1 Cellular networks

Cellular networks are wireless networks that use base stations and mobile devices to communicate over licensed spectrum. Cellular networks can provide wide-area coverage, high data rates, and reliable service for smart city applications that require constant and secure access to the internet or cloud services. For example, cellular networks can support smart parking systems that use sensors and cameras to monitor the availability and occupancy of parking spaces, and send real-time information to drivers and authorities.

While robust, cellular alone may not handle future smart city complexity. Experts suggest hybrid networks with LPWANs for low-power sensors & mmWave for ultra-fast data streams.

2 Ad hoc networks

Ad hoc networks are wireless networks that do not rely on any fixed infrastructure or central coordination. Instead, they use peer-to-peer communication among nodes that can dynamically join and leave the network. Ad hoc networks can provide local-area coverage, low latency, and self-organization for smart city applications that require spontaneous and collaborative interactions among devices. For example, ad hoc networks can support smart traffic lights that use vehicle-to-vehicle and vehicle-to-infrastructure communication to optimize the traffic flow and reduce congestion and emissions.

These are more like local hotspots, formed on the fly by devices connecting directly. They're great for short-range, low-latency interactions, like smart traffic lights communicating with each other to optimize traffic flow in real time.

3 Hybrid networks

Hybrid networks are wireless networks that combine the advantages of cellular and ad hoc networks. Hybrid networks can provide seamless connectivity, scalability, and flexibility for smart city applications that require both wide-area and local-area communication, as well as adaptation to changing environments and user needs. For example, hybrid networks can support smart health care systems that use wearable devices and mobile phones to collect and transmit health data, and use ad hoc communication among nearby devices to provide emergency assistance or social support.

4 Challenges and opportunities

Cellular and ad hoc networks face several challenges and opportunities in improving smart city services. Some of the challenges include interoperability, security, privacy, and energy efficiency of the wireless devices and protocols. Some of the opportunities include integration, innovation, and participation of the wireless technologies and stakeholders. For example, cellular and ad hoc networks can integrate with other smart city technologies, such as sensors, cloud computing, and artificial intelligence, to create more intelligent and efficient solutions. They can also foster innovation and participation by enabling new applications, business models, and user involvement.

5 Future trends and directions

Cellular and ad hoc networks are constantly evolving and advancing to meet the growing demands and expectations of smart city services. Some of the future trends and directions include 5G and beyond, internet of things, and edge computing. 5G and beyond are the next generations of cellular networks that aim to provide ultra-high speed, low latency, and massive connectivity for various smart city applications. Internet of things is the concept of connecting billions of devices and objects to the internet and each other, creating a network of smart things that can sense, communicate, and act. Edge computing is the concept of moving the computation and storage closer to the edge of the network, reducing the dependence on the cloud and improving the performance and efficiency of the smart city applications.
