What is 5G wireless technology applications?. In the cellular world, recently we have enjoyed 4G technology which is the development of 3G and 2G.
Over time, this technology will be replaced by the development from 4G to 5G (Fifth Generation).
5G technology itself is to be able to provide data transfer speeds of 10 to 100 times faster than 4G which will have a wider range and more stable connection.
5G networks can make better use of the radio spectrum and allow users to access the mobile internet simultaneously.
Tests conducted by the United States (US) showed that 5G technology can provide data transfer speeds of up to 1000 Mbps per second.
In other words, 5G technology is 25 times faster than 4G technology and can still potentially increase its speed up to Gbps.
About 5G Wireless Technology Applications
There are several new technologies that are possible to implement. But the standards that are own may not necessarily be able to meet all 5G protocols.
The frequency band contains in 5G technology allows it to be installed at a frequency of 3.5 GHz to 26 GHz or higher.
The frequencies used have various capacities but the wavelength is shorter so the range will be lower. Thus, the creation of new technologies makes it possible to apply.
For example, making the transmitter tower smaller and placed closer to the ground. This has the potential to transmit millimeter waves between a much higher number of transmitters to receivers.
When compare to 4G and LTE networks, 5G networks can be use in three different types of spectrum, namely low band, mid band, and high band. In the low band.
The coverage area is wide but has a weakness in the maximum data rate which only reaches 1000 Mbps.
Then for the mid band only reaches a maximum data rate of 1 Gbps. As for the type of high band spectrum. It is consider more suitable for 5G wireless technology applications.
Because it is able to transfer data at speeds up to 10 Gbps. However. The main problem is that the coverage area of the high band is not wide enough compared to other spectrums.
Although in fact the speed that is quite large, it is not the same as the actual speed. The download speed by the user will be estimate at only 100 Mbps with the upload speed only around 50 Mbps.
Internet of Things on 5G
Reported by The Sun, the Internet of Things (IoT) on 5G networks allows work to be complete very quickly.
IoT is an interrelated computing concept with the ability to transfer data over a network without requiring human-to-computer interaction.
This means, machines will exchange information and commands autonomously without any involvement with humans (automated systems).
Internet of Things (IoT) is useful in tracking logistics, smart cities, smart buildings, to agriculture. In addition to struggling with cellular at high speeds.
5G network technology is also possible to have an impact on other sectors such as transportation, housing, to the workplace.
New technology based on 5G wireless technology applications will control several jobs such as auto piloting a car (without a steering wheel), telephone with holographic calls, and creating reality anywhere and anytime.
As with 4G networks, 5G operates on the same cellular network principles. However, the air interface for 5G networks can further enhance flexibility and much higher scalability.
The difference between 5G networks and previous generations of cellular networks is that the 1G network provides analog voice.
Then 2G introduces digital voice, 3G provides cellular data, and 4G LTE ushers in the era of cellular broadband.
5G High Radiation Effect
One of the things that most users of this network fear is that the radiation from the radio signals emitted will cause cancer.
A report from the World Health Organization (WHO) in 2011 stated that cellphone radiation is something that must be register as a source of carcinogens to humans.
In 2016, a study funded by the US government suggested a link between radiofrequency radiation and cancer in mice.
In addition, there are some popular cellphones such as the iPhone and Samsung Galaxy allegedly passing the radiation limit set by the FCC.
However, the accusation leveled against cell phone radiation causing cancer is an exaggeration.
Because there could be many other things that if also have a danger to carcinogens. FCC Chairman, Aji Pai stated that smartphones currently used, including 5G networks, are safe and ready to use.
Who is Using 5G? ( 5G Users )
Since 5G network technology was first released in 2016, its use has been applied in various countries. Its first users are America, Europe, to East Asia which consists of the United States, South Korea, Japan, and China.
However, the first commercial use of 5G was carried out in January 2020 in South Korea and was followed by other countries.
According to the GSMA, 5G networks could reach 1.2 billion connections by 2025 covering a third of the world’s population.
Mobile phone companies such as Samsung have released phones that can serve 5G network technology to countries that already provide it.
Although the presence of 5G technology as the successor of 4G and LTE is getting closer and a number of countries are implementing this latest technology. There are still many questions raised about its presence.
This is quite reasonable considering that 5G network technology will have a big impact on its users in all corners of the world.
As for some examples of 5G users as consumers, such as Augmented Reality (AR), Virtual Reality (VR), enhanced Mobile Broadband, and cloud gaming.
Then there are several examples of 5G users engaged in the industrial/B2B sector, including smart seapots, remote surgery, drone surveillance, smart factories, remote controlling machinery, and many more.
Advantages and Disadvantages of 5G Technology
Advantages of 5G Technology
As mentioned earlier, the 5G network has contributed significantly to the advancement of human communication.
Thanks to 5G, human daily activities in the field of communication and data exchange have become easier and faster.
Wider Connection
Even though they both carry OFDM. 5G technology offers advantages over LTE which only has a subcarrier spacing of up to 15 kHz. While 5G can be more than that.
With a large capacity, which is up to 100 times, 5G technology is also able to adapt to various devices. This means that more and more smart-based devices can connect and adapt to 5G networks.
2. Almost No Delay
In addition to wide connections and better transmission speeds than previous generations, 5G technology also has almost no delay. It is known that 5G networks have a delay time of about 4 to 5 milliseconds.
In fact, it can be reduce to 1 millisecond. This short delay time allows users of 5G technology to watch high-resolution videos without buffering.
3. Energy Saving
Since the beginning, 5G technology has been present to reduce energy consumption. Its ability to reduce energy consumption by 10% is done by reducing data traffic.
The super-fast data transmission speed also makes the biggest contribution to creating energy-efficient technologies.
Simply put, 5G networks are greener and more data bits per kilowatt of energy than previous generations.
Disadvantages of 5G Technology
Behind these extraordinary advantages, it turns out that 5G has several drawbacks that you may not be aware of. What are the drawbacks? Here’s the review.
1. Full Radio Frequency
As we know, the radio spectrum is currently full of 3G and 4G which were already present. It is not impossible that the presence of a 5G network of 6 GHz will cause problems because the arrangement of radio frequency bands is already congested.
2. Privacy and Security
Research results say that 5G has problems in terms of privacy and security. The ease of transferring high-quality data is allegedly the cause of the vulnerability of 5G technology.
3. Minimal Penetration
One more drawback of 5G technology that you may not know about. Despite having a wider connection, 5G technology has very minimal penetration power.
Unlike its predecessor network, the 5G network is less than optimal to penetrate barriers such as buildings, walls, concrete, trees and other barriers.
