2.4 GHz vs 5 GHz – In this article we going to talk about the WiFi Routers types when you go in the market or search online for the WiFi Router. You’ll notice there is 2 types of router first one is 2.4 GHz and the second is the latest WiFi router 5 GHz. Many people gets confuse which WiFi router is best for them.

2.4 GHz vs 5 GHz WiFi What is the Differences?
A frequency band is how wireless data is transmitted between devices. These tapes are radio waves that carry the data and these tapes are 2.4 gigahertz or 5 gigahertz. Now many Wi-Fi routers will only transmit send one of these bands, which is the 2.4 band and that is because it is the most common frequency and it is called single group routers.
But many of newer Wi-Fi routers will have both the 2.4 and 5 gigahertz bands would be transmitted and these are called dual-band Wi-Fi routers. Now the 2.4 band works pretty well. This is the standard band. But the problem is that it is not just a standard band used in Wi-Fi routers.
It is also the standard band that in many other devices, such as microwaves, cordless phones, Bluetooth devices and wireless cameras, all used a 2.4 gigahertz band and this has become a problem. Because the fact that so many other devices Using 2.4 band, the signal becomes overcrowded and causes a lot of interference with Wi-Fi signals.
And when it does, it slows down the Wi-Fi network speed and can sometimes cause you to disconnect from the Wi-Fi router lost, therefore the 5 gigahertz band the 5 gigahertz was added. 5GHz band is a newer band and so it is not as commonly used as the 2.4, so it is used by fewer devices.
And because it is used by fewer devices, is the 5 gigahertz not so busy. Thus, there is no interference or minimal interference. So using the 5 gigahertz can alleviate the problem associated with slow network speeds and drop in connections caused by interference from other devices.
2.4 GHz vs 5 GHz Wireless Channels
Another reason why the 2.4 is more vulnerable to interference is due to the difference in wireless channels. If you are now unfamiliar with what a wireless channel is, a wireless channel is just a way to adjust a frequency and change the frequency. Sometimes you may need to switch to a different channel if you experience interference from different wireless devices and switching to a different channel will give you the capability.
The 2.4 gigahertz band has 11 channels to choose from, but out of these 11 channels, only 3 are non-overlapping. You basically have three fixed channels to choose from. But the 5 gigahertz has more channels. It has 25 non-overlapping channels.
2.4 GHz vs 5 GHz Speed and Range
And some other differences between a 2.4 and 5 gigahertz band are its speed and range. The 2.4 gigahertz band sends data at a slower speed than the 5 gigahertz, but it has reached a longer time than the 5 gigahertz. The 5 gigahertz band sends out data at a faster speed than a 2.4, but it has a shorter range.
The 5 gigahertz has a shorter range because it has a higher frequency and that higher frequencies are more difficult to penetrate solid objects, such as floors and walls in a building.
As you can see from this illustration, this dual-band Wi-Fi router transmits a 2.4 gigahertz band, which has the color green, and it also emits a 5 gigahertz band, which has the color red. As you can see, the 2.4 band has a longer range and can cover the signal most of this building and It can also penetrate the second floor and the walls.
But the 5 gigahertz band has a shorter range. The signal does not penetrate to the second floor or the walls that limit the range in a building. The question then is which band do you actually want to use? And it really depends on your situation.
2.4 GHz vs 5 GHz Pros and Cons
They both have their pros and cons. The advantage of a 2.4 gigahertz is that it has a larger range and that it can penetrate better into solid objects. But the disadvantage is that it is more vulnerable to interference because so many other devices use the same band and it is also slower than the 5 gigahertz.
2.4 gigahertz is probably the most widely used one because it was basically out first and a lot of small devices like Bluetooth, devices phones, garage door, Openers even little baby monitors operate. On this wavelength so it can be a bit overcrowded at times which is why there are some benefits from switching over to the 5 gigahertz length.
And the advantage of the 5 gigahertz is that it ‘ has a higher transmission speed and that it is less vulnerable to interference, but at the same time it has a shorter range and is more difficult to penetrate through fixed objects.
5 gigahertz signal can kind of alleviate some of this congestion if you’re having trouble with a spotty connection. So what does this mean for performance well five gigahertz can offer you some faster speeds, but its kind of depends on the scenario.
Say you’re in a bigger home two three stories you might want to stick with a 2.4 band because that way your signal strength will be higher and your speeds won’t be limited to where if you have a low signal strength on the five gigahertz band.
You might have potential for faster speeds but due to the low signal strength you’re never going to reach those. So if You’ve been clicking five gigahertz this whole time and not even wondering what the 2.4 is thinking a little slower, go ahead and switch over to that one real quick and see maybe you’re getting a better signal strength that way. And getting actually faster speeds on your phone or laptop or wherever you might be connecting to.
