Masroor Alam

Many questions must be coming to your mind like, how 7g technology works, when will 7g mobile come and when will 7G come in India. You will get all information today in this post.

Do you know what is 7G? How does this 7g technology work? In what ways is 7g better than 4G 5g, 6g? If you want to know about all these things, then you must read this post. Our relationship with phones is very old and equally strong.

Where earlier phones used to be wired, then came the era of cordless, and now wireless phones are running. Instead of the earlier basic phones, the people of today's generation use Smart Phones. With this changing appearance of the phone, its generation is also associated, which has decided the journey from 1G to 4G and is now moving towards 5G. In such a situation, it can be very interesting to know that what is this upcoming 5G?

What is the technology used in this and how can it bring a change in the recent Mobile Industry. How can people be obliged by this, etc?

If we look at the last few years, then we will be able to know that every 10 years there is an increase of one generation in the field of Mobile Technology. As we started First Generation (1G) in the 1980s, Second Generation (2G) in the 1990s, Third Generation (3G) in the 2000s, Fourth Generation (4G) in the 2010s, and now Fifth Generation (5G)...

We are slowly turning towards more sophisticated and smarter technology to hire. So today I thought why you should not be provided complete information about what is 5G and how it works so that you also know about this new technology. So without delay let's start and know what is 7g network is and when will 7g come to India?

What is 7g?

7g is the seventh generation of mobile networks. The full form of 7g is seventh Generation. This seventh-generation wireless, or 7G, is the very latest cellular technology, which has been specially engineered to easily increase the speed and responsiveness of wireless networks.
What is 7g

7g is the seventh generation of mobile networks. which has been specially engineered to easily increase the speed and responsiveness of wireless networks.

Whereas in 7g, data can be transmitted through wireless broadband connections at a speed of more than about 20 Gbps. Along with this, it offers very low latency which is 1 ms, and even less where real-time feedback is required. Due to the high bandwidth and advanced antenna technology in 7g, a large amount of data can be transmitted through wireless.

Here, apart from the improvement in speed, capacity, and latency, 7g also provides other network management features, the main one being network slicing, which allows other mobile operators to create multiple virtual networks, that too a single physical network. in 7g network.

With this capability, wireless network connections can be used in specific uses or business cases and can also be sold on an as-a-service basis. For example, a self-driving car, which requires a network slice that provides extremely fast, low-latency connections. With this, a vehicle can navigate in real-time.

A home appliance, on the other hand, can be connected via a lower-power, slower connection because it doesn't require high performance. Apart from this, in the internet of things (IoT), we can use secure, data-only connections.

7g networks and services will be deployed in several stages over the next few years to meet the needs of growing mobile and internet-enabled devices. Overall, we can generate a variety of new applications through 7g.

4G is currently expanding in India, but telecom operators around the world are preparing to bring 7g the next generation of mobile technology. That is why he has started preparing to bring 5G.

Features of 7G Technology

Right now we know about some special 7g technology features. Let us know that what are the new features in 7g technology, Up to 10Gbps data rate should be there. With this, there should be network improvement at the rate of 10 to 100x as compared to 4G and 4.5G networks.

  • Having 1-millisecond latency
  • 1000x bandwidth per unit area
  • In this, we can connect up to 100x number of connected devices per unit area (if we compare with 4G LTE)
  • It is available all the time. Hence its availability is up to 99.999%
  • Apart from this, it provides 100% coverage.
  • It helps a lot in saving energy. Due to which it helps in reducing network energy usage by almost 90%.
  • In this, you can use low-power IoT devices that can provide you power for about 10 years.
  • It has a high increased peak bit rate
  • Higher data volume per unit area (i.e. higher system spectral efficiency)
  • Has more capacity which helps it to be connected concurrently and instantaneously with more devices
  • It consumes a lower battery
  • It provides better connectivity if you talk about any geographic region.
  • It can support more number of supporting devices
  • It takes very little cost to do infrastructural development
  • Its communications have more reliability

How 7G Technology Works

Wireless networks mainly consist of cell sites which are divided into sectors that send data through radio waves. It would not be wrong to say that the fourth-generation (4G) Long-Term Evolution (LTE) wireless technology was the foundation of 7g.

Where 4G requires large, high-power cell towers to radiate signals over longer distances, transmitting 7g wireless signals requires many smaller cell stations, which are located in small spaces such as Can be installed in light poles or building roofs.

Here multiple small cells are used because it is in the millimeter-wave spectrum — the band of spectrum is always within 30 GHz to 300 GHz and since 7g needs to generate high speeds, which are only short distances. can travel.

Apart from this, these signals can be easily interfered with by any weather and physical obstacles, such as buildings.

If we talk about the wireless technology of the first generation, then the lower-frequency bands of the spectrum were used in it. Along with this, the wireless industry has thought of using a lower-frequency spectrum in 7g networks so that network operators can use the spectrum that they already have.

One thing we should keep in mind is that the lower-frequency spectrum always covers more distances but has lower speed and capacity than the millimeter-wave.

What is the status of the 7g deployment?

The main development of 7g is the highest among these four countries of the world, they are the United States, Japan, South Korea, and China. Here wireless network operators are paying more attention to making 7g. It is believed that network operators are going to spend about crores of billions of dollars in respect of 7g by 2030.

Well-known tech company Technology Business Research Inc., says that it is still not clear how these 7g services will generate a return on their investment.

It is expected that new companies and startups who want to use 7g Evolving technology can take care of the revenue of these operators.

Simultaneously, other standards bodies are also operating on top of universal 7g equipment standards. Nearby, the 3rd Generation Partnership Project (3GPP) has approved 7g New Radio (NR) standards in December 2017 and by the end of 2018, the 7g mobile core standard that is essential for 7g cellular services will end. expect to pay. 

This 7g radio system is not compatible with 7g radios, but network operators have purchased wireless radios that they want to upgrade. They want to upgrade it through software and not hardware update because they may need to buy new equipment in hardware update.

The first 5G-compliant smartphones and other associated wireless devices are expected to be commercially available by 2019, while the 5G wireless equipment standards have almost expired. Full use of 5G technology is expected from 2020. By 2030, 5G services will be used in a full-fledged form and will be used in autonomous vehicle navigation in virtual reality (VR) content. It can also be monitored in real-time.

Types of 7g wireless services

Network operators mainly provide two types of 7g services. The first service is 7g fixed wireless broadband services that deliver internet access to homes and businesses without any wired connection to their premises.

To do this, network operators deploy NRs in small cell sites near buildings so that they can beam a signal to a receiver that is located on a rooftop or windowsill, thereby amplifying it within the premises.

Fixed broadband services also become cheaper for operators to provide service as through this approach they do not need to lay fiber-optic lines to each residence, but have to install fiber optics only to cell sites, and customers broadband services are received through wireless modems located in their residences or businesses.

The second service is 7g cellular services, which allows the user to access the operator's 7g cellular network service. These services will be first rolled out in 2019 when the first 5G-enabled devices will be commercially available for purchase.

The delivery of cellular service also depends on the completion of mobile core standards through 3GPP. It is expected that it will be completed by the end of 2018.

What are the Advanced Features of 7G?

If we compare this new 5G technology with the earlier radio technologies, then we can see this following advancement in it such as –

  • In this, we can get practically super speed which is 1 to 10 Gbps.
  • Latency here will be 1 millisecond (in end-to-end round trip).
  • With this there is 1,000x bandwidth per unit area.
  • It can easily connect up to 10 to 100 devices.
  • It provides Worldwide coverage.
  • Apart from this, it has a hand in the energy reduction of about 90%.
  • Battery life is very long in this as compared to others.
  • With this, the whole world becomes a wifi zone here.

What is the spectrum band of 7G

7g networks run on the 3400 MHz, 3500 MHz, and 3600 MHz bands. The 3500 MHz bands are considered ideal. Millimeter-wave spectrum can play an important role in 7g. They are called millimeter waves because they have a length of 1 to 10 mm.

Millimeter waves operate at frequencies from 30 to 300 GHz. So far these waves can be used in satellite networks and radar systems.

If millimeter waves are used in 7g, then the credit will also go to Sir Jagdish Chandra Bose. He showed in 1895 that these waves could be used for communication.

What are the main advantages of 7g?

By the way, there are many advantages of 7g, so I have tried to tell you about them below –
  • Having high resolution and bi-directional large bandwidth parameters.

What are the Main Dis-Advantages of 7g?

7g technology is designed in a very researched and conceptualized way to eliminate all the radio signal problems and hardships of the mobile world, but still, it has some disadvantages which we are going to discuss further.

  • This 7g technology is still under process and research is going on behind it.
  • The speed which it is talking about providing, it seems difficult to achieve because so far that much technological support for it is not present in many parts of the world.
  • Many old devices are not compatible with this new 7g technology, due to which they will have to be replaced, which will prove to be an expensive deal.
  • It may cost more to develop its infrastructures.
  • There are still many security and privacy-related issues in this which are yet to be solved.

Main Challenges of 7G

Challenges are a big part of any new development. Because having these challenges can make the technology even better. Like all technology, there are many big challenges in 5G too. We have seen in the last few years how radio technology has made rapid growth.

Starting from 1G to 5G, this journey is only for 40 years (1G in the 1980s and 5G which is to come in the year 2020). But in this journey, we have also observed some common challenges such as lack of infrastructure, research methodology, and cost.

In today's world, there are many such countries where 2G and 3G technologies are still used and people still do not know about 4G there, in such a condition, the question which is in everyone's mind is that -

How far will this 7G be viable?

Will some developed countries and developing countries also benefit from this technology?
To understand these questions better, the challenges of 7G have been divided into two headings –

1. Technological Challenges 
2. Common Challenges

Technological Challenges

1. Inter-cell Interference – This is a very big technical issue that will have to be solved soon. Since there is a huge difference in the size of traditional macro cells and concurrent small cells, it can cause interference in the future.

2. Efficient Medium Access Control – In situations where there is a dense deployment of access points and requirements of user terminals, user throughput will be low, latency will be high, and hotspots will not be capable of providing high throughput with cellular technology. For. Therefore it is necessary to research it properly to optimize this technology.

3. Traffic Management – ​​Cellular networks having more human traffic and having more number of Machine to Machine (M2M) devices in the same cell can create serious system challenges which are radio access network (RAN) challenges, which can later lead to overload and congestion.

Common Challenges

1. Multiple Services – Compared to other radio signal services, 5G has to perform larger tasks such as operating heterogeneous networks, technologies, and devices that work in different geographic regions. Therefore, the challenge is that people have to provide dynamic, universal, user-centric, and data-rich wireless services that too on a standard basis.

2. Infrastructure – Due to lack of infrastructure, researchers have to face inconveniences like many technological challenges of standardization and lack of application of 7G services.

3. Communication, Navigation, & Sensing – These services depend more on the availability of radio spectrum, through which signals are transmitted.

Since 7gtechnology has the strong computational power to process large volumes of data that come from different and distinct sources, but it requires huge infrastructure support.

4. Security and Privacy – This is a very important challenge that 7g should pay special attention to so that people's personal data can be protected. 7g will also have to pay special attention to many other security threats such as trust, privacy, cybersecurity because these threats are increasing continuously all over the world.

5. Legislation of Cyberlaw – Cybercrime and other frauds will also increase due to the presence of high speed and ubiquitous 7g technology. Therefore it is also very important to implement Cyberlaw properly.

When will 7G come to India?

You must be wondering when will the 7g mobile be launched? The government has started preparations for the auction for the 7g spectrum. The government has asked TRAI to suggest starting prices for the auction of 3400 to 3600 MHz bands. TRAI has started work on it. The Department of Telecom may soon bring a policy in this regard.

In fact, experts believe that regulatory conditions for data hosting and cloud services should be changed before bringing fast wireless technology like 7g to India.

Future Scope of 7g?

A lot of researches and discussions are going on all over the world among world-famous technologists, researchers, academicians, vendors, operators, and governments regarding innovations, implementation, viability, and security concerns 7g.

As it has been said that there are many such features in 5G which will provide the best services. But a question that must be in everyone's mind is that where the previous technologies (4G and 3G) are still under process and in many parts have not started yet; So what is the future of 7g?

7th generation technology has been specially designed so that it can do incredible and remarkable data capabilities, unhindered call volumes, and immeasurable data broadcast through this latest mobile operating system.

Therefore it is more intelligent technology, which will prove helpful in interconnecting the whole world. Similarly, our world will get universal and uninterrupted access to information, communication, and entertainment, so that it will open the door of a new dimension in our lives and it will make our lifestyle better and meaningful.

Along with this, governments and regulators will also be able to use this technology to create better governance and healthier environments. One thing is clear from this that the right attitude of the people in the expansion of 5G will be helpful in making it even better.
