5G Technology – 01

Timeline; Features; Applications and Challenges 5G network is the next generation of wireless communication. It’s much faster and able to connect with more devices than the existing 4G LTE network. China is the first country to officially announce its entry to the 5G era. In this article, we are providing you with complete details on 5G Technology which is important for UPSC Exam.
  • The first generation of mobile network (1G)-
    • It was launched for the first time by Nippon Telegraph and Telephone in Tokyo. By 1984 it was rolled out in the whole of Japan.
    • By the late 1990’s 1G, also appeared in the US, Canada and UK.
    • It only involves call functions, but have problems in the form of high cost, continuous network disruption, poor coverage and poor sound quality.
    • These drawbacks paved the way for the arrival of 2G. The maximum speed of 1G was 2.4 Kbps.
  • 2nd Generation network
    • In 2G people could send messages(SMS), picture messages and multimedia messages(MMS) on their phone. It led to a cultural revolution in the society.
    • The main problem with 2G was its sluggish speed of only 50Kbps.
  • 3G Technology–
    • In 2001,3G was launched by  NTT DoCoMo. It increased data transfer capabilities and brought new services like video streaming, Voice over IP and video conferencing.
    • 3G made it possible to have international calls. The maximum speed of 3G was 2Mbps.
  • 4G LTE
    • It provided with high speed and wide coverage. It was launched in 2009 and it enables features like virtual reality.
    • Most mobile phones at present support both 4G and 3G technologies.     
  • Features of 5g-
    • High average speed of downloading-20Gbps, as compared to 20Mbps from 4g
    • The latency of 1milliseconds.
    • Spectrum- 2.3GHz to 24 GHz and more. In the 4G spectrum, the range is 800MHz to 2.6
    • Wider connectivity
Application of 5g
  • Faster data processing– 5G has a latency rate of 1 millisecond and a speed range of 20Gbps and more. Thus data collected by various source can be processed at a fast pace.
  • High-speed mobile network- 5G will reduce buffering and enhance the download speed on our mobiles. It’ll also help in good quality video calling and conferencing.
  • Internet of Things- 5G will boost up development in the field of IoT.
  • Artificial intelligence- 5G has added advantage for machine learning, robotics and other programming modules. It can provide faster processing of data.
  • Education- Due to Covid-19, Online learning has gained a lot of momentum. But the speed of the internet set up a big hurdle in education. 5G can help in faster connectivity and better learning experience. It’ll also open new avenues for learning.
  • Health sector- 5G will help in the field of Telemedicine and biotechnology. It will help in spreading access to medical services to far fledged areas.
  • Employment Opportunities- 5G will open new areas of employment in various sector like the I.T. sector, construction sector and Cyber sector. According to an estimate, it can lead to employment opportunity for almost 5 crore youth in India.
  • Government Services- 5G can help in better access and last-mile access to Government services for the citizens. It will help in faster public grievance redress and ensure transparency and accountability in government services.
  • Global competitiveness- India can boost it’s Make in India programme and also compete with China in terms of 5G rollout. To meet the pace with global technology India needs to speed up its 5G research.
