No single person or organization claims the invention of 5G. It is the successor to 4G and is currently being deployed in many parts of the world. 5G offers higher speed and lower latency than its predecessors, as well as improved support for more devices. 5G was developed by a consortium of telecom companies, including Ericsson, Nokia, Qualcomm, and Samsung. It is based on the LTE standard and uses OFDM (orthogonal frequency-division multiplexing) for downlink transmissions.
