What technology allows smartphones to connect to the internet at high speeds?

In telecommunications, 5G is the fifth-generation of cellular network technology, as the successor to the fourth-generation (4G), and have been deployed by mobile operators worldwide since 2019. Compared to 4G, 5G networks offer not only higher download speeds, with a peak speed of 10 gigabits per second, but also significantly lower latency, enabling near-instantaneous communication through cellular base stations and antennae. There is one global unified 5G standard: 5G New Radio (5G NR), which has been developed by the 3rd Generation Partnership Project (3GPP) based on specifications defined by the International Telecommunication Union (ITU) under the IMT-2020 requirements.
