Real 5G Explained

Detailed 5G Tech Explanation

5G has been on everyone’s lips since 2018. But we bet only a few people know what 5G is all about. If asking an average user, they will say it’s the faster variant of 4G. And though there is a gain of truth, 5G technology is more than you think. In this article, we will try to introduce to you all the highlights of this technology.

Let's start from the beginning(1G-5G)

1G: This refers to the first generation of wireless telephone technology, namely mobile communications. It uses analog signals and has a speed of up to 2.4kbps. Phone with no screen could make calls.



2G(GPRS): This refers to the second-generation mobile technology. It uses digital telecommunications standards. The data rate is between 56-114kbps. 2G realizes the digitization of voice communication, and feature phones can send text messages with a small screen.



<3G(WCDMA/CDMA 2000/TD-SCDMA): Refers to the third-generation mobile communication technology. It provides a data rate of 384kbps. So you can easily browse websites and stream music.



4G: This refers to the fourth generation of mobile technology, known as LTE (Long Term Evolution). Compared to 1G-3G, it is the best among these types. And it is stable and fast like Wi-Fi at home or office.



5G is the fifth-generation mobile communication technology and an extension of the 4G system. On June 13, 2018, the San Diego 3GPP meeting set the first international 5G standard. Compared with the former, 5G networks have three main characteristics – extremely high speed (eMBB), extremely large capacity (mMTC), and extremely low latency (URLLC

The Need For High Speed

Communication relies on electromagnetic waves. And the frequency resources of electromagnetic waves are very limited. Different frequencies have different speeds. Frequency resources are like cars. The higher the frequency and the more cars, the more information can be loaded at the same time. Therefore, the greater the frequency, the greater the bandwidth, and the faster the speed. Currently, we use low-frequency bands for 4G. Its advantages are good performance and wide coverage, which can effectively reduce the operator’s investment in base stations and save money. But the disadvantage is that if there are more people, the ‘road’ of data transmission will be narrow. Although the existing technology has been optimized, the rate is still limited. While 5G uses high-frequency bands, the use of high frequency can not only relieve the tension of low-frequency resources but because there is no congestion phenomenon, the ‘roads’ are wider and the bandwidth rate is increased.
5G provides a peak data download rate of up to 10Gbps. The peak rate of 4G is about 100Mbps, and the speed is increased by 100 times. Ideally, users can download a 1GB HD video in seconds. 4K video requires a minimum download speed of 25Mbps. 4G cannot meet this requirement. Therefore, 4K live video broadcasting is possible under 5G environment. In addition, the demand for bandwidth in VR/AR is huge. And 5G is possible for the realization of virtualization such as VR.

Final Words

4G has achieved a significant increase in data rate, entered the era of mobile broadband, and changed people’s lifestyles. Whether it’s ordering, takeout, payment, etc., all have been changed by the mobile terminal. Thus, 4G changes lives, and 5G will change the whole society. It will give people a brand new media experience from virtual items such as VR/AR, virtual characters, and enhanced scenario information. It will also enter the era of the Internet of Things and penetrate into all walks of life -Internet of Vehicles, intelligent manufacturing, global logistics tracking system, intelligent agriculture, you get the point.
