Thanks to the internet of things (IoT), artificial intelligence (AI), cloud computing, and fast communication networks, cities are getting smarter in how they operate, deliver services, and support residents and businesses. The continued deployment of 5G networks, with their substantial increases in speed, bandwidth, and data throughput, will only serve to accelerate the development of smart cities throughout the world. In this blog post, I¡¯ll take a look at how smart many cities have already become and what we can expect to see on the horizon as 5G networks get rolled out.

In Singapore, a vision called Smart Nation aims to collect data from throughout the city-state via sensors that are linked to aggregation boxes, making it easier for the appropriate agencies to conduct analysis and deliver services accordingly. Dubai is in the midst of a multi-year plan to digitize all government services, covering areas including transportation, electricity, infrastructure, and communications. Oslo is deploying sensors widely in its buildings to control lighting, heating, and cooling¡ªa part of the Norwegian capital¡¯s goal to reduce emissions by as much as 95% by 2030. These cities are among the many that are .

High Speed, Low Latency, and Edge Analytics

The fifth generation of cellular technology for network communications, 5G delivers up to 100x the speed and 10x less latency than the preceding 4G technology. Theoretical speeds for 5G downlinks can go up to 20 Gbps and for uplinks, speeds can reach up to 10 Gbps (with real-world speeds of up to 100 Mbps for downloading and up to 50 Mbps for uploading). Under ideal conditions, latency in connecting to the network from a device typically clocks in at 4 milliseconds, though some critical applications can achieve latency as low as 1 millisecond. International Data Corporation (IDC) projects that the . By enabling many more simultaneous connections to IoT devices, 5G technology will be a powerful force for smart cities.

While 5G technology solves some of the bandwidth and latency challenges of deploying smart city capabilities, other difficulties remain. One of the most important is security, and the focus towards this will depend on each given application. At what point does the public infrastructure think that security is a big enough deal? How valuable is the data involved? Will people care if it is stolen? Whether the application is in the domain of public safety, healthcare, or logistics will likely influence how much attention is paid to security. Silicon chips integrated with root of trust and public/private keys with random number generation technologies are widely available for IoT designs. And we¡¯re starting to see more movement in this area, with organizations like PCI-SIG adopting security into  used to connect to remote radio heads and baseband radio (PCI Express? 5.0 features integrity and data encryption cryptographic features). But there¡¯s certainly room for more, as an entire root of trust from design through implementation is required to safeguard smart city applications.

Network infrastructure is another area that cities will have to address. The concept of private wireless networks is becoming more important, as these networks provide the highly reliable, low-latency connectivity that mission-critical applications demand. The combination of 5G and edge computing can prove to be a resilient mix for real-time decision-making¡ªeven autonomously when you consider the impact of AI. Edge analytics paves the way for wide deployment of vehicle-to-vehicle (V2V) and vehicle-to-everything (V2X) systems in autonomous cars, more proactive public safety measures, more efficient waste management and fleet management, and better resource conservation.

Powering Smart Cities from Silicon to Software

At the heart of all of these innovative applications are complex semiconductors and sophisticated software. Because the design and verification of the chips is more complicated, as is the development of the software, having a portfolio of electronic design automation (EDA), IP, and software integrity solutions is essential.
