Lighting the way to tomorrow

The world’s largest Internet of Things project for street lighting so far can be found in San Diego. By the end of last autumn, 3,200 sensors in the city’s street lights (which have been replaced with energy-efficient models) had been connected to the LTE network. Improvements can thus be made to the city’s traffic and parking management, while the roads and streets have thus been made safer and the air quality monitored at the same time. The sensors, which transmit data in real time, can also be used to alert drivers to free parking spaces and to assist the emergency services. The costs for the project come to almost USD 30 mln, but the city authorities are not ruling out expanding it by installing another 3,000 sensors.Kalisz is one of the Polish cities that has decided to upgrade its lighting system Several benefits at once Cities in Poland are also increasingly opting to replace traditional street lighting with energy-efficient alternatives.
