What is Inside 5G Technology?
Wireless technology has been the most talked and used technology in the world for many decades. In the past world has experienced various generations of these wireless technologies before 5G technology has hit the technology world.
1G: The first generation of wireless cellular technology. These are the analog telecommunications standards that were introduced in the 1980s
2G: The second-generation wireless technology that consisted of GSM and CDMA.
3G: The third-generation technology that also consisted of GSM and CDMA. However, the speed increased from kbps to Mbps and gave the concept of Mobile broadband and video steaming on mobiles
4G: The fourth-generation cellular technology introduced LTE and drastically increased the speed from a few Mbps to a few hundred Mbps.
Now we have 5G technology, the 5th generation of Wireless cellular technology. The world is talking about it and companies are finding 5G implementation nearly inevitable for their survival. So, let’s see what this 5G technology is and what we could expect from it.
What is 5G technology?
5G is the fifth-generation wireless technology for digital cellular networks that began wide deployment in 2019. 5G is basically planned to greatly increase the speed and responsiveness of wireless networks. With 5G, data transmitted over wireless broadband connections can travel at multigigabit speeds and offer low latency of 1 millisecond or lower for real-time feedback. The thing about 5G that makes it so different from previous generations is that it can serve many devices at the same time with higher bandwidths and lower latency.
How do 5G works?
4G LTE (Long Term Evaluation) serves the foundation for 5G. Like other cellular networks, 5 G network is composed of cell sites that divide the area into sectors to send the radio waves. Each cell site is connected to the network backbone. The type of encoding used in 5G is similar to 4G LTE called OFDM (Orthogonal frequency-division multiplexing). Due to this more efficient encoding, 5G can get 30 times better speed than 4G. In the previous 4 Generation large, high power towers to radiate signals over large distances were used but 5G requires small cell stations to transfer its signals. The reason behind using small cells is that the band spectrum between 30 GHz and 300 GHz can only travel over short distances because they are subject to hindrance by Buildings, trees, and other obstacles. Lower frequency spectrum like that of 4G travels greater distances but has lower speed and capacity than MM waves used by 5G.
Features of 5G technology
Main features that make 5G distinct and more efficient from previous generations are:
- It provides high data rates that can also provide other new technology options on 5G networks like 4K streaming or VR etc.
- 5G will accelerate the service delivery at lower cost
- Unite Wireline, Wireless and Satellites services under one common structure
- Estimated 10 Gbps broadband speeds with peaks of 20Gbps with lower latency
- Small cell stations of 5G will give full coverage by making every home router a cell site.
Practical applications of 5G in daily life
- Driverless cars are much in talk nowadays but they will only come into action by the implementation of 5G. These cars will be self-contained and will provide more safety and efficiency.
- The prominent change 5G will bring is in Virtual and augmented reality. Phones are now transforming into devices that can be used with VR headsets. So lower latency provided by 5G can perform wonders in this domain.
- Downloading, browsing and live streaming speed will incredibly increase on the phones
- House to house fiber-optic lines can also be replaced by 5G home internet. In this process, carriers will only be required to install fiber optics to a cell site and provide customers wireless modems.
- 5G provides with the high-resolution wireless surveillance cameras and make devices more connected.
Difference between 4G and 5G
The key differences between 4G and 5G are that 5G provides a lower latency rate than 4G hence providing more real-time access. 5G is much faster than 4G with the speed up to 100 gigabits per second. 5G provides better bandwidth than 4G as 4Gand 3G are now facing bandwidth issues due to lack of infrastructure for current devices and new technologies.5G has better traffic capacity and uses spectrum better than 4G. 5G is capable of handling mission-critical communications and emerging IoT environments.
Things required to used 5G technology
It may seem very appealing to get 5G, however, it is not that simple as to use 5G technology first you require to have 5G enabled device. Right now there are not many 5G enables devices available in the market and the devices available are of premium level with high price value. After getting a 5G enabled device, the next you require is a 5G enabled networks. Right now no network is commercially providing 5G services and the things are in the testing phase. Proper spectrum allotment and cell stations need to be installed before 5G technology can be implemented in full swing.
5G Enabled Devices
5G cannot be obtained just via software update instead it requires specific hardware as discussed above. To use 5G services, a user must be having a 5G enabled device, a network that supports 5G and in the specific area where a 5G node is present. Some of the 5G enabled devices available in the market are:
- Huawei Mate X
- Huawei Mate 30 Pro 5G
- Xiaomi Mi MIX 3 5G
- Samsung Galaxy S10 5G
- Samsung Galaxy A90 5G
- One Plus 7 Pro 5G
Future of 5G
Right now many networks and countries are testing 5G technology and have attained incredible success. China and America are definitely in a race to introduce 5G commercially. They also faced some feud over the 5g concerns in the last few years however, they are ready to deploy 5G networks and services over the next several years to accommodate the increasing reliance on mobile and internet-enabled devices. In the future, 5G is expected to generate a variety of new applications, uses and business cases as the technology is rolled out.
