According to some sources, it is suggested that a new generation of 5G may be introduced in the early 2020s
What is 5G?
5G is a fifth-generation mobile network which is one step ahead in mobile technology. It will be on next telecommunication standers and will be more advanced from 4G/IMT-Advanced. 5G is the data which is going to be used in the future for our phones and tablets. It is very similar to the LTE (Long Term Evolution) standers which are working for the 4G system. Just have a look at the history of this new mobile generation. First 1G system (Introduced in 1982), a first 2G system (Introduced in 1992), first 3G systems (introduced in 2001) and first 4G system (Introduced in 2012). The number of companies is increasing for investing in the preparation for the new mobile wireless standard but there are eight criteria have been set to be qualified from the (GSMA) Group Special Mobile Association:
One to 10Gbps connection to endpoints in the field
One millisecond end to end round trip delay
1000X bandwidth per unit area
10 to 100X numbers of connected device
(Perception of) 100 percent coverage
(perception of) 99.999 percent availability
90 percent reduction in network energy usage
Up to ten-year battery life for low power, machine-type device.
Along with above 8 criteria 5G network also needs to have (Internet-connected device), as well as broadcast-like services and life line communication in times of natural disaster.
Difference between 5G and 4G
With 5G you can communicate so fast that it becomes almost real-time communication, putting mobile internet services on par with office services, on the other hand, 4G provides an additional speed boost to the growing business services such as mobile video conference and cloud computing. 4G also provides very cost-effective international calls on data calling services.
4G network mostly focused on the availability of raw bandwidth, while 5G mainly focus on providing worldwide connectivity to lay the ground for the fast and the flexible access to the internet user whether you are on a top of the building or down under a subway station.
Advantages and Disadvantages:
5G would be more effective, efficient and significantly faster than 4G providing higher productivity across all capable devices with a theoretical download speed 10,000 Mbps.
Along with all this superb facility, it will come with a big cost concern. All new mobile phones are manufactured with the 5G integration but this system will not support to old mobile phones hence people have to buy new phones else this facility is useless for them so it would be an expensive affair.
Technology is still under process and research on its viability is going on.
The current 4G mobile network has the potential to provide 100s of Mbps. While 5G provides multiple gigabits per second but the speed, this technology is claiming seems difficult to achieve (in future, it might be) because of the incompetent technological support in most parts of the world.
Mobile Companies who are working on the 5G system:
Samsung: Electronics giant Samsung has conducted the trial using the 5G base station and 5G mobile phone prototypes compliant with 5G technology. They have achieved the download speed of 1 Gbps over a 2Km distance at the microwave frequency of 28 GHz. the products showcased included consumer devices for fixed wireless access connectivity. Samsung also has expanded its tablet portfolio with Galaxy Tab S3 and Galaxy Book and outlined a series of measures to “enhance” product safety.
Nokia: The Company NOKIA has demonstrated 5G technology based prototypes showing peak data rate speed of over 30 Gbps. The technology will serve more than 1 million 5G phones in a single cell simultaneously.5G FIRST builds on our commercial 5G Nokia AirScale and AirFrame platforms to provide a versatile solution that spans the network.
