Why does it have to be 5G?

5G is considered capable of answering consumer needs for faster data and higher capacity.

"Because the number of consumers is increasing, more and more customers must have technological breakthroughs to meet their needs," said Qualcomm Technologies' Senior Development Business Manager, Dominikus Susanto, in the "Snapdragon Academy" media workshop in Jakarta, Thursday, December 20, 2018, as reported by Kantor Antara News.

The benefits of 5G technology, according to Susanto, can not only be felt by users, but also network operators who will benefit by accommodating more customers.

Enhancing 5G technology is in accordance with three fundamentals in increasing connectivity, namely coverage, spectrum and capacity.

One thing that is quite decisive from network quality is coverage or coverage area. Susanto analogues the coverage area with water ripples where the farther from the center of the wave will be weaker.

Disruptions that exist within the coverage area are also things that determine network quality. The disorder in question, according to Susanto, is like a wall and a building.

"Noise or interference cannot be eliminated, because there will be many other networks that use the same signal. So there is a need for technology that can filter out these things," Susanto said.

Some new network technologies such as 4G and 5G, according to Susanto, have used technology that can use multiple recipients and senders at once or called multiple-input multiple-output (MiMo).

Furthermore, for the spectrum, Susanto said it was regulated by the governments of each country, but the spectrum could not be easily added.

To overcome this, network technology is created that can fill the empty frequency spectrum, namely the presence of 5G networks. "We can use a higher frequency, more precisely above 24 GHz," Susanto said.

This frequency, according to Susanto, is still not used for communication channels, so it can create a new path.

5G networks also have technology that can 'use two types of spectrum networks, namely licensed spectrum, such as operator networks, and unlicensed spectrum, such as bluetooth and Wi-Fi.

"Licensed and unlicensed combine so much faster," he said.

Finally, capacity. Susanto analogues this with a water pipe, when it is poured in one bucket it will be fast, but when water sources are used by several taps simultaneously, the speed will decrease.

Susanto said that 5G technology was able to answer that by making higher speeds, lower latency and greater capacity.

The benefits of Susanto's 5G technology say that 5G technology can be used in industrial fields, such as automation of machinery in factories.

"Or, for example, street lighting, with the Internet of Things (IoT) all connected, or can find out which street lights are dead which must be replaced," Susanto said.

Another example, he said, was an electric meter. With 5G technology, the officer no longer records manually, because it can be done automatically.

"There is no need to use humans to check the amount of electricity consumption. In addition, 5G is very giving opportunity for new industries for new service providers to emerge," Susanto said.

Not only that, 5G technology can also be used for swak driver cars because of low latency, also enriching entertainment content - not only limited to videos and photos, but also augmented reality or Augmented Reality (AR).
