5G networks aim to address limitations of 4G by providing lower latency, higher connection density, and a more consistent quality of experience. 5G will focus on use cases like dense urban areas with high traffic volumes, open air festivals with many connected devices, and virtual reality applications requiring very high data rates. Both sub-6GHz and millimeter wave spectrum will be used to meet requirements like ultra-reliable low latency communications, massive machine type communications, and enhanced mobile broadband. 5G technologies like massive MIMO, new waveforms, and network functions virtualization will help mobile networks evolve to meet growing demands from the Internet of Things, augmented and virtual reality, and other innovative services.
