Smart City solutions are based on intelligent devices that use a physical interface to collect a wide range of data from their environment and transmit it to platforms where it is processed and analyzed. The prerequisite for this is a comprehensive, close-meshed and real-time capable network infrastructure. With the smart city system "PE Light S", network operators such as local authorities, municipal companies or special-purpose associations and/or service providers can drive broadband expansion quickly and cost-effectively.
Because with this completely pre-assembled system, which can be integrated into existing infrastructure elements such as light or traffic light poles, up to four IP-capable (Internet Protocol) devices such as cameras, electricity meters, sensors, displays or access points can be networked via fiber optic cable at gigabit speed and each supplied with an output power of up to 60 W. Thus, this system enables the implementation of a wide range of smart city solutions, from new Wifi services and effective traffic management to efficient CCTV applications. Well-known lamp and luminaire manufacturers have already developed their products into multifunctional systems.
And numerous smart projects that have been successfully implemented both nationally and internationally show that the smart city is not a dream of the future.
By expanding the wifi availability across the board, municipalities can meet the constantly growing demand for mobile Internet access. This allows new smart city solutions to be offered that make urban space even more attractive. These include location-based online content for retail, gastronomy and tourism or hotspots that enable citizens and visitors to surf the Internet free of charge while on the move.
Furthermore, public wifi access can be used to connect emergency call modules that are integrated into light poles, for example. The access points required for the hotspots can be connected to a high-speed fiber-optic network with the "pe-light-S" and their data can be distributed in a targeted manner. This is because the Ethernet switch of this Smart City system is compatible with the protocols of the IEEE-802.11-Familie kompatibel, die von allen WLAN-Geräten verwendet werden.
Smart City solutions enable municipalities to expand citizen services and offer new marketing channels that strengthen local commerce and generate additional revenue for the city treasury. One example is digital signage. Integrated displays turn light poles into information areas that are directly in the field of vision of passers-by. Using functional components for connectivity and fast fiber optic connections, the displays can be used to combine current information on traffic, events and weather with advertising. And in dangerous situations, they can be used to inform people in real time about the situation as well as the right behaviour.
Innovative mobility concepts are needed to manage the continuous growth of traffic and reduce the consequences for the environment. The key is IP-capable devices that are connected for example, via intelligent masts for street lighting. Smart City solutions allow to collect and transmit data by cameras or IoT (Internet of Things) sensors to be processed on a single platform. The current traffic situation can then be displayed on website, which drivers can access via smart devices and thus avoid traffic jams or plan their route optimally. Furthermore, information on traffic light phases or the next available parking space can be provided in real time so that traffic runs smoothly or unnecessary laps do not have to be made, i.e. CO2 emissions are reduced.
From both economic and ecological points of view, the static switching on and off of public lighting is no longer appropriate. Therefore today the ambient brightness is increasingly used as a basis, i.e. if the brightness falls below set threshold values, the light switches on, and if it exceeds them, it switches off. But even in this way it is not possible to react flexibly to changing requirements - and every light however efficient, wastes energy if it shines unnecessarily at 100 percent.
Smart City solutions use sensors to ensure that lights are only switched on at full power when vehicles or people enter the detected area, otherwise they are dimmed or switched off completely. This not only saves energy, but also reduces light pollution, which disturbs migratory birds or bats, for example, and is now also directly linked to insect deaths.
Power grids are becoming "smart grids" that enable efficient power generation and distribution. An important component of these grids are intelligent electricity meters, so-called smart meters. Unlike their analog predecessors, these digital devices have an IP interface through which they can send and receive data. This brings the days to an end when electricity meters were running kilowatt hour after kilowatt hour in the basement and someone would come by once a year to read the meter. Smart City solutions, which allow data to be transmitted over long distances via fiber-optic cable, enable electricity providers and network operators to keep track of consumption at all times, and customers have access to their current values on site. In order to connect smart meters to optical infrastructures, light masts can be upgraded to network nodes with the "PE Light S" Smart City system.
Video surveillance (Closed Circuit Television, CCTV) is an important element of security and thus also of smart city solutions, for example for pedestrian zones, squares and parks. It helps to deter potential criminals, to be able to react faster in case of danger and to document incidents. However, CCTV systems are not only used in public areas, but also in the business world, for example to protect factory premises.
If the surveillance cameras, which are often mounted on top of light poles, are IP-capable and connected to a network via fiber optic cable, high-resolution images can be transmitted over long distances without the risk of manipulation - unlike copper wires. The connection technology is usually mounted in a weatherproof housing that is located at the top of the mast, just like the cameras. This makes installation and maintenance very complex. The "pe-light-S" is different. Because this Smart City system is mounted directly behind the door cut-out of the mast. This saves time and money, as no aerial work platform has to be used. And compared to CCTV systems, where the cameras are connected individually via masts without power and connectivity using separate lines for power supply and data communication, the costs for cabling and the associated earthworks are also significantly reduced. Furthermore, the Smart City system also enables retrofit solutions for modernizing older copper-based CCTV systems through versions for IP-over-Coax or VDSL2.
As a result of the European limit values for nitrogen dioxide being exceeded, some cities have recently been forced to take drastic activities, e.g. diesel driving bans. With permanent monitoring of the air quality, such situations can be recognized at an early stage and defused using suitable measures. IoT air measuring devices permanently record the air pollution with pollutants (nitrogen dioxide, fine dust, ozone) in real time. Various evaluation options make the distribution and movement of pollutants in the area recognizable and show connections to weather and climatic influences. This enables intelligent action to reduce environmental impact. The pollutant information can also be integrated into a dynamic environmentally sensitive traffic management.
