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 network. In such a situation, it can be very interesting to know that what is this upcoming 5G?
What is the technology used in it and how can it bring change in present 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 1980s, Second Generation (2G) in 1990s, Third Generation (3G) in 2000s, Fourth Generation (4G) in 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 5G network and when will 5G come in India?
What is 5G?
5G is the fifth generation of mobile networks. The full form of 5g is Fifth Generation. This fifth-generation wireless, or 5G, is the very latest cellular technology, which has been specially engineered to easily increase the speed and responsiveness of wireless networks.
Whereas in 5G, 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 5G, a large amount of data can be transmitted through wireless.
Here, apart from the improvement in speed, capacity and latency, 5G 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 5G 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.
5G 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 lot of variety of new applications through 5G.
Features of 5G Technology
Right now we know about some special 5G technology features. Let us know that what are the new features in 5G technology which are not in network technology.
- Up to 10Gbps data rate should be there. With this, there should be network improvement in 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 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 which 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 lower battery
- It provides better connectivity if you talk about any geographic region.
- It can support more number of supporting devices
- It takes very less cost to do infrastructural development
- Its communications have more reliability
How 5G 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 5G.
Where 4G requires large, high-power cell towers to radiate signals over longer distances, transmitting 5G 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 5G 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 lower-frequency spectrum in 5G networks so that network operators can use the spectrum that they already have. It is Mehjood.
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.
Main Challenges of 5G
Challenges are a big part of any new development. Because having these challenges can make 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 5G be viable?
Will some developed countries and developing countries also benefit through this technology?
To understand these questions better, the challenges of 5G have been divided into two headings –
1. Technological Challenges
2. Common Challenges
1. Inter-cell Interference – This is a very big technological issue which will have to be solved soon. Since there is a big 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 reqirement 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 is radio access network (RAN) challenges, which can later lead to overload and congestion.
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-eccentric, and data-rich wireless services that too on a standard basis.
2. Infrastructure – Due to the lack of infrastructure, the researchers have to face the inconvenience like many technological challenges of standardization and lack of application of 5G services.
3. Communication, Navigation, & Sensing – These services depend more on the availability of radio spectrum, through which signals are transmitted.
Since 5G technology has strong computational power to process large volume of data which comes from different and distinct sources, but it requires huge infrastructure support.
4. Security and Privacy – This is a very important challenge that 5G should pay special attention to so that people’s personal data can be protected. 5G 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 5G technology. Therefore it is also very important to implement Cyberlaw properly.
