Lighting of represents between 40% and 70% of the electricity bill of councils. Many cities are already upgrading their lighting infrastructure with highly energy-efficient light-emitting diodes (LEDs) along with IoT device integration, enabling effective remote management of public lighting.

Smart connected lighting provides on average more lighting hours, but with dimmed power, optimally adjusting to the local need and the preferences of citizens. From a technological point of view, the digitalisation of lighting is based on three pillars:

1. Sensors and actuators.
2. Connectivity.
3. Data processing.

Telefónica’s Smart Lighting solution improves energy efficiency and generates savings as it allows lights to be fully controlled. It provides greater efficiency and control, and improved city quality through the adaptation of facilities and the use that is made of them. In addition, these solutions reduce CO2 levels by reducing light pollution, energy consumption, and acting against possible unjustified deviations.

This system allows lighting systems to be controlled and monitored; lights can be turned on and off remotely, and light levels controlled. This not only improves energy efficiency; it also optimises maintenance task and facilities management, monitoring consumption and dealing with possible unjustified irregularities.

The communication technology used is NB-IoT due to the small size of the data packets sent, the high concentration of nodes installed in cities and the systems’ low energy consumption.
