What is a smart city? 

A Smart City uses digital technology to collect and provide feedback to its citizens, visitors and government.. This is accomplished by use of IoT sensors and various technologies to connect different components together. 

The overarching mission of a smart city is to optimize city functions, drive economic growth, all while improving quality of life using smart technology and data analysis. After the data is collected and analyzed, the real value is taken in the form of action. What will the city do now that they have this information?Having the ability to collect real time feedback from its sensors, citizens and visitor engagement provides the city a way to make level informed decisions concerning rural and urban planning, transit and traffic control, waste collection, recycling, and so much more. 

Factors that put the ‘smart’ in smart city

There are a few factors that are the basis for a smart city, which always leads back to three guiding principles that should be prioritized: quality of life, economic competitiveness, and sustainability. 

The following factors as a starting point in order to develop a smart city. 

  • a technology-based infrastructure;
  • environmental initiatives;
  • a high functioning public transportation system;
  • a confident sense of urban planning and
  • humans to live and work within the city and utilize its resources.

Another point to mention is the relationship between the city and its government. How will a city adopt new sustainable practices without the help and approval from the government? It’s a two-way relationship that needs to be in place, and is a crucial aspect that needs to be considered before undertaking smart city initiatives. Everyone’s goals should be aligned – all parties should be on board with the technological developments, especially because all the work being done is happening with a third party, outside of the government, by the private sector. 

Main sectors in a Smart City

Smart energy

One of the primary goals of smart cities is using less energy, both in residential buildings as well as commercial buildings. As we have mentioned before, data collection in a smart city is also taken into consideration in order to both analyze and help make future improvements.  

One aspect that should be a focus is lighting, there’s no getting around it, we all use it everywhere we go. A few ways to incorporate smart lighting is by using LED lights, for example.

In a smart city, or any city for that matter, outdoor lighting provides its citizens with safe roads, inviting public areas, and provides additional security to their homes, businesses, and city centres. They are crucial  elements of any city infrastructure. Unfortunately, according to different reports, street lighting is one of the biggest electrical energy consumers, accounting for about 40 % of the total energy consumption in cities (The European PPP Expertise Centre (EPEC) 2010; European Commission 2013; Mohamed 2013). 

This shows that they are costly and contribute considerably to environment pollution. The production of electricity needed to power the street lighting systems significantly adds to carbon dioxide emissions (CO2, greenhouse gas) and nuclear dust. The costs of the electrical energy together with the environmental factors encourage municipalities to implement solutions to measure, analyse and reduce energy consumption in order to reduce spending and decrease maintenance costs (SungKwan Cho and Dhingra 2008; Li-jun et al. 2011).

Remote Lighting and Artificial Intelligence

Another extremely important smart city initiative is to implement remote control street lighting, combined with artificial intelligence to save on energy. 

Monitoring and analyzing energy usage is a key aspect. Overall energy usage is also part of a smart city. “Many may have experienced this already with the installation of smart meters at their homes. But with the rise of home solar power systems and electric vehicles, hardware and software technology will allow for the potential of better grid management, optimization of power production through different sources and distributed energy production. Furthermore, buildings that monitor their energy usage actively and report this data to utilities can reduce their costs. This will ultimately lead to lower pollution and much better efficiency as cities become more urbanized,” said Herman Chandi, co-founder of CommunityLogiq.

Transportation

Another factor in a smart city is having a  connected transportation system that works together, and assures easy mobility and safety. 

These initiatives are put in place in order to tackle challenges such as improving commute times, increase safety for riders and pedestrians, and offering alternative options for transportation. Electric vehicles are also part of smart city initiatives in order to promote green alternatives.

Smart cities use technology to connect vehicles in order to avoid traffic accidents and improve traffic congestion by exchanging basic safety information such as location, speed, and direction between vehicles within range of each other.  

Health

Smart cities focus on the health of its residents. How can they do this? By tackling the healthcare system within the city. 

This means taking a look at the systemic, existing challenges in healthcare, such as access to healthcare, inefficient or ineffective use of emergency facilities and providing healthcare to remote areas. 

There have been advancements in the health sector over the past few years, however, with the increasing population and urban lifestyle, it becomes critical to look after citizens in a more quick and efficient manner.

We have seen a shift in the last few years in relation to monitoring our own health. There has been an increasing demand of consumers to monitor their health by using wearable technology. This includes electronic devices that consumers can wear, like Fitbits and smartwatches, and are designed to collect the data of users’ personal health and exercise. US consumer use of wearables jumped from 9% in 2014 to 33% in 2018, according to Accenture.

For example, hospitals can use sensors to monitor air quality, a crucial aspect in the healthcare industry. In addition, a major evolution of IoT in healthcare is the use of electronic health records, which makes patient data more accessible in multiple locations.

Environment

Innovations help smart cities stay strong in the face of changing environmental, economic or political conditions. 

With the increase of natural disasters, it’s always a good idea to stay prepared. Smart technology can help cities take a more proactive approach when it comes to unpredictable events. 

For example, sensors in water can help cities better map floodplains. The data collected in sensors from other areas could be used to better predict where major fires are likely to happen – offering an opportunity for proactive prevention. 

Other benefits of a smart city

Another way to optimize the way a city functions is gathering real-time public transit information and building automation systems. This can lead to fewer GHG emissions, better air quality, energy saving, leakage detection, and control can support water conservation, and waste management. 

Smart City Capability and Opportunity

As discussed above, the development and installation of a Wireless Sensing Network (WSN) utilizing a wireless network solution allows for connectivity, collection, sharing and interpretation of data. There are several technological hurdles to overcome, specifically when collecting and transmitting data within urban environments. Signal loss, poor reliability, and data corruption are some key ones to note. These challenges are tackled head on with SpiderMesh, a fully cooperative wireless technology, specifically a LPWAN. 

A fully cooperative mesh network, SpiderMesh has virtually no limit in range, network size, excellent reliability, and robust self healing, repairing and deterministic network protocol. Additionally, deployment costs are low, resulting in an excellent marriage between data collection and low cost to collect data.  

Below we will examine and review several sensing opportunities and their respective capabilities. 

Sensors

Sensing capabilities have evolved greatly with an assortment of abilities. Connecting any sort of sensing equipment to a wireless network, you’ve now gained valuable, real time information directly from the source. This is made possible through the use of a Wireless Mesh Network. SpiderMesh’s LPWAN allows for the creation of a low cost WMN by building the sensing network from sensor location to cloud.

Sensors are a crucial component in a smart city, they are able to monitor a number of variables in different environments. These sensors will collect the required data and according to their readings, will act in accordance. There are a lot of options when it comes to sensors, it all depends on the goal. Some will monitor light, gas, pressure, temperature, humidity, and moisture, just to name a few. 

Geospatial Technology

In order to function efficiently, it’s crucial that a smart city have accurate, concise and detailed data. There are a lot of opportunities to help improve the lives of citizens using geospatial technology. You can receive relevant data about traffic (roadworks, traffic jams, optimal routes), road infrastructure (signs, potholes, road damages), public health (hospital infrastructure, spreading of the diseases) or important community practices (citizen initiatives, projects, and cultural heritage) can be easily visualized, organized and interpreted using interactive web maps.

Final Thoughts

Although the smart city concept is nothing new, there are still many more initiatives a city can implement in order to qualify as a smart city. As we have seen, the primary goals always remain the same. This means increasing the quality of life of its citizens, remaining economically competitive, and putting in place sustainable practices.
