nnThe ideal speed of 5G is 10 gigabits per second (Gbps) which is 100 times the speed of 4G!nn nn5G – the 5^th generation mobile network is the upcoming solution to network latency issues. What is 5G and how is it better than the existing network is the question running in everyone’s mind. This blog explains 5G, its benefits and use cases.nn nnWhat is 5G?nnThe next-generation of telecom networks – 5G hit markets at the end of 2018 and has been expanding ever since. 5G technology is a breakthrough in the field of networking and communication. It is the successor to the conventional 4G LTE(Long Term Evolution). 5G rollout is progressing along two dimensions – an evolutionary development of the air interface known as 5G NR (New Radio) and a fundamental reconceptualisation of the core network architecture.nn5G offers the potential to transfer data with lower latency, stronger signal strength, swiftly and securely. 5G achieves this by utilising a different type of radio wave called the millimetre wave (between 30GHz and 300GHz), which helps it transfer data much quicker than 4G.nnBeyond speed improvement, 5G has the potential to unleash the vast IoT (Internet of Things) ecosystem where networks can establish communication for billions of connected devices, with optimal speed, latency and cost.nn nnA quick recap of wireless telephone technologynn1G, the first generation of telecom networks was introduced in the year 1979. Mobile telecommunications has drastically evolved over the last four decades. 1G, 2G, 2.5G, 2.75G, 3G, 3.5G, 4G and 4G LTE are the advancements in the generation of mobile networks.n

The widespread 4G towers use radio wave frequencies to transmit data.nn5G requires a similar setup – 5G devices running on 5G networks transmitted by 5G towers. The prime difference which makes 5G better is that it utilises much shorter radio waves called the millimetre waves (mmWave).nnThe shorter frequencies have larger bandwidth. It implies that 5G can transmit and receive large amounts of data much quicker than 4G and 4.5G (LTE advanced).nnBeyond data speed improvements, 5G addresses cutting-edge IoT and critical communication use cases. 5G offers extremely low delay between transmitting and receiving a signal. 4G has a latency of 200 milliseconds; 5G has brought it down to 1 millisecond. Its low latency supports real-time interactivity for services using the cloud.nnIt comparatively consumes low power which will allow objects on the network to stay connected for months without human interference. 5G networks are designed to bring the level of performance needed for the IoT ecosystem.nn5G transmissions are more powerful and consistent than 4G within their range despite significant network activity. 5G can handle 100 times more devices than 4G.nn nn5G Use CasesnnLike its predecessors, 5G is entering the market with a new set of use cases. 5G will set its focus on IoT and critical communications.n
