5G and Its Usefulness In The Future


If you are now satisfied with the ability of your smart phone that can take photos, can search, or surf the internet, or even play music for you, then soon you will feel that the smart phone can no longer meet your expectations.


Technology does promise a better life, including the development of super-fast wireless cellular networks.


Internet speeds that will be more 'fast' and more reliable will be presented on your mobile.


But more than speed, 5G technology will fulfill all your expectations about connections that are very reliable and fast, and that is very important in technological development, especially if we refer to 'virtual reality', autonomous cars, 'smart city', drones for shipping , and devices that are connected to each other.



What is 5G?


5G is the next generation of broadband connections.


5G is generally seen as the fifth generation cellular network technology that provides broadband access.


The emergence of 5G will bring new capabilities to mobile devices that will expand storage capacity requirements. Which in 2019 can reach 512 GB. It is projected that in 2021 it will reach 1 terabyte.


Data transmission speeds of up to 20 Gbps, and bandwidth that allows connection to many devices at the same time including sensors and other "smart" devices such as autonomous vehicles.



History of the Development of Cellular Technology.


1G technology


1G technology is analog cellular.


In 1981, analog cellular technology was only for sound. Does not offer storage. There is also no data processing on the device.


Transmission speed is at 2.4 kilobits per second (kbps) or less.


Mobile phone coverage is very limited. Likewise signals that are very susceptible to interference.


2G technology


2G technology is the first generation of digital cellular technology, as we found in CDMA, GSM, and TDMA.


In 1991, this analog cellular technology switched to digital cellular technology, which was used for voice communication. Also to accommodate text messages. Likewise data storage and processing capabilities are still very minimal.


Data transmission speeds increase up to 40 kilobits per second (kbps).


3G technology


3G technology, carrying speeds from 200 kbps to several megabits per second, such as EVDO, HSPA, and UMTS. This happened in 1998. At that time cellular phones could store data ranging from 32 Megabits (MB) to 16 Gigabit (GB). And it can also be used to browse the internet.


Data speed increases to 21.6 Megabits per second (Mbps).


4G technology


4G technology is the next leap forward. Storage increases up to hundreds of megabits and even speeds of gigabit levels, such as WiMAX and LTE. This 4G technology began in 2008.


Data optimization supports video streaming.


Storage memory increases to 16GB-256GB, and transmission speeds increase to 1 Gigabit per second (Gbps).




In 2019, the 5G era begins!



How 5G works


Like other cellular networks, 5G networks use a cell site system that divides its area into sectors and sends data encoded through radio waves. Each cell site must be connected to the network backbone, either through wired or wireless backhaul connections.


The 5G network uses a type of encoding called OFDM, which is similar to the coding that uses 4G LTE. The air interface will be designed for much lower latency and greater flexibility than LTE.


The new system is also designed to operate on channels that are much larger than 4G, to bring higher speeds.


Most 4G channels are 20MHz, tied together up to 160MHz at a time. 5G channels can reach 100MHz, even Verizon uses as much as 800MHz at a time.


5G networks must be much smarter than the previous system, because they make more smaller cells that can change size and shape. Even Qualcomm, with existing macro cells, said that 5G would be able to increase the capacity of four times the current system by utilizing wider bandwidth and advanced antenna technology.


The aim is to have a much higher speed, and a much higher capacity per sector, at a much lower latency than 4G.



What is the use of 5G technology?


Ideas for streaming games, ways to do stroke rehabilitation through 'Virtual Reality', or smart bandages that track your healing, or maybe parents' ways to interact with babies in an incubator. All of these ideas require high bandwidth, low latency. And that is only possible by a technology called 5G.


At this stage, as I mentioned at the beginning of this article, it turns out your smart phone, has not fall under the smart class, to be able to recognize your face, or translate a speech, or even drive a car or fly a drone. And this is what is called artificial intelligence.


The main reason we use cellphones today is not really smart, because they don't have the same qualities that our minds have, namely: memory and processing speed.


Fast processing speeds, low latency, high bandwidth, and greater storage capabilities offered by 5G wireless technology, will eventually bring intelligence to mobile devices, to rival the human brain.




In the end, you will be able to buy cellular phones that support 5G in 2019. The vendors include big names who have been leading the mobile phone industry, namely: Samsung, Huawei, Xiaomi, LG and ZTE.


The types are in the following list:


Xiaomi Mi Mix 3 5G

LG V50 ThinQ

Huawei Mate X

Samsung Galaxy S10 5G

Samsung Galaxy Fold

ZTE Axon 10 Pro 5G

OnePlus 5G phone


Happy enjoy 5G service!
