The term “6G” refers to the sixth-generation wireless network and is the successor to 5G cellular technology. With 6G, networks will use higher frequencies than 5G networks and provide substantially higher capacity and much lower latency. Both humans and machines will be the primary users of 6G and 6G will be characterized by the provision of advanced services such as truly immersive extended reality (XR), high-fidelity mobile holograms, and digital replica.
