What Should You Know About 5G Technology?
Wireless carriers around the world are beginning to deploy 5G, the latest and greatest in mobile broadband technology. Like the evolution from 3G to 4G, the jump to 5G will mean faster speeds, lower latency and many other benefits.

What is 5G?

The so-called 5G refers to the fifth-generation network of mobile communication networks. Compared with the previous four-generation mobile networks, the 5G shows more functions in the actual application process. It can transmit data much more quickly than 4G, which many of us use to connect to the Internet today. But it also requires towns and cities to set up a much higher number of small cells, or short-range transmitters, to provide the same geographic coverage as 4G.

How does 5G work?

Unlike 4G, which requires large, high-power cell towers to radiate signals over longer distances, 5G wireless signals are transmitted through large numbers of small cell stations located in places like light poles or building roofs. The use of multiple small cells is necessary because the millimeter wave spectrum-the band of spectrum between 30 and 300 gigahertz that 5G relies on to generate high speeds-can only travel over short distances and is subject to interference from weather and physical obstacles, like buildings or trees.

How fast is 5G?

5G download speeds can currently reach upwards of 1,000 megabits per second (Mbps) or even up to 2.1 Gbps. To visualize this, a user could start a YouTube video in 1080p quality on a 5G device without it buffering. Downloading an app or an episode of a Netflix show, which may currently take up to a few minutes, can be completed in just a few seconds.

What are the benefits of 5G?

Even though the downsides of 5G are clear when considering how easily mmWave can be blocked, or less clear considering radio frequency (RF) exposure limits, 5G still has plenty of worthy benefits, such as the following:
5G technology has fast transmission speed.
5G technology has steady transmission.
5G technology has high-frequency transmission..

What’s the challenge 5G face now?

In terms of implementation, 5G technology still faces huge challenges. Building 5G-enabled infrastructure requires significant capital investment. 5G cannot be powered by the mechanisms of 4G-LTE, so existing base stations will need to be overhauled and smaller, cooler towers need to be built.
In terms of security, 5G has inherent fragility characteristics of virtual networks. So in practical applications, it is more likely to be attacked and stolen than physical communication. There are also higher requirements and standards in terms of security and information security. Therefore, 5G technology will inevitably face security challenges in practical applications in the future.
The emergence of each generation of emerging communication systems has profoundly affected our society and life style. 2G changed the way people communicate and 3G promoted the Internet industry’ migration from the PC side to the mobile side. 4G brings a better user experience, and 5G will definitely affect our society more thoroughly.
