While network security has always been important as a means to protect the physical infrastructure, and the data and content flowing though the network, it is gaining increased attention in the course of 5G and beyond 5G networks, because networks become deeply rooted in our society in the business, governmental and private spaces.
Continue readingICT for smart sustainable cities in Europe – An overview
Today, 75% of European citizens live in cities. This percentage is expected to grow to 80% by 2050. Cities consume about two thirds of the world’s energy and are responsible for more than 70% of global man-made CO2 emissions. Thus, cities play a crucial role for reaching the European Union’s CO2 reduction goals and the UN sustainability goals. Information and communication technologies are of key importance for enabling cities to become sustainable. The concept for ICT-enabled sustainability on municipal level is called “smart sustainable cities”.

Today’s urban sprawl can easily be summed up by one figure – 75% – which corresponds to the EU’s urban population. It is easy to imagine the resulting high level of resources used and the devastating effects on the environment. The solution? Transforming our cities into smart and sustainable innovation hubs by using the latest findings in the fields of energy, transport and information and communication technology (ICT). This is what STARDUST is all about.

One of the major initiatives promoting the development of smart sustainable cities in Europe is the Covenant of Mayors for Climate & Energy. It was launched in 2008 with the ambition to gather local governments voluntarily committed to achieving and exceeding the EU climate and energy targets. Currently the Covenant of Mayors comprises more than 10,200 municipalities worldwide with a total population of 322 million inhabitants. Eurescom message editor-in-chief Milon Gupta interviewed Heidelberg’s mayor Prof. Dr. Eckart Würzner about the progress towards sustainable development in his own city and the cities of Europe. Prof. Dr. Würzner has contributed to this progress not only as mayor, but also as political board member of the Covenant of Mayors for Climate & Energy and president of the climate protection network Energy Cities.
What is your city’s most important sustainable development goal for the next 10 years?
E. Würzner: Heidelberg has been committed to sustainable development since the 1990s as a direct result of the Aalborg Charter [Charter of European Sustainable Cities and Towns Towards Sustainability, 1994 – the editor]. Since then, the urban sustainable development plan has been continuously updated. The newest update is currently running, which is for the first time based on the SDGs [17 Sustainable Development Goals of the United Nations – the editor]. One of the most important goals is SDG 13 – Climate Action.
Our climate protection concept passed the city council 25 years ago and has been constantly renewed. In 2019 Heidelberg declared the climate emergency. This created new measures and accelerated the implementation of local climate protection measures for achieving Heidelberg’s goal of climate neutrality by 2050.
Which activities have you planned and launched to achieve your city’s sustainable development goals?
E. Würzner: Climate protection in Heidelberg extends into numerous administrative areas and also into further important SDGs, including SDG 7 [Affordable and Clean Energy], SDG 9 [Industry, Innovation and Infrastructure], and SDG 11 [Sustainable Cities and Communities]. In addition to the energy transition, there is also a need for a traffic transition towards environmentally compatible transport and energy-efficient technologies.
In Heidelberg the greatest savings in CO2 emissions can be achieved in the area of building renovations, renewable energies, energy efficient buildings and the transport sector. That is why our focus is on sustainable renovation and sustainable mobility. Therefore the municipality cooperates in various fields of action with local stakeholders like the university, the municipal utility, and the enterprises.
What is the role of ICT for achieving your city’s sustainable development goals?
E. Würzner: Heidelberg is very active in the field of digitisation. The city continues to make steady progress towards becoming a smart city. From broadband expansion and public WiFi to online public participation and open data, digitised infrastructure is set to become as much a part of essential local authority services like electricity, gas and water. The objective is to use new technologies to sustainably improve the lives of all our citizens.
We implement intelligent solutions for different areas of urban development with the help of innovative technologies. In the area of climate protection, for example, these are intelligent house controls to increase resource efficiency. In the case of municipal buildings, energy consumption has been reduced by 50{b28ae05319d94bff0b4d65c5a9f4524dd588360f05c61ef440e1608e0a1c4144}.
How are Energy Cities and the Covenant of Mayors for Climate & Energy contributing to achieving the vision of smart sustainable cities in Europe?
E. Würzner: The political goals of the networks are to empower the cities in their actions and to strengthen collaboration between them. It is important to give the cities a louder voice at the international level. Therefore, we must link the political commitment of the cities to advocacy on European level. The networks should act like a lobby for financial resources, programmes and European laws for climate protection at city level. The cities put policies and institutional settings, frameworks of climate and energy goals into concrete practice. It is not enough for mayors to be experts at negotiations or conferences. It is most important to give them the right to be a part of the decision-making process. Energy Cities and the Covenant of Mayors can provide the framework for this work. Climate issues must become the guiding principle of EU politics, not only in position papers. The European Green Deal is a first and important step. In cooperation with other networks, Energy Cities should ensure that the Green Deal becomes a reality.
Which major societal, economic and technological challenges need to be tackled in the coming years on the way to smart sustainable cities in Europe?
E. Würzner: The question is if smart cities will be low-energy cities with energy-saving and climate-protection objectives. We have to offer solutions for the contradiction between promoting energy-saving objectives and increasing the number of electronic devices exponentially. More importantly, digital technology may one day be able to optimise the urban system. We need a complete change of paradigm.
Inventing short-distance cities, reclaiming urban space monopolised by cars and returning it to pedestrians and cyclists as well as relocating a significant share of the production – including food production – to the city are just a few examples of urban policies that are more important for smart cities than just achieving the energy transition.
Ultimately, smart sustainable cities are first and foremost cities designed for enabling their inhabitants to lead a free, low-energy life, without being trapped in a technical system.
Co-creation of smart sustainable cities
The 5G SOLUTIONS project

In 2050, two thirds of the world’s population will live in cities, according to the United Nations [1]. In order for cities to handle this growth in a sustainable way, they have to become energy efficient and climate resilient, improve mobility and healthcare, as well as become inclusive and attractive for all citizens. ICT solutions and especially 5G, the next generation communication technology, can become an important enabler for solving these challenges.
5G SOLUTION is one of eight projects under Phase 3 of the 5G-PPP, a private-public partnership initiated and funded through The European Commission Horizon 2020 programme, with the aim of supporting research and innovation within the smart city vertical along with other adjacent verticals [2]. This is a consortium of 26 European partners from academia, research centers, telecom operators, large industries and SMEs in 5G SOLUTIONS [3]. Telenor is a 5G experimental facility provider in the project leveraging the 5G-VINNI platform [4]. While the Norwegian University of Science and Technology (NTNU), Department of Mechanical and Industrial Engineering is a partner in the project addressing “Factories of the Future”, the NTNU smart sustainable cities is a cross-department and cross-disciplinary knowledge cluster and an external partner collaborating with Telenor to address “Co-creation for smart sustainable cities”.
Smart city use cases
In 5G SOLUTIONS an array of smart city use case scenarios are outlined and specified for upcoming trials and validations both technologically and business wise.
The smart city use cases outlined in 5G SOLUTIONS include:
- Smart street lighting: Electricity consumption is estimated to increase up to 80{b28ae05319d94bff0b4d65c5a9f4524dd588360f05c61ef440e1608e0a1c4144} in cities until 2030 compared to 2005 [5]. Reducing the electricity for lighting up streets and public areas is one area to become more energy efficient. Dimming or even switching on and off street lamps in low-traffic areas can be activated through sensor- or camera-monitoring persons or vehicles passing by. This will help the municipalities saving money and becoming more eco-friendly, while avoiding negative effects such as car accidents.
- Smart parking: Thirty percent of traffic in cities are looking for a parking space [6]. Smart parking solutions using 4K video cameras for real-time detection of occupancy and frequency/turnover of use of metropolitan area parking spaces will contribute to reduction of congestion and emissions, improve traffic safety, and simultaneously allow higher quality of life for the residents. This solution can also be combined with optimizing charging and electric network usage of electric cars and other electric vehicles such as buses or bikes.
- Smart buildings and campus: Internet of Things sensors can be deployed in private office buildings and public facilities to measure air quality, room occupancy, etc., reduce the energy consumption, allow for predictive maintenance, and utilize proximity lighting turning off heating or air conditioning when no one is present. 4K video cameras monitoring and automated detection of dangerous situations can help improve the physical security of the campus as well as the safety of its occupants. Understanding how buildings are used through sensors can also help with better planning of spaces and energy reduction for buildings.
- Smart harbour and ports: The Yara Birkeland fertilizer plant at port Herøya in Norway aims to have the world’s first fully electric autonomous container ship with zero emissions, replacing 40.000 diesel powered truck haulage journeys a year. 5G infrastructure will be deployed on the port premises supporting self-driving vehicles in addition to digitalizing working processes, e.g. remote VR/AR enhanced maintenance and operation, also providing a safer working environment.

Social innovation
In addition to these four vertical use cases, a new cross-cutting case for smart cities co-creation will be designed around social innovation. This will entail, amongst others, virtual and distributed co-creation between citizens and professional stakeholders and decision makers, supported by reliable live visual distribution and interactive communication with multiple remote areas, the use of digital twins, the exploration of sensor deployment, support for citizen science, and mixed reality media.
All the use case scenarios can be realized through support from 5G technology with higher data rate and lower latency, as well as massive machine-type communication such as connecting high numbers of sensors and IoT devices. A precondition is that the smart city ecosystems of partners and stakeholders are present, starting with municipalities and local governments enabling collaboration with potential industry and academic partners across several sectors [7].
Business model enablement and outlook
Information from these scenarios on energy consumption and behavioural patterns, whether it is data generated by citizens, IoT sensor networks or city level data that has broad communal use and is privacy-protected, could be made available across vertical silos proposing new collaborative frameworks and business models rewarding openness, transaction and data sharing. This can enable start-ups, SMEs, NGOs and local communities to take advantage of this data and build new apps and services relevant to the wider community. Applying machine learning or artificial intelligence techniques and algorithms on these data sets can also be an important enabler for detecting cost-efficient and environmentally friendly solutions beneficial for the ecosystem players and in the end for the citizens’ well-being.

The new 5G network system promises numerous advantages for a large number of vertical sector applications. Horizon 2020 project SliceNet has designed, implemented and executed a smart city pilot to showcase the advantages of network slicing, a new concept that has been introduced in the 5G system. Network slicing enables the operation of independent logical networks over the same physical network infrastructure.
Smart city applications include, among others, metering solutions for gas energy and water consumption, remote monitoring of city infrastructure like pollution, temperature, humidity and noise, real-time traffic information and control, city or building lights management and public safety alerts for improved emergency response times. The smart city pilot in SliceNet has defined a 5G network slicing architecture for the vertical’s smart lighting application as a solution for one of the many smart city applications.
Architecture of the pilot
The smart lighting pilot is based on an end-to-end sliced 5G architecture, vertical-oriented, technically supported through innovative network resources management, control and orchestration, enabled to support the service requirements by providing Quality of Service (QoS) and Quality of Experience (QoE) service assurance through cognitive machine learning algorithms.
The pilot provides the transition from existing concepts of Internet of Things (IoT) implementations, such as those based on the low-power wide-area network protocol LoRa (Long Range) to standards based LTE-M/Nb-IoT and further to the new 5G network system for smart city use cases.
The pilot system is based on different ICT components and capabilities such as IoT applications and services, virtualised network infrastructure, virtualised network functions implementation, dynamic resources, slices and services orchestration, concurrent slices resources allocation, cognitive modules for QoS/QoE assurance and interfaces facilitating the interaction with the vertical application.
Using existing 4G network components, the pilot provides the possibility to instantiate end-to-end slices stretching from the users’ equipment, i.e. lighting poles, up to the IoT application running in a data centre, including all necessary network components that support the use case.
The key achievements, performance and business indicators (KPIs) are demonstrated in a real environment, integrating the technologies and demonstrating the capabilities and key innovative aspects of the project implementation, with a focus towards commercialization. The key aspects addressed by the smart lighting pilot are:
- Adopted model of 5G stakeholder roles and responsibilities, with the vertical stakeholder in the loop
- Time-to-market for business solution delivery
- Customer friendly usage
- Innovative programmable infrastructure deployment, resource, slice and services monitoring and exposure of collected data to the vertical application
- Service QoS/QoE KPIs assurance, metrics (bandwidth, delay, jitter, packet loss)
- Service provision in a massive Machine Type Communication (mMTC) slice
- New operational model for deployment, operation and system service assurance
Deployment and measurements
The smart lighting pilot has been deployed and demonstrated in a real live scenario in Bucharest, Romania. A series of measurements have been conducted to obtain results about the potential capabilities of the system. The measured end-to-end latency is in the range of 27ms on average and well below the target key performance indicator for this application. The measured packet loss observed was 0{b28ae05319d94bff0b4d65c5a9f4524dd588360f05c61ef440e1608e0a1c4144}. Longer-term measurements under a larger variety of configurations have to be conducted, in order to add more realism to the estimation of service reliability.
Impacts
The pilot has important societal and business impacts. The system integration and use case piloting in a real environment provided a basis for wide communication of the potential through Orange’s Romania ties into industry, academic institutes, media and last but not least the city hall. The Orange Fab programme provides the co-innovation environment to channel the results to start-ups and other partners.
Commercialisation opportunities emerge for the whole service, i.e. the smart lighting application or parts thereof such as the programmable infrastructure the service is based upon, the vertical application orchestrator, or the vertical API.
A video summarises the smart lighting application (https://youtu.be/zmxJbxpSTYQ).
Collaboration in the 5G PPP
The pilot provided a unique 5G PPP collaboration opportunity between the projects SliceNet and Matilda. Together the two projects provided a holistic, innovative framework for the design, development, life-cycle-management and orchestration of 5G-ready applications and the related network services. The whole system is based on a programmable infrastructure, virtual network functions and network services, the 5G-ready applications and application components all available through a 5G marketplace. The collaboration showcased how this innovative smart lighting application is deployed from the 5G marketplace into the infrastructure.
Standardisation
It has been clear from the start that the solution must be standards based. Where standards do not exist or are not mature enough yet, the project actively engaged with the relevant bodies and contributed in shaping standards as follows:
- ETSI Work Item for “PoC proposal for Predictive Fault management of E2E Multi-domain Network Slices” (using a smart grid use case as an example);
- ITU-T Work Item for “Vertical-assisted Network Slicing Based on a Cognitive Framework” (using an eHealth use case as an example);
- ITU-T Work Item for “Anomaly prediction and integration for eHealth use case based on vertical feedback” (using an eHealth use case as an example);
- ITU-T Work Item for “Noisy neighbour detection and integration in a virtualized infrastructure” (using a smart city use case as an example);
- ITU-T Work Item for “Machine learning based end-to-end network orchestration and network slice management” (across use cases).
Outlook
Smart cities will make significant use of 5G capabilities to improve their services for citizens. SliceNet piloted and validated business opportunities relying on 5G features like network slicing, flexible network management and provision of mMTC and enhanced Mobile Broadband (eMBB) services at scale. It implemented a closed-loop cognition-based autonomous network slice control, management and orchestration framework.

Systems beyond 5G are set to shift the network communication paradigm, which will heavily affect the information and communication sector. 5G is expected to deliver increased connectivity, highly fault-tolerant communication, and maximum spectral efficiency while keeping latencies at negligible limits. The aspiration is to transform the current 5G wireless thinking from focusing on “local” improvements (e.g. isolating the radio access level or the resource management level) to realizing a vision of pervasive mobile virtual services through network-managing computing and connectivity functions in an integrated way. This beyond 5G transformation envisions bringing together novel radio architectures and an Artificial Intelligence (AI) network approach across various tiers of the technology stack and deployment scenarios.
