5G is the current cellular generation standard, built primarily on 3GPP 5G system and the NR air interface (Release 15).
5G is the fifth generation of cellular network technology and the successor to 4G. In commercial use, it mainly refers to mobile networks built on the 3rd Generation Partnership Project (3GPP) 5G system and its New Radio (NR) air interface, first specified in 3GPP Release 15. 5G was developed to meet the ITU’s IMT-2020 framework for fifth-generation mobile systems, aiming to deliver much higher performance and support for new communication needs. The purpose of 5G is to improve speed, capacity, and responsiveness while enabling flexible network management. Compared with 4G, it is designed for higher data rates, greater network capacity, lower latency, better support for dense device deployments, and more adaptable core-network features. 5G networks can be deployed using different spectrum ranges (low, mid, and high bands) and different architectures (non-standalone mode using existing LTE cores, or standalone mode with a dedicated 5G Core). 5G also supports capabilities such as network slicing and edge computing, enabling services like enhanced mobile broadband, ultra-reliable low-latency communications, and massive machine-type communications for applications ranging from consumer connectivity to industrial automation and public services.
5G is the current cellular generation standard, built primarily on 3GPP 5G system and the NR air interface (Release 15).
Its purpose is to meet IMT-2020 goals by delivering higher data rates, capacity, and lower latency, plus support for dense and machine-centric connectivity.
5G can be deployed in non-standalone mode (with LTE core) or standalone mode (with dedicated 5G Core), and it uses low-, mid-, and high-band spectrum with performance depending on frequency and design.
5G supports advanced features such as network slicing and edge computing, enabling major use cases like eMBB, URLLC, and mMTC.
