One of the most frequently posed IoT testing interview questions, be ready for it. The impending proliferation of 5G networks may have several different effects on the Internet of Things (IoT):  Supporting more sophisticated use cases is made feasible by having a higher bandwidth and faster throughputs. This is particularly true for use cases that need shorter reaction times, such as automated public transit or traffic control systems.  Because organizations have the ability to disperse more sensors, they can collect a wider range of information about environmental factors or the behaviour of equipment. This leads to more comprehensive analytics and a greater capacity to automate operations on both the industrial and consumer levels.  The Internet of Things might be enabled on a more extensive scale in regions where it would otherwise be impossible to accomplish with the aid of 5G, which would be beneficial to businesses like as agriculture and healthcare.  Establishing smart cities, which call for a greater saturation of Internet of Things devices, is made simpler by the quicker throughput and the capacity to handle data from a greater number of sensors.  5G might help manufacturers improve their inventory tracking throughout the product's lifespan, as well as improve their ability to govern processes and optimise operations.  5G makes it possible for businesses and governments to react to a wider variety of catastrophes, including medical emergencies, pipeline breaches, fires, traffic accidents, weather events, and natural disasters, in a more prompt and effective manner.  5G has the potential to improve automobiles in a number of ways, including making them safer, easier to maintain, and more economical with fuel, while also bringing the concept of driverless vehicles closer to becoming a reality.
