5G technology in India - Pros and Cons



. 6 min read


The Connected World is all about connecting people, devices, and systems to the Internet and exchanging and interacting with data across a wide range of industries, such as healthcare, manufacturing, transportation, energy, agriculture, smart cities, construction, infrastructure, and security. The Connected World is all about the Internet of Things (IoT), which is a network of interconnected computing devices and systems.

Exactly what does it mean to revolutionize with 5G?

The term "5G" refers to the fifth generation of cellular network technology. The advent of 5G, which can be up to 100 times faster than 4G, is presenting previously unimaginable opportunities to both customers and companies.

2019 marked the beginning of widespread deployment of the fifth-generation (5G) technology standard for broadband cellular networks, which cellular phone carriers are currently in the process of implementing. It is intended to take the place of existing 4G networks, which now connect the vast majority of mobile devices. The GSM Association and Statista predict that by the year 2025, 5G networks will have more than 1.7 billion subscribers and will account for 25% of the worldwide mobile technology sector.

The expansion of society, the revolutionization of various industries, and the major improvement of day-to-day experiences are all being facilitated by increasing bandwidth, ultra-low latency, and faster connectivity. E-health, connected autos and traffic systems, and advanced mobile cloud gaming were once regarded as examples of services that would not be possible in the foreseeable future but have now become a reality.

Important Gains to Be Obtained from the Emergence of 5G:

1. An increase in the rate of transmission: It is possible to achieve transmission speeds of 15 or 20 Gbps. Because of the rise in speed, we now have access to data, programmes, and remote applications in a manner that is totally immediate and does not require us to wait. Because computing can be done on the Cloud, all devices (mobile phones, computers, etc.) will rely less on their internal memory and the accumulation of data, and it will not be necessary to instal a significant number of processors on some items. In addition, data will be able to be accessed more quickly.

If you are able to remotely activate software as though it were running on personal devices, for example, you will be able to avoid installing mobile applications (APPs) on the terminal and instead run them directly from the cloud. This is because you will be able to remotely activate software as though it were running on personal devices. In a similar vein, it won't be necessary to save the information in the memory of the gadget any longer (photos, videos, etc).

2. Decrease the amount of time that passes between when an instruction is given on our device and when the action actually takes place. Latency refers to the amount of time that elapses between the two events. Because 5G's latency will be 10 times lower than that of 4G, it will be possible to carry out tasks at a faraway location in real time.

Controlling the machinery of an industrial plant, controlling logistics or remote transport, performing surgical operations in which the surgeon can intervene on a patient who is on the other side of the world using precision instrumentation managed remotely, or complete control of automated and driverless remote transport systems are all now possible thanks to the low latency and increased sensor density.

3. An increase in the number of devices that can be connected to the network: 5G enables a significant increase in the number of devices that can be attached to the network, reaching millionaire levels per square kilometer. Every device that is connected to the internet will have immediate access to the internet and will be able to communicate and share data with one another in real time.

4. Network slicing: 5G also enables the construction of virtual networks (network slicing) and the implementation of subnets in order to provide a connection that is more specifically customized to meet the requirements of individual users.

The development of subnetworks will endow a portion of the network with unique qualities, transforming it into a programmable network. Additionally, the creation of subnetworks will make it possible to prioritize certain connections, such as those related to emergencies, in front of other users. This can be accomplished by applying different latencies to these connections or prioritizing them within the network connection, ensuring that they are not impacted by any potential mobile network overloads.

The disadvantages of 5G include the fact that gigabit mobile communications have so far provided users with very little added value.

Because there is still an insufficient supply (particularly in rural regions), it is required to purchase new equipment.

When compared to 4G, 5G requires a greater number of transmission antennae to achieve uniform network coverage.

There is not yet a conclusive answer to the question of whether or not radiation from mobile devices poses a threat to human health.

Which nation was the first to implement 5G technology:

As of April 2019, the Global Mobile Suppliers Association had compiled a list of 224 operators in 88 countries that had demonstrated, were testing or trialling, or had been licensed to conduct field trials of 5G technology; were deploying 5G networks; or had announced service launches. These operators were either testing or trialling 5G technology; deploying 5G networks; or had shown interest in launching 5G services. As of the month of November in 2018, there were 192 operators spread throughout 81 nations.

In April of 2019, South Korea was the first country in the world to implement 5G on a widespread scale. The Swedish telecommunications company Ericsson forecasts that by the end of the year 2025, up to 65 percent of the world's population would have access to 5G internet. In addition to this, it plans to make an investment in Brazil up to one billion reals, which is equivalent to $238.30 million, in order to construct a new assembly line that will be dedicated to fifth-generation (5G) technology for its operations in Latin America.

Will my current SIM card be compatible with a gadget that supports 5G?

Your 5G device will, in fact, be able to use a 4G sim card in order to receive 4G/3G/2G coverage depending on your need. You will, however, need to replace your current sim card with a 5G sim card in order to connect to our 5G network.

Even though the first day of the initial launch of 5G services was October 1, 2022, only two of the three operators have started the first day of the initial launch of 5G services. On October 5, the 5G network that is being being tested by Reliance Jio went live for public use.

The 5G services of Bharti Airtel have been introduced in eight different places in India. Services known as "Airtel 5G Plus" are now accessible in a total of eight cities: Delhi, Mumbai, Chennai, Bengaluru, Hyderabad, Siliguri, and Nagpur. Varanasi is also included in this list. The company has announced that it plans to roll out its 5G network across the urban areas of India by the year 2023. Both Jio and Airtel 5G will be compatible with previously purchased SIM cards.

Due to the low levels of network stress that would exist during the debut phase of the 5G network, some sources claim that mobile subscribers could see download speeds of up to 600 megabits per second. However, after the whole rollout is complete, it will not change from the range of 200 to 300 MBPS. At a maximum download speed of 600 megabits per second, a two-hour high definition movie that has a file size of around 6 gigabytes may be downloaded in 1 minute and 25 seconds, while a 4K movie can be downloaded in approximately three minutes.

N3, N5, N28, N77, N78, and N258 are the 5G bands used by Jio in India. The 5G bands used by Airtel in India are N1, N3, N8, N77, and N258.

The 5G bands used by Vodafone are designated as N1, N3, N77, N78, and N258.


The purpose of the 5G wireless technology is to give an improved user experience that is more consistent across all users by offering multi-Gbps peak data rates, ultra-low latency, greater dependability, large network capacity, increased availability, and increased availability. Enhanced performance and efficiency make it possible to create new user experiences and connect previously unrelated sectors.
