5G or the 5th generation network in cellular technology is known to provide access to broadband with better and faster connectivity and internet access. 5G is followed by 2G, 3G, and 4G respectively and offers further reliability than its predecessors. 5G in general terms refers to any system the uses the 5G NR or the 5G New Radio software.
The concept of 5G has been given its shape by combining the cutting edge technology of networks with top-notch research works. The materialized version of this grand idea has been estimated to offer better performance with an average speed of download of 1GB/s.
How it works?
It this system or organization of the network, the service area under each provider is divided into smaller sections of geographical areas known as cells.
Signals that represent images and sounds are termed as analog signals which are eventually converted into digital signals using converters, to be understandable by devices like cell phones. These converted signals are then transmitted in the form of bits in streams. The 5g devices use antennas or a transmitter and receiver combining system to operate or transmit signals as radio waves. These antennas are connected to the Internet or telephone network via Optical fibers of high speed and efficiency. A mobile device that is a part of this networking system gets seamlessly connected to an antenna of a new cell.
The newly designed wireless devices with a 5G network also have to capability to shift to 4G network as these devices use 4G so as to establish the initial connection with their respective cells. The provision of the capability to shift to 4g also comes useful in places that do not have accessibility to the 5G network.
Speed and coverage
The 5G speed has variations when it comes to the location, carrier, and device. However 5G is definitely better and faster than 4g so, it is always more preferable over 4G. The speed of the 5G network, as said earlier is also considerably much higher than that of 4G with the same proportion of spectrum and the same number of antennas.
A 5G network is capable of supporting devices up to a million, in each square kilometer which is pretty admirable when compared to a 4G network that supports up to 100,000 numbers of devices in each square kilometer.
While using the 3GPP networks though, 5G can work slower than a few highly advanced 4G networks. The spectrum of millimeter waves, which is not as common for use, can exhibit better speed in the 5G network. The air latency target for 5G networks is 1 to 4 milliseconds. According to recent reports, the 5G has achieved an air latency of 8 to 12 milliseconds.
Application of 5G
5G is not only used in mobile devices like cell phones but has a variety of other applications. 5G can be used in providing access to a communication system between vehicles and different infrastructures. Companies promote the use of 5G in automation industries as well. 5G also has effective use in the departments of public safety. Fixed wireless also intends to use 5G connections instead of fixed broadband.
When and where was 5G launched?
5G started off as just as an idea and has finally come across all its way to achieve the shape and establishment it can gain today. 5G was launched in the United States in April of 2019 and the new version of the network was appreciated all over .currently, the 5g network is not accessible worldwide and is available only in certain parts of the world that mostly includes parts of Chicago and few more places. Only two available handsets exist at the moment. In the places where 5G is accessed, the average speed of it has successfully topped the utmost speed of a 4g network. The drawback of 5g that has been discovered lately is that the coverage of a5G network is inconsistent with a large gap between the highest and lowest speed. This makes the newest version of the network slightly unreliable in certain locations.
The carrier to launch 5g in the UK is EE. The network was available in 3o cities by the 30th of May, 2019. The carrier has declared to provide access to 5G to 10 more cities in the UK by the time 2019 ends. In London, 5G has a range of speed lying between 200 Mbps and 500 Mbps which is also faster when compared to 4G but not as fast as in Chicago.
There have been plenty of announcements made this year about the launching of 5G phones by a few brands but only a few companies have fulfilled their statements and introduced 5G phones to the public. The handful number of such devices and made the choice very limited and regional. Combining the United States and the United Kingdom, There are a total of about some 10 companies that have launched handsets with a 5G network.
5G was visualized as a new step towards the advancement of the networking system that will lead to the benefit of several IT-based industries and also come to effective use for the common citizens of all across the world. 5g is therefore expected to open up new doors in the technological sector by being able to carry data in large amounts with great speed, thereby leading to a more connected and smarter world. Now, only time will say how much is 5G able to reach and ultimately top its expectations.
