Weekly Takeaways-February 23, 2023

Updated: Jun 19, 2023

Theme of the Week

What do you call a Smart City without PNT? A city. Most definitions of a Smart City talk about a city that leverages connectivity for the Internet of Things (IOT), transportation, sustainability, and energy usage. But this technology already exists. So what is the city of the future really lacking? This: Self-driving vehicles, air mobility, flying taxis, and delivery drones can reduce traffic and emissions. But this won't happen without better navigation infrastructure. Vehicles are already being outfitted with cameras and lidar for proximity sensors. But these prevent collisions or spatial awareness - they don't provide guidance. And GPS and other space-based systems can’t provide effective navigation in urban canyons, tunnels, and parking garages. One solution was described in 2008 by Steve Jobs: in large cities, we are surrounded by wi-fi routers and cell towers that are natural beacons. The next step is to provide position and timing over these beacons as part of a larger mobility network. But these beacons need to be accurately – and securely – synchronized. Timing not only impacts the position accuracy, but in a future of flying cars you don’t want infrastructure that can be easily hijacked. Last Week's Theme: The Server Lights Are Big and Bright

The More You Know...

Quantumania isn't just the title of a superhero movie - in the real world there has been a lot of interest in quantum technologies recently. The incredible applications enabled by quantum technologies has created a sort of global quantum arms race. By some estimates (including recent McKinsey and Deloitte reports) China was the leader in global quantum funding. In the US, funding from the National Quantum Initiative Act led to a renewed government focus and new quantum testbeds in Washington DC, Chicago, Tennessee, and New York. This race is so critical that The World Economic Forum raised concerns about a growing quantum divide, since "quantum technology will exponentially accelerate the Fourth Industrial Revolution."
