IoT coupled with 5G are the key foundations onto which the smart city will be built. From transport to personalised services, a data-rich environment is taking shape
The smart city has been in development for the past decade. Smart City 1.0 consisted of sensor components including smart meters and intelligent lighting etc., offering advanced control, but little connectivity. Smart City 2.0 evolves these systems to deliver personalised services to everyone, as they move through the city space.
According to Deloitte, the Smart City 2.0 is already taking shape. A good example is Santander, Spain. The city has installed 20,000 sensors that connect to the Pulse of the City app citizens use to access information and, provide feedback to the city developers. Using the collected data, the city can adjust energy usage based on consumption. Citizens can also access real-time traffic information to more efficiently plan their journeys.
Closer to home, Hull has announced it will become the UK’s first city with an operating system. The platform developed by Connexin and Cisco, uses IoT to create what the developer’s call CityOS. “Developing Hull, as a Smart City will give us the opportunity to work with public and private sector partners to deliver real benefits to communities, businesses and visitors to Hull,” said Councillor Daren Hale, deputy leader of Hull City Council.
With Furqan Alamgir, founder and CEO of Connexin also commenting: “Our platform will enable Hull to become a ‘programmable city’ and move from outdated siloed service driven technologies to a central platform to improve service delivery, reduce costs and to make the most of new technologies such as IoT, AI and machine learning algorithms.”
Speaking to Silicon, Kevin Hasley, head of product at leading 5G/IoT analytics firm, RootMetrics said: “We’re on the cusp of a future where our communities become increasingly connected. In these connected communities, end-users will move seamlessly from one activity to another, all the while expecting strong performance, network reliability and ubiquity of coverage for all of their devices.
“From the factory floor to daily commuting to home and work alike, IoT sensors will be built on a foundation that requires a combination of increased capacity, coverage, and speed. Challenges still remain, from data and security concerns to an ability to assure that varied network technologies all work together as needed—our connected communities will depend on a fluid blend of 5G, LTE, Wi-Fi, and more.”
The smart cities that IoT will create, are more than collections of sensors. Smart cities take vast quantities of information they can collect and use this data to deliver more efficient services. IoT becomes the foundation onto which all of these services are built.
IoT also embraces a wider set of technologies, all of which are needed to deliver a smart city. Data needs to be analysed and understood. Here, AI and machine learning are being used. Edge computing is enabling transport systems and future autonomous vehicles to become a reality. And predictive analytics, which can take the masses of data generated by a smart city and see a pattern of usage amongst its citizens and, predict their behaviour – something that is critical to ensure services are available on demand.
As KPMG states: “Connectivity is the foundational lever for Internet of Things, allowing things to communicate continuously. Mobile internet has met the demands of bandwidth requirement along with speed. With the onset of 5G and various short-range wireless technologies the footprint of Internet of Things grows.”
The smart city must also operate with high levels of security. When key infrastructure services are connected together and, with more personal data about citizens being collected, security becomes a critical component of all smart cities. Standards and interoperable devices must all be developed with security in mind.
“Many of today’s connected objects do more than simply provide information at your fingertips – they make use of sensitive data, gather information and even impact the physical world, in many cases in critical ways,” comments Kevin Gillick, GlobalPlatform Executive Director.“Implementations requiring the highest levels of assurance may require security certifications in line with relevant standards, whereas others may not. It’s important to remember that the level of security of each implementation will depend on your risk analysis; there is no one size fits all. But businesses are not alone in this fight and much work has already been done to help them implement trust in a cost-effective and scalable way.”
Data and standards
To create a smart city, technologies must work seamlessly together. Here, standards and protocols are vital as Rohit Gupta, vice president and head of Manufacturing, Logistics, Energy and Utilities – Europe, Cognizant explained to Silicon: “One of the biggest challenges that IoT developers are currently facing is access to proprietary data, such as those generated by IoT devices, organisational data on businesses, or personal data on citizens. All of these offer higher value for richer, smart city services, but are not readily available or released to developers for analysis. Added to this is the quality of the data that developers do have access to, which, when retrieved via APIs from IoT infrastructures and other sources across cities, are often plagued with non-uniformity.”
This is echoed by David Fraser, Tech Specialist, Intel: “Standards such as those developed by the 3rd Generation Partnership Project (3GPP) for 5G will ensure the devices deployed in smart cities can communicate and send data back to an appropriate aggregation point. It is at this point where the data will be processed and analysed with the same or even greater reliability, we all enjoy with our smartphones today.
“Industry standards are the building blocks for interoperability and drive horizontalized eco-systems, which in turn will enable rapid innovation in a marketplace. Today we no longer ask the question, “Will this handset work on this network in that location?” – it just works. As users, our consumer expectations are constantly rising and morphing where customers’ needs are being anticipated and, therefore, better served. The ramp of smart city solutions will be accelerated or limited by the interoperability across devices and vendors. Cellular operators will play a significant role in bringing their expertise in the handset business to a largely new eco-system. Creating this environment based on standard and interoperability is fundamental to ensure the wide-spread adoption of smart cities.”
With Joe Hughes is the CEO at Manx Technology Group describing how standards are developing: “We have been in discussions with several cities and municipalities about the ISO 37122 standard entitled “Sustainable cities and communities — Indicators for smart cities”. The standard provides a range of indicators that a city can use to measure progress and improvements that can lead to sustainable smart city status. As the old saying goes, you can’t improve what you can’t measure. We find many organisations are more comfortable working within a standardised framework, that not only provides a direction of travel – but one that enables them to benchmark compare and even collaborates with other cities with similar sustainable goals.”
It’s vital, then, that standards are adhered to. However, in the rush to dominate this space, proprietary technologies protocols are leading. As smart home technologies are marketed by a range of developers and vendors with little shared communications standards; it remains to be seen whether a set of universal standards will emerge to support the smart city as it evolves.
For smart city dwellers, the information network they connect to disappears into the built environment around them. Uses of a smart city won’t be troubled with looking for a Wi-Fi hotspot as the entire city will be a gigantic hotspot that delivers fast 5G connectivity with very low latency.
Says McKinsey: “Smart cities add digital intelligence to existing urban systems, making it possible to do more with less. Connected applications put real-time, transparent information into the hands of users to help them make better choices. These tools can save lives, prevent crime, and reduce the disease burden. They can save time, reduce waste, and even help boost social connectedness. When cities function more efficiently, they also become more productive places to do business.”
The social aspect of the smart city is an interesting one, as to how people react to the services a smart city could deliver need to be understood. Speaking to Silicon, Tracey Harwood, Professor of Digital Culture at the Institute of Creative Technologies, De Montfort University said: “From my perspective, it’s not so much the technologies but the types of interconnected services they render possible, so it’s the ways they connect and configure that will be disruptive. The research I’ve done (working with the University of Otago in New Zealand) has focussed on how citizens will react to different kinds of IoT enabled services in the home, when travelling and when dealing with wellbeing and health-related services.
“One of the key challenges relates to the current piecemeal adoption of the technologies which presents many challenges to users, however, as more ‘things’ are added, and new smart services evolve, users will have to keep an eye on the increasingly complex system that is being created. Ultimately that means proxies will be required to intervene and implement controls to support and protect users.”
Harwood concluded: “Key to the growth of new services will be the ability of users to transfer their knowledge and understanding of IoT applications to new service contexts – and it will be the lack of experience, social mobility online or opportunities for exposure to new types of services that will hold things back. It, therefore, has to be a priority for smart service designers to keep users actively engaged in the development of systems which are ultimately going to be based on their own performance within the system.”
As the development of Smart City 2.0 embraces the raft of digital technologies that are now available, each space can be transformed. Using AR (Augmented Reality) to deliver unprecedented levels of information into the hands of every citizen, to mass transit systems that transform the infrastructure of a city, the ability to use advanced sensor technology is a key component of IoT when applied to city environments.
