Cityntel develops next generation context and situation aware street light control solution based on unique flat wireless mesh network and Mist computing technologies. In the course of a night the situation on the streets varies a lot. Peak hours need different lighting than quiet night hours when there are very few people accessing the street. Their solution makes street lights adjust their brightness according to an actual need. Street lights are gathering information regarding human presence, traffic intensity, weather conditions etc from various sensors deployed in the area and adjust their brightness based on this data. By using wireless mesh network sensors are able to communicate with street lights on local level.
