It is only by connecting the basic LED lights to the PLC or RFMesh with the power line that there are good results, made with the operation and energy efficiency that can have a great impact on saving energy and maintenance, with basic features such as remote control, dimming, and scheduling. . activities
Integrating street lighting with cellular technology can be achieved at a relatively low cost by providing advanced lighting equipment, providing intelligent systems that require faster response and greater security, and which includes color management, adaptive lighting and emergency response.
Once embedded in the cellular network, smart street lights can support several IoT applications that make them suitable for the smart city platform, opening up new opportunities for innovation. towns.
Points attached to street lights could also provide a new source of revenue for cities to expand cell phone access to include small cell networks, EV charging stations, or digital signage for advertisers.

A study conducted by Navigant Research for Echelon shows that the mid-range is the best choice to balance cost and performance, with the many advantages of using electric power PLC and radio technology. frequency RF mesh. However there are limits to network security, latency and bandwidth, so it is not suitable for most applications.
For basic lighting control, there are many “narrowband” connection options such as Sigfox and the unregistered LoRaWAN, and the recently approved NB-IoT, which will be very cheap but limited number of above requests. They can be used for many IoT monitoring applications, such as air quality, noise monitoring, traffic or pedestrian activity. Together with other sensors, they can support practical applications such as smart parking and garbage collection.
On the other hand, broadband options such as point-to-multipoint RF solutions, public 3G or 4G LTE networks, Wi-Fi, are more expensive, but costs are falling. This network provides the security, low latency and high bandwidth required for video and critical applications. Data rates can range from 50 Mbps – 100 Mbps. 5G comes with the promise of up to 1 Gbps. Other applications that require these features are HD video monitoring, traffic light control, and digital signage that provides real-time information to passengers. Wi-Fi can provide connectivity to businesses and citizens at large, growing the economy and bridging the digital divide.
So what internet technology is used? There is no easy answer to the question of what is the best network of street lights for a city. The choice will be based on current needs and available investments, medium-term priorities and long-term forecasts that shape the city’s needs. Perhaps it is a hybrid of these technologies that will evolve over time.
Smart Led Street Lighting: An Opportunity In Times Of Crisis
But technology is only a tool. Cities must understand their needs and which applications are appropriate at each stage of smart city development and adapt to each situation. Street lights are designed to do more than just illuminate urban and suburban areas. It can now be integrated into a broad management platform to collect and process data from smart city sensors related to transportation, energy and urban management, safety and security. Smart Street Lights adjust the lights according to the traffic and light conditions in the area. For example in dark times it can use sensors to detect cars/bicycles/pedestrians and adjust the light level in their journey. By strategically approaching the implementation of this technology, service providers and governments can increase the safety of urban areas and neighborhoods, improve the efficiency and quality of services, and enable sustainable energy use. Street lighting systems and sensors can also be integrated with communication technology, digital signage, CCTV, speakers and electric vehicle charging (
As smart connected cities  continue to grow and expand worldwide (along with climate and security measures), new methods of data collection, security monitoring, and use of renewable energy are increasing. The main benefit of smart street lights is to provide lighting based on city movements while having a bird’s eye view, coordinating street lights in a city or region. They provide improved lighting services based on movement and traffic, efficient use of electricity and data collection that will be used to improve the transport network and traffic safety. The use of LED bulbs with built-in sensors that allow the detection of approaching or departing vehicles and pedestrians, helps to do this.
With the world’s population increasing by 1.1% per year  and urbanization, the intelligent use of land and resources is an important area of research. Data collection through new technologies such as smart street lights are important sources of data and information for smart cities to improve asset management and efficient service.
Potential features of smart street lighting include dynamic information signage and emotional advertising to calm emotions. A dynamic information sign linked to sensor technology can be used to indicate areas of congestion, travel delays or nearby hazards (
The Global Smart Street Lighting Market
The concept of emotional marketing has been used in retail stores around the world, with specific smells, sounds and light effects to encourage customers to buy their products. The concept of health through hearing has been explored in underground stations in France and Japan. These ideas have the potential to be applied to smart street lighting to enable better demand management as well as safety management, for example playing music and switching lights to improve night life, using scents (specifically outdoor or urban) to enhance the environment, and audio visuals inform users of public transport vehicles arriving and departing.
Rules and regulations: The monitoring of smart street light rooms, as well as safety testing, should be discussed and planned by governments, to ensure that standards are met. In addition, the collection of data – how it is stored, to whom it is accessible and how it is organized for research purposes – must be decided, to ensure the safety of users and the public and the acceptance of the technology. Implementing other technologies, including EV charging and available hotspots, requires the government to consider and answer the following questions: Will the use of these features be free? If so, who will pay for the electricity and WiFi? Is there a cap when charging or using a hotspot?
Employee Skills Transfer: New smart street lighting technologies and remote asset maintenance systems require operations and maintenance personnel to be trained and follow specific tasks and processes. The government and relevant authorities should be in a position to have the right tools to monitor the expected results and remedial actions.
Risk: Smart lighting devices (LED dimming, sensors, CCTV, EV charger etc.) are often developed for use in other applications. With a large network of smart street lights, implementing, managing and maintaining these various components can be difficult.

Reduction: Planning use cases and implementing the number and locations of required equipment is critical. The collection of necessary equipment and related infrastructure for the operation should also be clearly analyzed and provided with responses to failure and incident management. A measurement and monitoring system must be implemented at each post, to ensure accurate power readings (for LEDs) and notification of technical errors. In addition, the processing and collection of CCTV images and sensor data should be adapted to the type of data and the purpose of data collection.
Risk: The safety and environmental aspects of active street lighting have been identified as important for safety-related issues. A major issue related to the use of sensors and cameras, which users may see as a privacy threat.
Mitigation: Reducing this risk requires promoting the benefits of technology, especially how it will improve safety, congestion, public transport services and the quality of urban space, as well as having proper control over your data .
Risk: Data privacy related to connected technologies such as street lights will be expected.
