What is 5G Technology? How it Works, Strengths and Weaknesses

This fifth-generation cellular wireless network was first declared in the country with the most rapid technological advances, namely South Korea.

Even so, the development of this 5G network has been started since 2008. The inventor of this 5G network is Michael Lemke. The inventor of 5G was researched at the University of Technology. This 5G network is expected to help human tasks and also make it easier for users to surf online.

Moreover, this interesting fact about the 5G network can be used for other advanced technology devices such as smart cars where the car can run on its own with the help of the 5G network. Well, for more details about the 5G network, let's immediately see the following article!

What is 5G Network Technology?

5G Network Technology

5G is one of the broadband cellular network technologies that enters the fifth generation. This network technology is certain to be the successor of 4G network technology which is currently being used in various countries including India.

However, only a few points can be used and also some smartphones that support 5G itself, including:

• Samsung Galaxy S21
• iPhone Series 12
• Oppo Reno5
• Xiaomi Mi 10T
• Huawei Mate 40 Pro, etc.

There are still many other best smartphones that have started to launch with 5G support.

For cities and other providers, it seems that it will follow, considering that many internet users are already waiting for the presence of this 5G network technology.

5G network technology certainly has more advantages compared to previous networks because this network has greater bandwidth, lower latency and faster download speeds.

That way, you can stream YouTube without buffering , downloading large movies only takes a few seconds, and this technology already supports Augmented Reality (AR).

its, not only that! 5G technology is also one of the software platforms whose network is managed through software rather than hardware.

This technology will also enhance digital experiences that have been automated using machine learning, artificial intelligence so that cars that support Self Driving and other advanced technologies can be used.

History of 5G Network Development

Although this 5G network technology is the next generation, of course behind its sophistication there is a history of previous network technology developments. Starting from 1G, 2G, 3G and 4G LTE networks.

Every generation goes through a process of development. Well, for the history of the development of network technology, you can see the following:

1. First Generation – 1G

First Generation – 1G

This first generation network was launched in 1971 by Nippon Telegraph and Telephone in Tokyo. 1G network has no security because there is no encryption, even the download speed is only about 2.4Kbps.

2. Second Generation – 2G

Second Generation – 2G

Furthermore, for the second generation, it was first launched globally in 1991. This 2G network is also known as cellular communication (GSM).

Unlike the previous generation, on this network there has been an increase in voice quality and download speed which is already 0.2Mbps.

On this 2G network, users can send or transfer data from one phone to another using SMS and MMS to send pictures, audio, video. If you've ever used an old-school phone, you've definitely experienced sending MMS!

3. Third Generation – 3G

Third Generation – 3G

Next is the third generation network, namely 3G. This 3G network was first launched in 2001 in Japan by NTT Docomo. This network is certainly experiencing development when compared to the previous 2G network.

On 3G networks, users can transfer data 4 times faster with an average delivery rate of 2Mbps. Even on this network, users can make video calls using video calling applications such as Skype.

In addition, for the 3G network users can also stream video, send email using a cell phone. Let's admit it.. who has experienced this 3G network before?

4. Fourth Generation – 4G LTE

Fourth Generation – 4G LTE

Furthermore, the fourth generation is 4G or also known as LTE. This network was first introduced in 2009 in Norway. On this network, users can experience sending data transfers at only 12.5Mbps.

On this network users can stream high quality videos, surf the internet using the best web browsers quickly, play online games and so on.

5. Fifth Generation – 5G

Fifth Generation – 5G

Finally, the fifth generation network is 5G. The network was first launched in 2019 in South Korea. This network was created as the latest development of the previous network.

Many even suspect that the 5G network can be 20 times faster than the 4G network. Because there is a significant difference. The 5G network itself already has higher latency and bandwidth than 4G.

Even the lowest latency on 5G networks is 1 millisecond. So it won't be surprising if later the download and upload speeds will feel faster and also the quota will run out faster.

For the size of the 5G network bandwidth itself, it can even reach between 30GHz and 300GHz! This size will certainly support many future advanced technologies , such as smart homes and smart cars.

How the 5G Network Works

How the 5G Network Works

Surely you are also wondering, how does the 5G network work? Yup, this 5G network has a way of working that is not much different from the previous network. So this 5G network will transmit data via radio waves.

The radio waves will later be divided into several different frequencies and each type of frequency will also have a different type of communication.

Examples include signals for television broadcasts, navigation signals for maritime and mobile data signals. The 5G network itself is a type of coding from Orthogonal Frequency Division Multiplexing (OFDM).

The encoding is indeed similar to the previous network encoding, namely 4G LTE. Although similar, the 5G network has been designed to use lower latency and also greater flexibility compared to LTE.

Advantages of 5G Network

With this 5G network technology, it will certainly provide some useful impacts because of its advantages. So, here are some of the advantages of the 5G network:

1. Lower Latency Rate

Lower Latency Rate

The first advantage is that 5G networks have lower latency than 4G LTE networks. So that when transmitting data, it only takes less than 5 milliseconds.

It can even be up to 1 millisecond. That way, the 5G network can be used by users to control the network remotely in real time.

Weaknesses of 5G Network Technology

If there are advantages, there are disadvantages. Well, here are some of the weaknesses of 5G network technology:

1. Quota runs out fast

Quota runs out fast

With the fast internet speed of 5G, of course, it will consume a lot of quota. So that later you will feel the price of a more expensive data package and will save your quota more often!

5. Different Upload and Download Speeds

Different Upload and Download Speeds

Finally, because the download speed of this 5G network will certainly not be balanced with the upload speed. Moreover, some rumors say that this 5G network upload speed is often more than 100Mbps!
