5G is much faster, more responsive, and more customizable than 4G and is expected to be fundamental to the advancement of new technologies such as IoT, AI, VR, and self-driving cars. To match human-like reflexes, autonomous vehicles need to be able to read their environment and sift through enormous amount of sensor data in real-time — which 5G makes possible with its reduced latency and ultra-fast network speed. But when will all of this actually happen? Well, it already is. Watch the video above and follow TNW’s visit to Seoul, which is fast becoming one of the world’s first truly smart cities. Seoul is leading the way in 5G experimentation by providing a testbed for new products and services. Interested in seeing more of Seoul’s vibrant tech scene?
