During this time, we will hear news about 5G, whether from the major network operators, many camps. They are preparing for public relations. And show the ability of 5G on the frequency 26.5 – 27.5 GHz, including the announcement of the sale of mobile phones supporting 5G from the side of the mobile phone brand. We can only expect that 5G must be better than 4G because more than 5 is more than 4. We should come to know what 5G is, how good it is and what it has to do with us?
Before reaching 5G, let's get to know each G (Generation) first.
- The 1G era, that era is the era where we talk via voice over analog mobile phones.
- In the 2G era, we can send MMS messages to each other.
- 3G era, we connect and use the internet to transmit data via mobile at speeds between 20kbps- 42.2Mbps
- 4G era, we can see audio images. or online movies at speeds increased to 100 Mbps (4G LTE), 150 Mbps (4G LTE Cat.4) and 1,000 Mbps (4G LTE Advanced).
5G Era (Generation 5)
It can be said that it is the 5th generation of communication that the future will no longer be just a mobile phone. But it will include all devices that can connect to the Internet (Internet of Things or IoT). If we enter the 5G era, we will be able to download videos, movies or apps at speeds of up to 10,000 Mbps if using 4G. Watch online videos (8K size) or Downloading a movie takes 6 minutes, but if you have 5G, it only takes 6 seconds! Wow.. very fast
How is 5G superior to 4G?
The response is faster. If we use 4G, we can control things as fast as 20-30 ms (Milli-second 1:1,000 seconds), but if we use 5G, the command to control devices that connect to the Internet is 10 times faster.
More data traffic than 4G, with 4G being able to receive only 7.2 Exabytes of data per month, but 5G will give us a 7X increase in data traffic, which is 50 Exabytes per month.
5G has more frequencies for use. So we can use the frequency up to 30GHz.
5G guarantees more users in each area, where 4G can support about 100,000 users per 1 sq km area, but 5G will support 10 times more users / 1 million users per area 1 sq km
It transfers more data per second than 4G. 4G transfers only 1 GB of data per second, but 5G can transfer up to 20 GB per second, or 20 times that of 4G.
How does 5G affect our daily lives?
Of course, in the 5G era, it will allow us to watch movies, listen to music, play games, open mobile websites faster without interruption, even high-definition videos. But the benefits of 5G don't stop there. because in the future The world will step into IoT technology will see the work of devices connected to the Internet, not just smartphones. Devices connected to the Internet via 5G will send information to together more efficiently for example Driverless cars that in the future will be able to interact with another car and the road (Smart Road) through sensors, with 5G transferring data between them.
Including Virtual Reality (VR) and Augmented Reality (AR), such as watching movies or playing games via VR devices, if using 5G will get a better experience than playing via smartphones today. And most importantly, AR brings 3D virtual images into the real world through the camera. And it is processed by making 3D objects (virtual images) overlap with the real image as a single image. Which images or videos that have to be pulled from the cloud make 5G play a big role in pulling information to appear on the screen without delay.
In conclusion, in the 5G era, our home will be able to watch videos, play games, listen to music without interruption. But if it's about IoT, we'll have to wait and see for a while. As soon as it happens, 5G will definitely be worth it.
OK, what is 5G?
Before reaching 5G, we started with 1G. That era was the era where we talked via voice over analog mobile phones. Until we send MMS messages to each other in the 2G era, then we enter the 3G era where we connect and surf the Internet via mobile with higher speeds between 20 kbps and 42.2 Mbps and arrive in the 4G era where we can Watching pictures and audio or movies online is enough because of the speed increase such as 4G LTE (100 Mbps), 4G LTE Cat.4 (150 Mbps) and 4G LTE Advanced (1000 Mbps).
