ADVANTAGES AND DISADVANTAGES OF 5G

5G is a term we are already familiar with today. Along with the very rapid advancement of technology and society's growing need for technology, network technology has also been developed, from 2G, 3G, and 4G networks to the latest one, 5G.

As quoted from Qualcomm, the 5G network is the fifth generation (fifth generation) of cellular network, promising download and upload speeds 10 to 20 times faster than previous generations of internet. In practice, this technology is intended to provide users with convenience in terms of information speed, low latency, wide network connectivity, and greater network capacity. In short, with this technology, internet-related activities can be carried out 500% faster than 4G LTE, which is still the mainstay.

On 27 May 2021, Indonesia began adopting the fifth-generation digital feature known as the 5G network, which was officially launched in Indonesia. At present, Indonesians are still more familiar with third-generation (3G) and fourth-generation (4G) network services, and 4G services are still not fully reachable in some locations in Indonesia, especially outside Java. The growth of fifth-generation technology in Indonesia has not been widely studied.

Advantages

As mentioned at the beginning, the 5G network makes a fairly large contribution to the advancement of human communication. Thanks to this network, people's daily activities in communication and information exchange have become easier and faster.

• Wider Connectivity

With its large capacity, up to 100 times, the 5G network is also able to adapt to various features. This means that more and more smart-based features can be connected to and adapt to the 5G network.

• Almost No Delay

Not only does it have wide connectivity and better transmission speed than previous generations, but the 5G network also has almost no delay. The 5G network is known to have a delay of only around 4 to 5 milliseconds. Moreover, it can be reduced to 1 millisecond. Such a short delay allows 5G network users to watch high-resolution video without buffering.

• Energy Efficient

Since the beginning, 5G technology has been designed to reduce energy consumption. Its ability to reduce energy consumption by 10% is achieved by reducing data traffic. The super-fast data transmission speed also makes the biggest contribution to creating energy-efficient technology. Simply put, the 5G network is greener and delivers more data bits per kilowatt of energy than previous generations.

Disadvantages

Behind these extraordinary advantages, 5G in fact also has some disadvantages that may go unnoticed.

• Crowded Radio Frequencies

As is already known, the radio spectrum is currently full with 3G and 4G networks that appeared earlier. It is quite possible that the arrival of this 6 GHz network will cause problems because the radio frequency band is already crowded.

• Privacy and Security

Study results indicate that the 5G network has problems in terms of privacy and security. The ease of transferring high-quality information is suspected to be the trigger of the vulnerable security level of this network.

• Limited Penetration Power

Although it has wider connectivity, this network still has very little penetration power. Unlike its predecessor networks, it is less effective at penetrating obstacles such as buildings, walls, concrete, plants, and other barriers.
