what is the 5th generation of internet or 5G?
In the coming years, with the advent of the fifth generation internet, we will see lots of changes in the individuals lifestyle.
5G is the fifth generation of mobile networks. this is the next generation of mobile technology that will be used by future handsets and tablets.
History
the first generation of cellular networks came around 1982, which was using the analog system and was named contractually 1G. this system was completely analog until 2G second generation internet was launched in 1991 which switched to digital. 2G also added mobile data in the form of GPRS and EDGE technologies. Nearly 10 years later, the 3G network was launched, which gave users more speed than the second generation. Nearly 10 years later our current LTE networks were launched. which we call it the fourth generation or 4G. Historically, every 10 years, a new generation of network technology is being used. The fifth generation of the Internet or 5G will evolve, such as the leap of previous generations, on things like speed.
When will launch 5G?
By assuming the same 10-year pattern for changing the generation of mobile networks, we can see the fifth-generation commercial (publicly available and commercially available) handsets in early 2020.LTE began operating around 2011, so according to the model, this generation should be expected by 2021. Of course, we will soon see some of the features of this generation if network providers and other stakeholders in this field can predict and work for it.
Qualcomm plans to release its first 5G products at the 2018 South Korean Olympics. As for the use of the 4G Internet, we needed phones that could support this generation. To use the fifth-generation Internet, we also need to use handsets that cover this generation.
What is the difference between 4G and 5G?
The fifth generation of the Internet is still a brilliant idea in the distant future, so do not be fooled by companies and speed testing ads. A 5G network has features beyond the ones designed for 4G, at this moment we simply do not know what we’re up against. Contemplation is reported at high speeds at just a few gigabytes, but We do not know exactly how the situation will be.
Companies such as Verizon, AT & T, Intel, Qualcomm have conducted tests for the fifth generation, and these preliminary tests are likely to form the international standard for this generation. One of the common features for the 5G is the use of the mmWave transmission waveform or millimeter wave that can be the key to speeding up the 5th generation Internet with its promise.
What is mmWave technology? Why is it better?

Mobile phone technology is transmitted through radio waves, which are categorized by different frequency electromagnetic signals: higher frequency, smaller wavelengths. Thus, the millimeter wave is related to a signal measured in millimeters and generally defined between 30 GHz and 300 GHz.
Millimeter wave technology gives us more data capacity
A simple rule is that more data can be moved at higher frequencies. For example, an FM wave that only transmits sound is normally rotated between 87.5 and 108.0 megahertz, but LTE transmits much larger data between 700 and 2100 MHz. The millimeter wave offers more bandwidth than it does on LTE. (This process of electromagnetic spectrum can also be extended to light, and is one of the reasons why the optical fiber is so fast).
Another advantage of short wavelengths used in a millimeter wavelength is that the antennas transmit and receive signals become smaller, and this makes the phones to use several antennas for different wavelengths in a device, which speeds up even when several users connect to it. Of course, this technology also has its own special challenges, because with increasing frequency, the range of transmission will be reduced and the wavelength will be reduced, and this will be a problem for the wave that must pass through walls, buildings, and even raindrops. Initial experiments on the fifth generation focus on these same problems and provide solutions.
4G problems
What we use as 4G is not really 4G. According to the standards, what we use as 4G should be about 1 GB in static mode and speeds up to 100 MB / s in motion mode, which, based on the 4G objective evidence we use, is not the fourth generation . However, we hope that the speed of the Internet of fifth generation will be as promising as it should be.
The fifth-generation Internet is likely to speed around 10GB / s, which is several times more than the size of the fourth-generation Internet. It should be noted that some large companies in Australia, such as Vodafone, Telsra and even Huawei, are preparing for a new generation of mobile networks.
Internet of Things
The fifth generation of the 5G or 5G is a kind of Internet infrastructure of the Internet of Things, which can have a tremendous impact on human life. The Internet will be available with appropriate bandwidth, connection costs will be reduced and many devices will be connected to the Internet. Smart houses and smart cities are the goals of this Internet. Technology cost will drop. Be sure to see more Internet objects (IOT) and 5G over the next few years.
Is It Easy To Get To 5G?
The wireless or wireless industry will announce the launch of 5G in 2020; Nokia and AT & T say it’s time-consuming and can be upgraded to the consumer by that time. Craig Wigginton, a telecom activist, believes the year 2022 is a bit more realistic. Todd Sizer, director of research at Alcatel, says the technology will not be available until 2025. In any case, the 5G will eventually come to a halt, and to deliver it to consumers, service providers will have to increase the capacity of their smartphones and telecommunication antennas much higher. By installing more antennas, they can use frequency spectrum. The waves and radio frequencies are measured in terms of current or GHz, currently, smartphones use frequencies below 3 GHz, 5G requires higher bandwidths. For now, the problem is that higher radio frequencies can not work from distant distances or when walls are placed between them and the mobile device. To solve this problem, the service providers have to focus on the new technology of telecommunication antennas. Antennas with a very high input and output capability can send many radio waves in parallel and define a beam of signal, which ultimately causes radio energy to move to a specific path (which The user is located in that building-located).
5G
Servers now have to close many of these antennas in order to work on this technique so that they can provide all users with an acceptable quality rating of 5G. They also try to add high-level antennas (macrocells), each supporting up to 32 km. On the other hand, installing small cells or antennas that support only a limited environment is also required.
“Installing any macrocell costs $ 100,000, while installing a small cell costs just $ 10,000,” says Femi Adeyemi, a Fujitsu administrator.
It’s too early to say how much 5G will be available to users. Dan Warren, a senior GSMA mobile phone company, says: “Telecom companies that now cover the 4G network, if they want to move to the next generation will generally cost $ 1.7 trillion. With such a huge expense, you should not expect this service to be at a low cost to users. “
Why should we be keen on 5G?
So far, we’ve outlined some of the easy-to-use, high-speed Internet applications. Let’s go to other applications.
The New Realm: A massive 5G offering makes virtual reality and augmented reality all the more widely used. The augmented reality allows users to access a lot of information; for example, they simply recognize their route; identify price tags on products and bar codes; send data to the front of the car when The smart car is driving. On the other hand, virtual reality will bring a completely artificial look. An important point in using virtual reality is that both require very fast internet connection.
High speed: The download speed is 4G to 150 Mbps, while the 5G speed is 66 times higher and 10 gigabits per second. This speed is so high that you can download a full movie in just 4 seconds.
Very fast response: A few seconds when implementing an online video does not matter much, but this delay is not acceptable at all for a non-driver car, where the millisecond is strong. Using a 4G connector, an intelligent car takes approximately 15-20 milliseconds to tell the intelligent car behind it that it compresses the brakes; this amount of time reaches 1 millisecond in a 5G connection. In total, it can be said that, as the download speed increases dramatically, the initial delay in this kind of communication is, as far as possible, eliminated.
