In today’s life, wireless devices are increasingly popular, especially wifi networks. This is an indispensable part of the booming information technology era.
Wifi is a familiar phrase to everyone; however, when installing wifi networks in homes or businesses, you must also hear about 5GHz wifi and wondering what it might be?
So, today, in this article, we will walk you through all things you need to know about 5Ghz wifi and which is the best channel for 5Ghz.
Let’s dive right in!
What is 5ghz Band
Band is simply the frequency range of electromagnetic waves used to receive and transmit communication signals between devices using wireless technology. Thus, you can understand 5Ghz wifi as a wireless radio wave (Wifi) using the 5GHz band.
5GHz band technology has the same concept and how it works like traditional 2.4GHz technology, but it possesses OFDM technology throughout the transmission network speed range.
Also, it comes with a Multiple Input-Multiple Output, also known as MIMO antenna that supports intelligent multi-connection and higher performance.
Devices connected to a wifi network can transmit data over a defined frequency range through 5GHz and 2.4GHz type of routers. In particular, 5GHz wifi is faster than 2.4GHz because they operate at higher frequencies. Under ideal conditions, 5Ghz wifi can deliver data rates up to 1300 Mbps, twice as fast as the 530 Mbps maximum of 2.4 GHz networks.
5Ghz wifi has widely used standards like 802.11a. This was a 1999 standard that promised to bring network connections to devices. It was delivered over the air instead of over copper cables.
As the first wifi protocol, it was built around the 5GHz frequency band but didn’t gain much appeal in the consumer market due to its relatively expensive price tag.
After that, the technology world continued to introduce the 802.11n standard in 2009 with the ability to transfer data up to 600mbps.
The biggest breakthrough in 5Ghz wifi standards was the advent of 802.11 ac in 2014. This standard increases communication speed between wireless devices by twice as much compared with the old standards, reaching a record 1Gbps.
Which is The Best Channel For 5ghz?
If you set up your router at 5GHz, you’ll find that there are quite a few channels to choose from. With more channels and higher frequencies, the bandwidth level will increase to 5MHz per channel.
Technically, when you raise the frequency, that means more data is carried around in a short time.
Wifi 5Ghz will have four bands; each band will contain many different channels. These channels will be numbered from 36 to 181. However, these numbers are not in succession, but there will be hops of about 4.5 characters between them.
These wifi channels are served in the home and for many other purposes such as corporate environments or scientific research.
High-frequency channels, such as the 165, are often used in military or government barracks. Therefore, when you expand the bandwidth connection, there is a possibility that you will have network congestion because of violating the limit of frequency 165.
It would be best to stick with a frequency around 36 to 48. Any number within between should be working for you. Before connecting, you need to choose the best channel for 5Ghz frequency.
The first way you can do it is to use the Dynamic Frequency Selection (DFS) system. As its name implies, this system will help you find the most appropriate channel for the frequency band, based on surrounding physical conditions to avoid congestion. Besides, using channel selectivity is a great way to eliminate channel overlap.
Another simpler way is to install the application on your phone. There are a lot of apps out there for you to do this. They will rely on your antenna and the GPS on your cell phone to calculate and find the best option.
Remember that when using the application, you need to choose the exact 5Ghz frequency band. Otherwise, the data may have significantly deviated.
Besides, if you are using some older phone models that still operate at lower frequencies or channels, it may also cause interference with the channel selection process.
In that unfortunate case, you can manually tune the channel. Please connect your router to each wifi channel one by one. If there are so many people available on the same channel as you, your devices will automatically change to different frequencies. However, this will be time-consuming and not recommended.

What Are The Benefits Of The 5ghz Channel?
One huge advantage of 5GHz wifi routers is their ability not to interfere with other wireless transmitters.
Devices used in the home or office, such as phones, often use the 1.9 GHz band, while devices such as Bluetooth, warning systems, or wireless speakers, etc., using radio waves can weaken the wifi network.
5GHz wifi waves are completely unaffected by this lower frequency range as they provide more channels and have a wider range. Therefore, giving you a more stable wifi connection.
If you use 5Ghz wifi technology compared to old technology in the same environmental conditions, the 5Ghz wave will go a lot further. This opens up future opportunities for telecom service providers, helping to transfer data further in difficult environments without spending too much time.
Wifi is susceptible to interference by nearby wireless networks. Currently, broadcast routers mainly operate at 2.4GHz. 2.4GHz wifi transmitters can be installed on 11 different channels. However, only three of them (channel 1, 6 and 11) can be used concurrently without overlapping.
The 5GHz network completely overcomes this overlap problem because it uses frequency band from 5.1 to 5.8GHz, which is a lot wider than 2.4 GHz router. The 5GHz band has between 8 and 23 channels (depends on the setup and whether double-wide channels are used) available for you to use.

Because of the fast transmission speed and very wide coverage, the trend of developing a 5Ghz network in the future will explode around the world.
In addition, the efficient exploitation of the 5Ghz system will change the speed of technology development, especially when there are more connected devices that have not been previously exploited.
We hope that you are now equipped with enough information to determine which is the best channel for 5Ghz. Thank you for reading.
