5G Technology Future Scope in 2021


5G Technology Future Scope is the trending topic in the year 2021. This subject is often in leading Newspapers, TV debates, Magazines, Journals, etc. The world is rapidly developing and technology is continuously changing.

Whether be a person or a state, it can stand only and only if it can cope with changing technology. Now before we focus on the future scope of 5G technology, let us understand what is 5G technology.

What is 5G ?

It is the fifth generation of mobile network technology after 1G, 2G, 3G, and 4G. This latest generation aims to bring man, machine, objects, and devices on one platform and connect them virtually.

According to GSM Association, this technology may reach 1.7 million subscribers by 2025. This service is launched in 62 countries by 162 mobile operators till March 2021.

The biggest advantage of this tech is that it has a large bandwidth and thus it can download and upload very fast. The speed may go up to 10 gigabits per second, about 100 times faster than 4G.

First Generation

1G, the first generation of telecom networks (1979), let us talk to each other and be mobile

5G Technology Future scope

Second Generation

2G digital networks (1991) let us send messages and travel (with roaming services)

5G Technology Future scope

Third Generation

3G (1998) brought a better mobile internet experience (with limited success)

5G Technology Future scope

3.5G brought a truly mobile internet experience, unleashing the mobile apps ecosystem

5G Technology Future scope

Fourth Generation

4G (2008) networks brought all-IP services (Voice and Data), a fast broadband internet experience, with unified networks architectures and protocols

5G Technology Future scope

4G LTE ( for Long Term Evolution), starting in 2009, doubled data speeds

5G Technology Future scope

Fifth Generation

5G networks expand broadband wireless services beyond mobile internet to IoT and critical communications segments

Technology Behind 5G

 5G is based on OFDM (Orthogonal frequency-division multiplexing), a method of modulating a digital signal across several different channels to reduce interference. It uses 5G NR air interface alongside OFDM principles. 5G also uses wider bandwidth technologies such as sub-6 GHz and mmWave.

5G will bring wider bandwidths by expanding the usage of spectrum resources, from sub-3 GHz used in 4G to 100 GHz and beyond. It can operate in both lower bands (e.g., sub-6 GHz) as well as mmWave (e.g., 24 GHz and up), which will bring extreme capacity, multi-Gbps throughput, and low latency.

What Can 5G do?

As described above, this technology will enhance the network speed manifolds. The high speed will help devices with the network in real-time. Noe let us see how this will benefit and improve our society.


  • Sensors and wearables connect patients and doctors in remote hospitals.
  • Drones can bring the agriculture industry to a new era.
  • More active emergency services in the time of the accident or natural disaster.
  • More connected vehicles sharing data to prevent road collisions
  • Smarter electricity grids for greatly reduced unnecessary wastage of energy.


5G can enhance ease of doing business with high efficiency.

  • Digital connectivity with devices can warn about real machinery faults ahead of time.
  • Production lines autonomously reacting to supply and demand.
  • Logistic networks autonomously routing goods based on real-world conditions.
  • Remote access to powerful robots and vehicles for improved safety in risky environments.
  • Increased use of IoT in agriculture to efficiently grow crops.

5G Technology Future Scope in India

5G is set to have a hugely beneficial impact on India and it is going to set a new milestone in India. To have practical effects on the ground, trial on the new technology has already started. To mention without a doubt that Ericsson, Huawei, Samsung is working significantly with communication service providers.

Developments in 5G

According to the GSM Association, a trade body that represents the interests of mobile network operators worldwide, the following developments have taken place in India at this time on the 5G front: 

1. Bharti Airtel and Huawei have successfully conducted India’s first 5G network trial under a test setup at Airtel’s network experience center in Manesar, Gurgaon, achieving a user throughput of more than 3 Gbps. Bharti Airtel has signed a memorandum of understanding (MoU) with Nokia and Ericsson to support the company in its preparations for 5G rollout.

 2. Vodafone Idea has also proposed 5G trials with multiple vendors, including Huawei and Ericsson. 

3. Samsung will conduct 5G field trials in New Delhi in 2019 and is working closely with the DoT. The company is also likely to be one of Reliance Jio’s partners for its 5G field trials. 

4. Last but not least, Reliance has a clear vision to enforce 5G in India as soon as possible. To quote Mr. Ambani-” I assure you that Jio will pioneer the 5G revolution in India in the second half of 2021. It will be powered by the indigenous-developed network, hardware, and technology components,”
