a user interface a set of analytical predictions for machine maintenance, repair and operation.
