A wireless system includes a master communication device in communication with multiple slave communication devices. During operation, the master communication device establishes first wireless connectivity with each of the multiple slave communication devices via a first wireless communication protocol. Each of the slave communication devices monitors vehicular traffic at a street intersection. The master communication device receives input of monitored vehicular traffic from the multiple slave communication devices. The master communication device communicates a status of the vehicular traffic over second wireless connectivity to a wireless base station in communication with a controller. The controller generates and communicates control information based on the detected vehicular traffic to the master communication device that distribute the control information to the slave communication devices. Each of the slave communication devices controls a respective traffic light based on the control information generated by the controller.
