5G is the next generation internet network of cellular internet network technology after 4G. Just like every previous generation, 5G aims to make cellular communication faster and more reliable as more and more devices are online. And this is stated as internet technology with 10X speed faster than 4G.

5G internet network technology

Unlike in the past, when cellular internet networks only needed to support cell phones that were only used to surf the web and text messages, now almost all types of devices require internet with large bandwidth capacity such as smartphones for streaming HD video, smart watches with data packages , and security cameras that are always active, self-driving and cars connected to the internet, and other promising devices such as health sensors and increasingly evolving AR and VR devices.

As many devices are connected to the web, the entire infrastructure needs to accommodate traffic to not only support faster connections but also better deal simultaneously and provide broader coverage for these devices. And here’s a complete explanation of 5G wireless internet.

1G 5G internet network technology revolution

5G is just the next number generation after 4G, which replaces all the old technology.

  • 1G introduces analog sound
  • 2G introduces digital sound: 2G signifies second generation wireless digital technology. The fully digital 2G network replaced the analog 1G technology from the 1980s. 2G network as the first commercial network on the GSM standard. GSM, which allows international roaming, is an acronym for global systems for cellular communication.
  • 3G delivering cellular data: 3G services, known as third generation services, are high-speed access to data and voice services, which are made possible by the use of 3G networks. The 3G network is a high-speed cellular broadband network, offering a minimum data rate of 144 kilobits per second (Kbps).
  • 4G paves the way for wider use of cellular internet: 4G Wireless is a term used to describe fourth generation wireless cellular services. 4G is a big step up from 3G services and up to 10 times faster than 3G services. Sprint was the first operator to offer 4G speeds in the United States starting in 2009. Now all operators offer 4G services in most areas of the country including Indonesia, although some rural areas only have slower 3G coverage.


The timing of the launch of 5G internet technology depends not only on where we live but also which service providers are available in our area.

At present, 5G is only available in several locations in certain countries, so not just anyone can register for this service for a while and of course in Indonesia it is also not yet available. Verizon, AT&T, Sprint, T-Mobile, and several smaller companies already provide 5G for customers in the United States, but especially in big cities. There are also several other operators that have 5G networks already in other places around the world.

5G phones are also an important component of this new fifth generation cellular network because not just any telephone can work with 5G networks. Mobile phones and other devices running on the 5G network are available from several providers and in some developed countries will come out later this year.


Internet service providers, cellular network operators, and other companies are constantly coming out with trials of new 5G internet technology and other announcements when 5G is launched worldwide.

  • September 24: Xiaomi announces the Mi 9 Pro 5G smartphone.
  • 24 September: Nokia opens 5G Future X Lab at its headquarters in Finland.


This may seem obvious considering that today almost everyone uses smartphones everywhere, but even though mobile phones are clearly a major player in this cellular communication, 5G is clearly not the only focus in the 5G network for cellular.

As you will see below, components that use 5G will have ultra-fast connections and very minimal pauses. Anyone who is streaming video from their smartphone, will be really very fast and there is no pause like the network we use today.

One application that will use 5G is of course the Augmented Reality device and the Virtual Reality headset. This device requires an extraordinary amount of bandwidth and needs to communicate via the internet as fast as possible to provide the desired effect. Any latency can drastically affect the “real” feeling in the virtual environment.

The same is true for other devices that need to respond quickly, such as autonomous cars to avoid sudden collisions and understand correct turn-by-turn directions, hardware that is operated remotely, and robotic systems that study or adhere to remote controls.

In addition, 5G still paves the way for smoother connectivity from our everyday devices, too, such as when playing games, making video calls, streaming movies, downloading files, sharing HD and 4K media, receiving real-time traffic updates, vlogging , etc.

5G is so fast that it’s not only available for mobile devices. This has the potential to completely replace your high-speed cable connection via fixed wireless access!

Like other wireless communication methods, 5G internet sends and receives data in the radio spectrum. However, unlike what we use with 4G, 5G uses higher frequencies (millimeter waves) in the radio spectrum to reach ultra fast speeds.

The disadvantage of using high frequencies to transmit data is that these frequencies experience more interference from things like trees and buildings, which means that strategically positioned small towers are needed to drive networks throughout the city.

However, not all cellular network operators work the same way. Some companies use the 5G internet network at the lower end of the radio spectrum so that the transmitter tower can reach a wider area and penetrate walls, but the exchange is slower speed.


With 5G internet technology, everything related to cellular communication is faster, starting from the speed at which you can download and upload data to a number of devices that can be connected to the internet simultaneously.

Cell 5G, which sends and receives cellular data, supports speeds of at least 20 Gb / sec for downloads and 10 Gb / sec for uploads, with latency as low as 4 ms or more.

However, in most situations, this might translate to real world speeds of 100 Mb / s (12.5 MB / s) and 50 Mb / s (6.25 MB / s), respectively, but can easily fluctuate upward or down depending on various circumstances. In comparison, the average cellular download speed in the United States is around 30 Mbps – three times slower than that available on the 5G internet network.

For example, in an ideal situation with a speed of 5G as fast as 1 Gb / s, you can download 3GB movies to your cellphone in 24 seconds, or upload a 1GB YouTube video in just eight seconds.


At least 5G networks must support 1 million devices for every square kilometer (0.386 square miles). This means that in that amount of space, the 5G internet network is able to connect 1 million or more devices to the internet at the same time.

This type of scenario might seem difficult to understand given the cities with the highest population densities (such as Manila Philippines, Jakarta Indonesia and Mumbai India) “only” can accommodate between 70,000 and 110,000 people for every square mile.

However, 5G internet technology does not need to support only one or two devices per person, but also everyone’s smart watches, all vehicles in the area that may be connected to the internet, smart keys in nearby homes, wearables, and every stream or other newly-released devices that need to be on the internet.

It is estimated that, globally, there will be 1.3 billion connections on the 5G network by the end of 2023.

Cell 5G can communicate with all types of devices, such as those used by silent people who don’t move to someone in high-speed vehicles such as trains, who travel up to 500 km (310 mph).

It is possible that different areas will require different cellular base stations to accommodate different speeds. For example, a small city that only has users traveling by car and on foot might not have the same base station as a large city with a high-speed public transportation system.


5G and other cellular broadband standards are set by the 3rd Generation Partnership Project (3GPP). 3GPP Release 16 is the “phase 2” of the 5G project, and will be completed by March 2020.

For a much more technical reading of the 5G specification, see this Microsoft Word document released from the International Telecommunication Union (ITU).

After 5G is widely available, it is likely that it will be a big improvement nowadays in cellular internet networks. Instead of switching to 6G or 7G internet technology later, we might just stick with 5G technology but get a gradual improvement over time.

Very confusing when talking about 5G with 5 GHz Wi-Fi, but the two are not the same. The first is cellular network technology while the latter is the frequency band used in some Wi-Fi routers.


And that’s a complete explanation of the 5G internet network technology that will replace 4G in a few years later. Hopefully our country will also bring 5G in its network, but of course when 5G comes, smartphone devices and other devices have to adjust or we have to buy more new devices that support 5G to enjoy new technology faster.
