what does 5g mean
What is 5G technology As 5G coverage expands worldwide, there are more questions than answers about this technology.
In this article, we will explain everything about 5G technology.
We’ll cover how the 5G network works, what happened to its 3G and 4G predecessors, and what exactly are the best 5G phones running on Android.
Just follow this topic to learn about this great technology that will revolutionize the mobile networking world in the next few years.
what is 5g network
5G refers to the fifth generation mobile network.
After the 1st generation 1G, 2G, 3G and 4G networks, 5G has become a new global wireless standard.
5G technology allows for the invention of a new type of network that connects virtually anyone and everything together.
Including computers and anything connected to the Internet, this network, and various smart devices.
The letter G in 5G indicates the generation of wireless technology.
There are three types of 5G-low-band, mid-band and high-band technology.
- 5G low-band low-band uses less than 2GHz frequencies. These are the cellular and television frequencies that have been around for a long time. Long-distance travel is possible with this network, but there are not many channels supporting it. And many of these channels are only used for the 4G network. As a result, the low-band 5G network is slow. For now, it looks like a 4G network. The width of the 5G low-band channels ranges from 5MHz to 15MHz.
- The frequency range of mid-band 5G is 2 to 10 GHz. This includes the majority of current cellular and Wi-Fi frequencies, as well as slightly higher frequencies. Because these networks have a reasonable range of their antennas, often around half a mile, they are called backbone networks that carry the majority of the 5G traffic in most other countries around the world.
- 5G high-band is mostly airwaves in the 20-100 GHz band. These frequencies have not been used for consumer purposes before. They have a short range, but there are a lot of unused signals in the previous lower quality and stronger bands, which means that they can operate at very high speeds, up to 800MHz at a time. This high-band transmission was used in the past to connect base stations with remote internet links. However, due to the lack of portable processing power and highly advanced antennas at that time, they were not used for consumer devices i.e. regular users.

How does 5G work
5G networks, like other cellular networks, use a system of cellular sites that divide their territory into zones and transmit encrypted data over radio waves.
Each cell site must be linked to the transmitter column of the network, whether by wired or wireless connection.
Since 5G networks handle more and smaller cells that can change their size and shape than previous systems, they should be much better than previous systems.
However, Qualcomm claims that 5G will be able to increase capacity by four times.
This compares with current systems by taking advantage of wider bandwidth and advanced antenna technologies, even with the presence of macro cells present in the receiving devices.
What about the networks of generation 1, 2, 3 and 4?
The 1G network was an analog cellular network.
The first wave of wireless cellular technology was 2G, which included GSM, CDMA, and TDMA.
3G technologies have brought speeds ranging from 200 kbps to several megabytes per second.
4G technologies, such as LTE and WiMAX, were the next incompatible step forward, with speeds reaching hundreds of megabytes and even gigabytes.
Now in 2021, the 1G and 2G technologies are gone.
Many mobile networks are planning to terminate service on their 3G networks by next year.
However, 4G has many years of life remaining in these networks.
Initially, all 5G networks relied on 4G to establish their links, a practice known as “non-standalone”.
We are trying to move away from this and toward “standalone” networks, but without the aid of 4G, 5G networks lose a lot of performance.
As a result, for a long time, most networks will be combined with 4G or 5G links.
