Abstract
China mobile is using 3G and WiFi to construct a everywhere wireless network ,named wireless city.The lighting management system make every city lighting unit to access a unified management platform via the wireless network, so that realize the acquisition of working state, the setting of work mode and the automatic report of fault for every lighting unit.
