5G is the successor to 4G and is commonly implemented using 3GPP 5G System and the NR (New Radio) air interface.
5G is the fifth generation of cellular network technology and the successor to 4G. In commercial use, “5G” typically refers to mobile networks built around the 3rd Generation Partnership Project (3GPP) 5G system and its New Radio (NR) air interface, first specified in 3GPP Release 15. It was developed to meet the ITU’s IMT-2020 framework and is designed for higher performance and new capabilities such as network slicing and ultra-reliable low-latency services. Compared with 4G, 5G is designed to deliver higher data rates, greater capacity, lower latency, and more flexible network management, while also supporting dense deployments of devices. 5G networks can be deployed in non-standalone mode (using existing LTE/4G core infrastructure) or standalone mode with a dedicated 5G Core. 5G is deployed alongside 4G and is expected to coexist with it for many years, with different frequency bands (low, mid, and high/mmWave) used to balance coverage and speed.
5G is the successor to 4G and is commonly implemented using 3GPP 5G System and the NR (New Radio) air interface.
5G improves on 4G with higher data rates, higher capacity, and lower latency, plus support for dense device connectivity and flexible management.
5G can run in non-standalone mode (with 4G/LTE core) or standalone mode (with a dedicated 5G Core), and it coexists with 4G for years.
5G performance and coverage depend strongly on the spectrum used (low-, mid-, and high/mmWave bands) and on network design and device capabilities.
The current generation of cellular network technology designed to succeed 4G and meet IMT-2020 requirements.
The previous generation of cellular networks that 5G is designed to replace and improve upon.
The standards body that specifies the 5G system and its New Radio (NR) air interface for commercial deployments.
The 3GPP-defined radio interface used by 5G networks for communication between devices and the network.
A 5G deployment mode that uses an existing LTE/4G core network infrastructure.
A 5G deployment mode that uses a dedicated 5G Core network.
The service-oriented core network for standalone 5G that separates control and user planes and replaces the 4G EPC approach.
