  • 0

What is 5g Technology?

5G is the latest generation of mobile network technology, following 1G, 2G, 3G, and 4G. It brings significant advancements in wireless communication. 5G connects various devices, including machines, objects, and people’s devices.

It provides higher performance and efficiency, enabling new and improved user experiences and connecting various industries. The question of how much 5 G is raised in many people’s minds, then read below to get the answer.

How Does 5G Work? 

Wireless communication systems transmit information through radio frequencies or spectrums. 5G, like previous networks, uses radio frequencies but operates at higher frequencies called millimeter waves. These higher frequencies were unused before and have now been made available for licensing by regulators.

While higher frequencies enable faster data transmission, they have limitations over long distances, as objects like buildings and trees can easily block them. To overcome this, 5G will use multiple antennas to boost signals and improve network capacity.

Unlike traditional standalone masts, 5G will use more miniature transmitters placed on buildings and street furniture. This technology is expected to support a much larger number of devices per area than 4G.

One significant feature of 5G is its ability to divide a physical network into multiple virtual networks. It allows operators to deliver the appropriate network slice based on specific usage requirements. For example, different network slices can be allocated to a user streaming a video, a business, or simpler devices. It helps optimize network management and prioritize different types of applications.

Furthermore, there are plans to offer businesses the option to rent their dedicated network slice, separate from general internet traffic. It provides them with increased privacy and isolation from competing network activities.
