5G and 5GHz Wi-Fi are both used for wireless connections, but they have nothing else in common. Anyone who refers to "5G Wi-Fi" actually means 5 GHz Wi-Fi, which is different from the 5G wireless standard.
5G is the new mobile standard
You will soon hear more about 5G. It is a mobile standard and is the successor of 4G LTE and 3G. 5G stands for the "fifth generation" because it is the fifth generation of this mobile standard.
5G is designed to be much faster with lower latency than 4G LTE. They will see the first 5G smartphones in 2019, and mobile operators such as AT & T, T-Mobile, Sprint and Verizon will launch their 5G mobile networks. 5G could convert your Internet connection at home by also providing a fast broadband internet service wirelessly.
5G is an exciting new standard but has nothing to do with Wi-Fi. 5G is used for cellular connections. Future smartphones may support 5G and 5 GHz Wi-Fi, but current smartphones support 4G LTE and 5 GHz Wi-Fi.

5GHz is one of two bands for Wi-Fi
Wi-Fi has two frequency bands that you can use: 2.4GHz and 5GHz. 5 GHz is the newer. It was widely used with the 802.11n Wi-Fi standard, which was originally released in 2009. It's still part of modern Wi-Fi standards like 802.11ac and Wi-Fi 6.
5 GHz Wi-Fi is great. It provides more non-overlapping channels, which makes it less congested. It is great for places with lots of Wi-Fi congestion, such as apartment buildings, where each apartment has its own router and WiFi. 5GHz Wi-Fi is also faster than 2.4GHz Wi-Fi.
Despite these slower speeds and increasing congestion, the 2.4 GHz Wi-Fi still has its advantages. 2.4GHz covers a range larger than 5GHz and is better able to walk through walls thanks to its longer radio waves. These shorter 5 GHz radio waves provide a faster connection, but they can not cover so much ground.
If you even have a relatively modern router, it's probably a dual-band router that supports both 5 GHz and 2.4 GHz Wi -Fi at the same time.
We've seen people use the term "5G Wi-Fi" to refer to 5GHz Wi-Fi, but that's wrong. They mean "5 GHz Wi-Fi".

Why some Wi-Fi networks? Say you are "5G"?
To make things a little more confusing, people sometimes call their networks things like "My Network" and "My Network – 5G". That's pretty misleading, but it was not too confusing before 5G came. Here is "5G" only an abbreviation for "5 GHz".
This is because wireless routers that support 5 GHz wireless LAN can be configured in several ways. These routers can simultaneously host a 2.4 GHz and a 5 GHz network, which is useful for older devices that only support 2.4 GHz, or larger areas that have devices that are outside the 5 GHz range but still in the 2.4 GHz range.
If the same name is assigned to both Wi-Fi networks (for example, for your 2.4GHz and 5GHz networks "My Network"), any connected smartphone, laptop, or other device will automatically go between networks switched. Select 5GHz network and access the 2.4GHz network when needed. That's the goal anyway. In reality, many devices do not do this properly and they can only connect to the 2.4GHz network or try to connect to the 5GHz network and fail.
Because of this, the configuration of routers for two separate Wi-Fi devices is often set -Fi network names. You could call something like "My Network – 2.4 GHz" and another like "My Network – 5 GHz". Both are hosted by the same router, but one is 2.4GHz and one is 5GHz. You can then choose which network you want to connect to on your devices. Of course you do not have to use descriptive names like these – you could call a "lime" and a "lemon" if you wanted
Why do people say "5G Wi-Fi"?
5G is a fairly new standard. Some people called 5GHz Wi-Fi "5G Wi-Fi" in the days when 3G and 4G LTE were the prevailing wireless standards.
It was never officially named, but it was a shorter name that some people used. It's like many people called the iPod Touch "iTouch". That was not the official name, but everyone knew what he was talking about.
But now that 5G is about to launch in consumer devices, "5G Wi-Fi" is just confusing and unclear. If you connect the term "5G" to Wi-Fi, this probably only applies to 5 GHz Wi-Fi.
In most cases, however, "5G" refers to the new mobile standard. Hopefully, as 5G spreads, people should be more precise to avoid confusion.
