Advantages and Disadvantages of 5G Network
5G technology has been launched and used by various latest gadgets such as Huawei, which had a dispute in the United States. Michael Lemke, a physicist with a Ph.D. from Dresden University of Technology, is said to be the inventor of this fifth generation 5G technology.
The development of the latest technology, named 5G, is a breakthrough that can improve data transmission and exchange. In 5G technology, data will be transmitted via radio waves. Radio waves will be divided into different frequencies. Each frequency is set up for a different type of communication, such as aeronautical and maritime navigation signals, broadcast television, and mobile data.
With the increasing speed of data transmission provides various benefits in areas that are always associated with data exchange such as communication and the internet. But what are the advantages and disadvantages of this 5G technology?
In this article, Nata Connexindo will discuss the advantages and disadvantages of 5G technology. Read more here
Advantages of 5G Technology
Like all breakthroughs in the world of technology that have direct benefits, 5G technology also holds many benefits that can be used to facilitate daily activities, especially in the field of communication and data exchange. If previously it took a long time to transmit large data, then through this technology the transmission time can be cut significantly. What are the advantages of 5G technology?
Much Better Transmission Speed
Compared to the technology used by LTE and W-CDMA which only supports frequencies up to below 6 GHz, 5G NR supports frequencies up to 100 GHz. This means that 5G technology is capable of producing transmission speeds of up to 10 GB per second. Therefore, compared to LTE, 5G NR still uses OFDM (Orthogonal Frequency Division Multiplexing), but of course with some improvements. One is flexible subcarrier spacing, not just a single value. This helps 5G NR to handle a wide spectrum of frequencies and uses. The transmission rate is so fast it is not surprising that 5G is seen as a very revolutionary technology in supporting fast communication between two parties.
Almost No Delay
Not only can 5G offer higher data transfer rates, it also offers lower latency and higher connection density than previous generations. 5G technology allows a delay time of only about 4 to 5 milliseconds. In fact, it can be reduced to 1 millisecond! That is, 10 times faster than 4G. This allows us to watch high-resolution videos without interruption. When juxtaposed with IMT-Advanced aka 4G, IMT-2020 aka 5G can provide 10 times through-put, 10 times reduced latency, and 10 times connection density. This new generation is designed to connect more and more devices, not just smartphones.
Wider Connection
With the flexibility of using radio frequencies, 5G technology is able to adapt to various devices. This means that 5G technology allows it to be used on more devices. More precisely, the capacity is up to 100 times greater. This allows more people to communicate with each other at the same time. In simple terms, even though they both use OFDM, 5G offers advantages over LTE. One of them is the subcarrier spacing of 5G which can be multiples of 15 kHz. LTE itself can only be 15 kHz. The number of devices that can be connected to 5G technology makes all the possibilities of devices connected to this technology such as various smart-based devices such as in smart homes.
Energy saving
The super fast transmission speed makes the use of 5G technology save energy. This is because from the start the 5G network aimed to reduce energy consumption by 10% compared to 4G. The latest 5G protocol is to reduce power consumption by reducing data traffic. In addition, the sleep mode feature will be further improved. This is what will make the 5G network more energy efficient. Given the very high transmission and data traffic, a better transmission speed is needed. According to GSMA on The Mobile Economy 2018, mobile internet users in 2025 are predicted to reach 5 billion, up from 3.3 billion in 2019.
Disadvantages of 5G Technology
Almost every technological invention, in addition to being accompanied by great benefits, also has hidden shortcomings. This 5G technology is no exception. Various shortcomings ranging from potential security lurk users of 5G technology. What are the disadvantages of this technology.
Minimal Penetration
One of the drawbacks of 5G technology is that the penetration power is still very minimal. Unlike previous technologies that are able to penetrate barriers such as walls and concrete quite well, 5G technology is considered less than optimal to penetrate barriers. The bandwidth used in 5G technology increases, therefore the area that can be covered is reduced. Devices that use 5G technology cannot reach as wide as 4G. Of course, it will affect the area that can be reached by 5G towers later. The millimeter waves used by 5G have low penetrating power. Cannot pass through buildings, trees, walls and other obstructions without any disturbance at all.
Full Radio Frequency
The use of radio frequencies that are already congested is an obstacle in itself to take advantage of 5G technology. The radio spectrum is already full with the presence of 3G and 4G which are the predecessors of 5G. Coupled with the presence of 5G later, of course it will be even more full. Additional 5G network frequency coverage of 6 GHz, which is already full of other signals. The density of this radio frequency can certainly cause new problems.
Security and Privacy Issues
Several studies conducted by the University of Lorraine and the University of Dundee concluded that 5G technology will have security problems. This is mainly because of the features that facilitate the transfer of high-quality data. Can make it easier for attackers to come into the system. The issue of privacy and security on the internet has indeed become an important problem in a world that is starting to rely heavily on the internet network.
