5G is the 5th generation of wireless technology that will offer faster speeds, increased bandwidth, and lower latency compared to previous generations. It aims to provide speeds over 1 Gbps, support a vastly greater number of connected devices, and enable new applications. Key technologies that will enable 5G include massive MIMO, ultra-dense networks, new multiple access techniques, support for all spectrum types, and new network architectures based on network function virtualization and software-defined networking. 5G will enable new use cases like connected vehicles, telemedicine, and the Internet of Things by supporting requirements for low latency, high reliability, and large connection densities.
