As 5G coverage expands across the globe, there are much more questions than answers. In this article, we will discuss everything about 5G technology. We will cover how the 5G network works, what happened to its predecessors 3G and 4G, and which are the best 5G phones for Android.

What is 5G?
5G refers to the fifth-generation mobile network. After its predecessors 1G, 2G, 3G, and 4G networks, 5G is a new global wireless standard. 5G allows for the innovation of a new type of network that connects practically anybody and everything, including computers, objects, and devices. The G in 5G refers to a wireless technology generation. There are three kinds of 5G-low-band, mid-band, and high-band.
Low-band 5G uses frequencies less than 2GHz. These are the cellular and television frequencies that have been around the longest. They can travel long distances, but there aren’t numerous channels available, and numerous of those channels are used for 4G. As a result, low-band 5G is sluggish. For now, it looks and sounds like 4G. Low-band 5G channels range in width from 5MHz to 15MHz.
The frequency range for mid-band 5G is 2–10GHz. That includes the majority of existing cellular and Wi-Fi frequencies, as well as frequencies slightly higher. because these networks have a sensible range from their antennas, typically about half a mile, they are the workhorse networks that carry the majority of 5G traffic in many other countries.
High-band 5G is mostly airwaves in the 20-100GHz range. These frequencies have never been used for consumer purposes before. They have a short-range, but there is a lot of unused spectrum up there, which implies they can run at very high speeds, up to 800MHz at a time. High-band backhaul has been used in the past to connect base stations to remote Internet links. However, because handheld processing power and highly advanced antennas were not available at the time, they were not used for consumer devices.
How 5G Works?
5G networks, like other cellular networks, use a system of cell sites that divide their territory into areas and transmit encoded data through radio waves. Every cell site should be linked to the network backbone, whether by wired or wireless backhaul. because 5G networks are dealing with numerous much more and smaller cells that can change 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 over current systems by leveraging larger bandwidths and advanced antenna technologies, even with existing macro cells.
What about 1G,2G.3G, and 4G?
1G was analog cellular. The first wave of wireless cellular technology was 2G, which included GSM, CDMA, and TDMA. 3G technologies brought speeds ranging from 200kbps to several megabits per second. 4G technologies, such as LTE and WiMAX, were the next incompatible step forward, with speeds reaching hundreds of megabits and even gigabits. now in 2021, 1G and 2G technologies are gone. AT&T is planning to end service on their 3G networks in February 2022. 4G, however, has numerous years of life left. 4G networks and coverage are needed for all 5G phones. Initially, all 5G networks relied on 4G to create their links, a practice known as “non-standalone.” We’re moving away from that and toward “standalone” networks, but without the help of 4G, 5G networks lose a lot of performance. As a result, for a long time, many networks will be combined 4G/5G links.
Where Is 5G Available?
5G is currently available in numerous major cities across the globe.
In the United States, 5G service is provided by all four major carriers (AT&T, Verizon, T-Mobile, and Sprint) in select markets. In Europe, 5G service is live in numerous countries including the UK, Germany, Italy, and Spain. Asia also has numerous 5G networks up and running in countries like South Korea, China, and Japan. Australia also has several 5G networks operational.
Is 5G Safe?
The jury is still out on whether or not 5G is safe. Some experts say that 5G is safe, while others say that much more research is needed to identify the long-term effects of 5G radiation on human health.
What we do know is that 5G technology uses higher frequency waves than previous generations of wireless technology. These higher frequency waves have shorter wavelengths and can carry much more data. However, they also Penetrate the human body much more deeply than lower frequency waves.
This implies that 5G radiation can potentially have a greater impact on human health than previous generations of wireless technology. So far, there is no scientific evidence to suggest that 5G is risky for human health. However, much more research is needed to confirm the safety of 5G.
