what is 5G

It is the 21st century, and we live in a world surrounded by technology. Cellular networks have evolved. The last few decades have had some incredible results. The world is now eying on to the next level of higher network speeds and accessibility to the consumer. The networks changed from 1G,2G,3G,4G, and the marvellous 5G technology. 

5G technology is leading the world in new directions. The future generations will have a much more advanced lifestyle. This technology will serve humanity in several ways. So, the epicentre of our discussion will be revolving around 5G.

In this article, you will get to know all the fundamental thoughts coming to a person’s mind. What is 5G, who invented 5G, how does it work, and the advantages and disadvantages of the 5G technology? We will be going through a complete set of guidance related to this fascinating technology.

What is 5G?

5G is the fifth-generation wireless technology characterized by higher bandwidth, incredible speed, and lower latency. The 5G technology is far better in speed and connectivity than the 1G,2G,3G, and 4G networks. 

5G is a successor to the 4G network, making it the fastest network to date. The 5G network can transform the user experiences to the next level. 

The promising feature of the 5G technology includes:

  • Higher Gbps peak data speeds.
  • Low latency.
  • More accessibility and reliability.
  • A user-friendly experience.

Who Invented 5G?

Nobody in person has developed the 5G technology. Various companies on the network and run the network to more practical use. In addition, South Korea is the first country to launch the 5G technology, and the estimates suggest that almost 60 percent of the population will benefit from 5G by 2025.

Several multinational companies are working on the 5G networks in different parts of the world. In the United States, companies like Verizon, AT&T, and T- Mobile own the role of frequency broadcasting of 5G.

While in China, the network is owned by the state, but some companies share the 5G technology, including Ericsson, China Telecom, and China Unicom.

The leading companies that facilitate the 5G technology all across the globe include Qualcomm, Ericsson, Huawei, Nokia, Samsung, ZTE, and a few more.

How Does 5G Work?

The working of the 5G network does not involve any complexity to understand. The network works using the radio frequencies by the wireless communications systems through the air. The network integrates 4G with 5G, which provides faster speed as two servers are used. 

The 5G technology uses a band of frequency known as SUB 6 ( 600 MHz-6GHz); apart, they can range up to a larger 24 GHz as much higher 86 GHz band frequencies. As a rule, the higher the frequency, the more data rates, and much better performance.

The 5G network uses “small cells,” a version of the cellular tower; these cells will eventually work on beamforming, evenly distributing the data network. The data travels through in higher bands known as “millimeter waves” (mm waves).

5G technology can be interrupted by physical barriers such as buildings and other objects, so to cope with this problem, multiple antennae networks will increase the signal transmission. Some transmitters can help in the smooth flow of the signals in the wireless network.

The slice network concept will come to play for a better user experience. Each activity will have a separate virtual network that will provide much more manageable and better accessibility.

How Fast Is 5G Than 4G And 3G?

5G is 100 times faster than 4G, 5G as it is expected to have data speeds of 10 Gbps. It will be faster than 3G and 4G collectively. The average download speed of 200Mbps compared to the 3G, which has 8Mbps, 4G has 32.5Mbps, and 4G LTE has a download speed of 42Mbps. 

In general, this whole data reflects that a full HD movie will take 4 hours on a 3G network, 10 minutes on a 4G network, and 20-30 seconds on 5G.

Worldwide Accessibility

5G is thought to be the predecessor of the 4G network. It was first launched in 2019 in South Korea. According to the GSM Association, the 5G will reach up to 1.7 billion subscribers worldwide.

America and Europe are upfront in implementing 5G, followed by Asian countries. There are 58 countries with 5G technology as of 2021. 5G is widely available in South Korea, Saudi Arabia, Kuwait, Hong Kong, and the USA.

According to Statista, cities with the fastest 5G speeds include Jeonju (South Korea), Hsinchu City (Taiwan), Riyadh (KSA), Dubai (UAE), and Tokyo (Japan).

Which Phone Does Support 5G?

If you want to use the 5G technology, it wouldn’t be possible with the current smartphones. The 5G technology is only possible on the modern 5G smartphones. The mobile phone giant companies like Huawei, Samsung, Apple are introducing new smartphones compatible with the 5G network.

What are The Advantages Of 5G

  • Safer Vehicles cars will communicate within a fraction of a millisecond.
  • Faster Data Transfer, the data from one device to another, will be ten times faster than 4G.
  • Reduces website waiting time to 1ms or less.
  • Decreases the app load time by 1-2 seconds.
  • It makes IoT devices’ battery life last ten times longer.
  • Remote surgery could be possible.

What Are The Disadvantages Of 5G

  • It could be expensive in case to buy new gadgets for 5G
  • 5G infrastructure needs much money to replace the existing network.
  • It can create health problems due to the radiation.
  • Privacy and security issues are a concern.


The 5G technology is something that will help the future generation in various fields. The advancement in the technology field aided by 5G is a significant feat in history. 5G will assist the business, hardware, and health sector.

5G will transform the work experiences as the world is already shifting to work from home. People will also benefit from AI and the Internet of Things (IoT) because of 5G. 5G will reduce the number of car accidents.

Although it has many positives, it has some concerns such as the harmful radiation, privacy might be affected, and being used to be a tool against other countries.
