What is 5 GHz Network? List of Devices Compatible with 5 GHz Network

Jul. 4, 2018

We all use WiFi at our homes and offices and most of us are familiar with the moniker 2.4 GHz and 5 GHz frequency bands. In fact, all the connected devices that we buy today including our smartphones, tablets, and more, mention as to which frequency bands they support. That said, not many people know the difference between these frequency bands and that has led to a lot of confusion. Well, we will try to eradicate that confusion in this article as we explain everything that you need to know about the 5 GHz network to see what makes it different from the 2.4 GHz and is it any better:

Understanding WiFi

Both the 5 GHz network and the 2.4 GHz network come with their own pros and cons. Depending on the circumstances, sometimes using the 2.4 GHz network will be beneficial for you and vice versa. That said,in general using the 5 GHz network will yield a faster network speed, however, not for the reasons you might think. People who don’t know about the network transfer protocols might assume that the speed on 5 GHz network will be faster as it has a higher frequency, however, that cannot be farther from the truth.

Due to the above two reasons, the 2.4 GHz band suffers a lot of interference.The impact of this interference can cause anything between lower data speeds to a complete signal lossdepending on the nature and severity of interference. I don’t want to bore you with the technical stuff, so the thing that you should know is that RF channels are a shared medium. So, all the devices using the same channel as your access point will be using the same bandwidth. Seeing how 2.4 GHz network is the used by almost every smart device, that bandwidth is low to begin with. Add that to the fact that in the 2.4 GHz band, the channels overlap with each other, which causes the devices which are not even in your channel to use the same bandwidth which in turn also impedes your network.

The problems that you experience while using a 2.4 GHz network doesn’t exist in the 5 GHz network, as it’s not used as much as the former.This means that 5 GHz network still has a lot of free bandwidth which is not being exploited. It also helps that channel width in 5 GHz network is 20 MHz, and hence, none of the channels overlap with each other. Because of these two reasons, the 5 GHz network is not prone to the problems faced by the 2.4 GHz network.

Although the 5 GHz network doesn’t suffer from the same problems that we have discussed till now, it has its own fair share of problems. The biggest problem of using a 5 GHz network is thatit cannot travel far and is easily impeded by structures such as walls, doors, and other physical hurdles around it. What that means is that for getting the best speed possible, you should be direct in the line-of-sight of your router. That’s why if you are using a single router in your home, and your room doesn’t have its own router, the signal that you receive in your room will be far weaker on a 5 GHz network than what you would get if you are using the 2.4 GHz network.Courtesy:VeEX Inc.

As you can see, although 5 GHz network suffers from a few problems itself, its pros far outweigh its cons. If you want your devices to get the best internet speed in the future, you should only buy the ones which support 5 GHz WiFi Network. We have attached the list of all the phones released in the past two years which support 5 GHz WiFi Network to help you find out if your device supports it or not:

5 GHz WiFi network is nothing new. In fact, it was ratified in the September of 1999 along with the 2.4 GHz network. That said, since the deployment of 2.4 GHz network was easier and cost-effective, it quickly became the universally adopted WiFi network while the 5 GHz band took a backseat. Now that the 2.4 GHz frequency band is overused and is causing a lot of connection problems, people are turning towards the 5 GHz network which has been sitting empty for almost two decades. To conclude, the 5 GHz network is nothing revolutionary, however, it is something that we need to adopt if we are to solve our WiFi connectivity problems.

I hope that I was able to explain the 5 GHz WiFi network in a way that was understandable.  Do keep in mind that I  have simplified some of the technical topics to make this article more reader friendly.  If you still cannot grasp this or have any doubts, ask your questions in the comments section below and I will try my best to answer them as soon as possible.
