5G is a wireless technology that is offering a staggering increase in transmission bandwidth, theoretically 10 gigabits per second (GBit/s). It is the fifth generation of cellular mobile (wireless) communications. It succeeds the 4G (LTE/WiMAX). 5G network speed will eventually be 20 G/bps or higher and will have a latency that is mere milliseconds. The 5G platform brings a high data rate, reduced latency, energy savings, cost reduction, higher system capacity and massive device connectivity. While 4G, was synonymous with unparalleled speed, 5G will be considered synonymous with intelligence.
5G will enable people, machines, automobiles, city infrastructure, public safety and more to be connected to each other. Despite concerns regarding 5G being power-driven, one of the recent research projects conducted in Spain and Brazil indicates that it might be up to 90% ore efficient then 4G network in terms of energy consumption.
5G will unlock higher bandwidth, near real-time responses, the IIoT ( Industrial Internet of Things), and mission critical products and applications. It has the potential to significantly improve productivity, optimse service quality and reduce costs, leading to increased economic output
Another prominent application of 5G is going to be network slicing. It allows telecommunication providers to run several virtual networks within one physical connection in addition to its low latency. 5G will enable providers to ‘slice’ the network, which means that different networks and virtual layers provided will add value to the business. Network slicing will make it possible to create new business models through data monetisation.
Nearly $1 trillion will be spent on 5G between 2019 and 2025, according to GSMA (Global System for Mobile Association) Intelligence. Over the next seven years, 5G networks will mature across the US, China, Japan, the UK and the European Union. By 2025, there are likely to be 1.4 billion 5G connections and 5.5 billion 4G connections globally, according to GSMA Intelligence.
In India, the 5G launch might happen in 2021-22, with 5G auctions likely to be held in 2021.
Pilots for next-generation networks, called 5G Enhanced or 6G, will start towards the end of the next decade.
