In telecommunications, 5G is the fifth-generation technology standard for mobile broadband networks. Mobile operators began deploying worldwide in 2019, and are the planned successor. The 4G networks provide connectivity to most current mobile phones. Like its predecessors, 5G networks are cellular networks, where the service area is divided into small geographic areas called cells. All 5G wireless devices in mobile phones are connected to the Internet and phone networks. By radio waves through a local antenna in the cell. The new networks have higher download speeds, eventually reaching 10 gigabits per second (Gbit/s).
In addition to being faster than current networks, 5G has more bandwidth and can connect more different devices, improving. The quality of internet service in crowded areas. Due to the increase in bandwidth, the networks are expected to be increasingly used. General network service providers for laptops and desktops, competing with existing network services such as cable networks. And will also enable new applications in the Internet-of-things (IoT) and machine-to-engine area. Cell phones with 4G capabilities alone cannot use 5G networks.
5G development history
What is 5G?
5G is the fifth generation of mobile phones. Up to 100 times faster than 4G, 5G creates unprecedented opportunities for people and businesses.
Faster connections, lower latency, and more bandwidth are powering society, transforming businesses, and improving today’s experiences. Services we once considered futuristic, such as e-health, connected cars and transportation, and advanced cloud gaming, have arrived.
With 5G technology, we can help create a better, safer, and more secure future.
How fast is 5G?
5G download speed can reach 1000 megabits/s (Mbps) or even 2.1 Gbps. To demonstrate this, a user can play a YouTube video at 1080p on a 5G device without buffering. Downloading an app or an episode of a Netflix show, which can now take a few minutes, can be done in seconds. Wireless video streaming in 4K will also become more affordable. If on mmWave, these examples must be in a city without the influence of a 5G hub; otherwise, the download speed will fall back to 4G.
The low band can close to 5G over long distances, and while the overall speed of low-band 5G will be slower than mmWave, the low-band should still be faster than what is a good 4G connection. Low-band 5G download speeds can be as high as 30-250 Mbps. Low-band 5G will most likely be available in more rural areas. Mid-band 5G download speeds can reach 100-900 Mbps and will likely be used in large cities.
What are the benefits of 5G?
Although the disadvantage of 5G is the fact that it is easy to block mmWave, or the many uncertainties of radio waves (RF) are limited, 5G still has many advantages, such as:
improve mobile broadband;
low delay 5ms;
Higher data transfer enables new possibilities on 5G networks, such as 4K streaming or near-time virtual reality (VR) streaming; and
The possibilities of 5G mobile networks include low-band, medium-band, and mm-wave frequencies.
How 5G Works
Like other mobile networks, 5G networks use cell phones that divide their area into sectors and send coded data over the radio. All cell sites connect with the network, either via cable or wireless backhaul. 5G will change the way data is encoded and give airlines more options for how to use radio waves.
5G networks use an encoding type called OFDM, which is similar to the encoding that 4G LTE uses. The air interface design for the mobile for lower latency and more flexibility than LTE, however. The new system opens up “high-band,” short-range airwaves that don’t work with 4G technology. But 5G can run at any frequency, giving us a variety of 5G experiences – low, medium, and high.
What 5G phones are available?
A phone or other hardware device cannot receive a software update on a 4G phone to support 5G. 5G requires special equipment. To use 5G, a user must have a 5G-enabled device, a service provider that supports 5G, and live in an area that has 5G coverage.
Some examples of 5G-enabled phones include:
TheSamsung Galaxy S10 5G
Samsung Galaxy Note10+ 5G
Samsung Galaxy A90 5G
OnePlus 7 Pro 5G
Xiaomi Mi Mix 3 5G
Huawei Mate X
Huawei Mate 30 Pro 5G
