What is 5G? Everything you should know

5G is the latest and next generation of a cellular network for mobile internet connectivity, which is much more faster than its successor, the 5G network succeeds the 4G, 3G and 2G systems network, from where we have the first generation of cellular network to this latest mobile internet network. The 5G performance at a high data rate as much as it offers higher system capacity and massive device connectivity.

According to Wikipedia the first phase of the 5G specifications are Release-15 will be completed by April 2019 to accommodate the early commercial deployment.

While the second phase will officially and expected to launch in April 2020 for submission to International Technology Union (ITU) across the world, the 5G network will still be able to work alongside the 4G, 3G, and 2G technology.

The 5G network is expected to have a download speed of 1GBps, due to the speed of the network, and a theoretical peak download capacity of 20 gigabits. 5G network promotes faster speeds and low-latency data transfer on edge devices. 5G is also expected to be widely utilized for private networks with applications in industrial IoT, enterprise networking, and critical communications. As the 5G network will be a big part of, The Internet of Things, the 5G will be needed to carry and work on larger data to produce smart cities and connected world. As connected devices are rapidly increasing.

However, the speeds in early deployments, using 5G NR software on 4G hardware, are only slightly higher than new 4G systems, estimated at 15% to 50% faster, which means to say that the 5G will be 50% faster than the 4G. 5G NR can include lower frequencies, below 6 GHz, and mmWave, above 15 GHz.

Development of 5G is led by companies such as Qualcomm, Huawei, and Intel for modem technology and Nokia, Ericsson, ZTE, Cisco, and Samsung for infrastructure. The first country that will first install the first 5G network will be the US, South Korea, China, and UK. The world-first service of 5G was in South Korea, as the South Korean telecoms deployed it all at once on 1 December 2018, according to Wikipedia.

All companies are already making their products compatible with the 5G technology. The maximum achievement of the peak data rate is 20 Gbit/s. The achievable data rate across the user experience on coverage area is said to be 1 Gbit/s. The latency of a radio network to packet travel time is 1ms. The maximum speed for handoff and QoS in mobility required 500 km/. The total number of devices per unit area is 10 raised to the power of 6 /km2. The energy efficiency of data sent and received per unit energy consumption (by device or network) is equal to 4G.
