5G is a core foundation upon which modern societies — their economies and their militaries — will all depend. This network of networks is critical to how industries compete and create value, how people communicate and interact, and how militaries seek safety for their citizens. 5G may be one of the most important networks of the 21st century. This is the very definition of critical infrastructure.

The primary goal of previous generations (3G and 4G) of mobile networks was to provide network users with fast, reliable mobile data services. 5G extends this reach, providing a wide range of wireless services to end users across multiple access platforms and multi-layered networks.

5G is actually a dynamic, coherent, and flexible framework consisting of multiple advanced technologies that support various applications. 5G uses a smarter architecture where the radio access network (RAN) is no longer constrained by the proximity of base stations or complex infrastructure. 5G leads the way towards a decentralized, flexible and virtualized RAN, with new interfaces creating additional data access points.

5G will have the ability to scale and adapt across an extreme variation of use cases such as uniform, fiber-like broadband everywhere (not just higher peak data rates) services; ultra-reliable, mission-critical services such as controlling the power grid or remote medical procedures (where failure is not an option).

The vision for 5G is to create a unified platform that will support the connectivity needs of the future. 5G is expected to:

5G is a key part of the intelligent era because it connects billions of devices and enables the Internet of Things (IoT). 5G is expected to have a significant impact on society, including in healthcare, transportation, and smart cities.

5G networks are part of a nation's critical infrastructure and are designed to be flexible enough to accommodate a wide range of use-case scenarios. To achieve this flexibility, network intelligence and security must be managed through the network. This further increases the complexity of the network. 

Wireless 5G uses a smarter architecture that is no longer limited by distance from base stations or complex infrastructure. 5G is the next generation of cellular networks that promises to meet the insatiable demand for data rates and interconnecting billions of smart devices, enabling not only human-centric but also machine-centric traffic. 

Driven by the rapidly growing demand for responsive connectivity, the industry is working hard to define and introduce next-generation mobile standards.
