According to a paper published by the United Nations, the world’s population is projected to grow to reach 9.1 billion people in 2050 – 2 billion more people than there are today. The current migration of the world’s population to urban centers will continue at an accelerated pace. In fact, projections estimate that 70 percent of the world’s population will reside in urban areas, compared to 49 percent today.
These urban centers will need to strike a balance between geographical sprawl and an increased scarcity of resources, such as arable land, water and energy. Urban planners are rapidly adopting technology to meet these challenges, creating smart cities to maximize resources and improve the quality of life of exploding populations. These smart cities are deploying sensors to monitor resource levels, as well as the movement of people and goods. Sensors using millimeter-wave (mmWave) radar technology will become prevalent because of its unique characteristics of range, velocity and angle detection with high accuracy, long distance and robustness of operation independent of environmental conditions.
Let’s examine the application of mmWave sensors in smart cities.
