What is 5G all about?

Simply speaking, it is the 5th generation of wireless technology. The 5th generation technology has been envisioned as bigger, faster, better.  5G architecture is built on a much higher next-generation technology plane with the premise to connect everything and everyone – people, buildings, cities, sensors, smartphones, robots, drones. As compared to the existing wireless technology, it will have higher data rates, reduced latency, higher capacity system, energy savings and cost reductions. It will bring new capabilities and create opportunities for society and business. Here is some of the excited chatter about 5G:

“Connected cars will shape the future of individual mobility, and next-generation mobile networks will take car‑to‑x connectivity to a new level.” – Alfons Pfaller, Head of Infotainment Development, AUDI AG

“The adoption of 5G will be even faster than what we saw on 4G, which was already fairly fast,” said Ignacio Contreras, Qualcomm’s director of marketing

“5G will be the post-smartphone era,” said Robert J. Topol, Intel’s general manager for 5G business and technology. “Phones are the first place to launch because [they’re] such an anchor in our lives from a connectivity standpoint.” 

“5G is one of those heralds, along with artificial intelligence, of this coming data age,” said Steve Koenig, senior director of market research for the Consumer Technology Association.

What is 5G capable of?

Imagine living in a world where people, gadgets, buildings, and infrastructure talk to each other. In this world, doctors can conduct surgeries from thousands of miles away; cars drive on their own; buildings, factories and cities can interact with you; and you can shop and watch live sports events in VR!

Now open your eyes, because we’re not talking about a sci-fi movie here. Rather, this is what our world will become thanks to 5G – hyper-connected, secure and experiential on an unimaginable scale.

Fascinating, right?

What makes 5G different?

So far, with technologies like 4G, we have mostly imagined connectivity as human-to-human, or human to the internet. But, with 5G, that will no longer be enough.

The next natural evolution of connectivity is to not only connect everyday machines and devices to humans but machines to other machines. In fact, the entire promise behind 5G lies in connecting our entire environment with each other! With the number of connected devices globally set to triple by 2030 to 25.4 billion, terms like Internet of Things (IoT), Virtual Reality (VR), and Artificial Intelligence will no longer be just fanciful connotations of what will happen in the future. All these amazing experiences will be unlocked on the back of 5G.

According to 3GPP (3rd Generation Partnership Project), 5G delivers value by enhancing three major applications

  1. Enhanced mobile broadband (EMBB) – Faster data rates, wider network coverage areas, enhanced ultra-HD video streaming 
  2. Ultra-reliable, low latency communication (URLLC) – Increased communication speed and quality in critical functions such as robots and drones

Massive machine-type communication (MMTC) – Automatic generation, processing and transmission of data between machines with almost zero human intervention

Differences between the previous generations of mobile networks and 5G

Chart for various generations of wireless technology

Let us chart out the journey of various generations of wireless technology to fully understand the phenomena of the fifth generation:

1G or the first generation of mobile networks was built in the 1970s and 80s and was analogous, carrying only voice data. They have carried over radio waves and were unencrypted. Japan started the 1G revolution. The drawbacks of 1G were poor coverage and sound quality, no compatibility between systems and unencrypted voice.

2G came into existence in the 1990s. The calls were digital and encrypted. Higher quality data could be transferred. People could send text, picture and multimedia messages. This led to a telecommunications revolution. Mobile cell towers came into being and consumers and businesses adopted them with speed. Smartphones came into being.

3G was built in the early 2000s. With this generation, users could access data from any location in the world as web connectivity were standardised. This was 4 times faster than 2G. In 3G, data transfer capabilities increased and video conferencing, video streaming, voice quality. Blackberry was launched with this generation’s features. iPhones came into being around 2007 and with 3G technology made smartphones a necessity over a luxury item.

4G: Apple, Google, Facebook really ushered in the 4G technology adoption. 4G made high-quality video streaming a reality for consumers. Currently, the technology being used mostly, 4G technology enables high-definition videos, conferencing, gaming services. Switching from 2G to 3G was simple with a mere change of sim cards. However, for 4G, a change in mobile devices is needed.

5G: We are at the cusp of the 5th generation revolution. This generation promises higher speed, reduced latency, energy savings and higher capacity systems. The superior connectivity offered by 5G aspires to equal access to the network regardless of location or social status in society. 5G offers the possibility of innovations such as remote surgeries, telemedicine, self-driving cars, smart cities, smart buildings and smart factories, virtual reality experience while gaming, shopping and viewing sporting events. It looks to expand wireless services from the internet to the Internet of Things and communication sectors.

How is 5G better than 4G?

Advantages of 5G over 4G

For starters, think of 5G as not the natural evolution of 4G but a new, more advanced technology itself.

While earlier generations used cell towers to transmit signals, 5G will use small cell technology. This means that carriers will deploy high band 5G smalls cells in multiple locations. Additionally, as part of its OFDM coding, 5G technology is built to use 100 to 800 MHz channels instead of 4G’s 20 MHz. Remember, the higher the channels, the more the download speed. Thus, 5G is 20 times faster than the previous generation, has much lower latency and tremendously improved reliability. It allows a higher number of users to connect simultaneously, while lower latency will ensure greater download speed.

5G in India

Owing to increased mobile and broadband penetration, India is already in the midst of a digital revolution. But once the future of 5G in India comes to fruition, it will spearhead this revolution and transform the productivity, experiences and aspirations of a billion people in a blink of an eye.

Today, ‘when is 5G coming to India’ and ‘is 5G in India already’ are two of the most pertinent questions that all informed citizens have been asking. Although the central government envisaged a viable, robust 5G network in India by 2018, inadequate spectrum availability, exorbitant spectrum pricing, poor development of test cases, deficient back-haul capacity, low reach of optical fibre across the nation and delays in planning have pushed the date to the second half of 2021.

Despite all these issues, the number of 5G-connected devices in India is forecasted to be around 350 million by 2026, as per Ericsson. This means that the nation is ready to embrace the next-gen technology soon, with companies involved in 5G in India such as telecom giants like Airtel and Jio ready to commercially roll out 5G by October 2021.

At present, all industry stakeholders in the country, including 5G infrastructure companies in India, are actively involved in readying the necessary 5G-compliant ecosystem in wake of the roll-out. The Department of Telecom is focused on R&D around PPP projects, testbeds, pilot roll-outs and standards formulation. They are also working with TRAI and other stakeholders on a Spectrum Management Framework while encouraging collaborations between start-ups and ICT companies. Simultaneously, Indian telcos and OEMs are conducting 5G deployment feasibility studies. Indian IT sector has come up with its own set of solutions and 5G applications to support this new era of connectivity. In terms of fibre penetration to enhance 5G reach and distance, India plans to increase fibre backbone to 2.5 million km by 2022, with 300,000 km of fibre planned under the BharatNet programme for rural areas. 

So, how will 5G change India?

The answer is simple: kickstarting the Industrial Revolution 4.0 to bring us technologically on par with global leaders like China, Japan, the US and Western Europe. As the industry develops hundreds of 5G use cases, many of the applications like IoT, smart cities and automation will enable us to transform the country’s manufacturing, agriculture, healthcare, education, IT, work and living infrastructure. Reasonably, many emerging companies to benefit from 5G in India will belong to these domains, further contributing to the economy. Indeed, there is a strong belief amongst the nation’s leaders and visionaries that 5G will be the catalyst in pushing India to become a $1 trillion economy by 2025.
