The terms 2.4 GHz and 5 GHz refer to 2 different radio wavelengths, which are known as “frequencies” “bands,” which are presently utilized by most routers (to transmit Wi-Fi connections).
At 2.4 GHz, a wireless transmission provides the net to a more significant area yet can’t give the fast internet speed, whereas 5 GHz gives fast speeds; however, it bounds itself to a smaller area.
We must note that each router is made to give a particular set of frequencies.
One shall require to consider which Wi-Fi channel & band provides the optimum performance to the user, & which shall best suit the user’s requirements.
It is to be noted that the range of the 5 GHz is relatively less than that of the 2.4 GHz frequency band. The frequency band of 2.4 GHz gives coverage at a more prominent area & has a more excellent range compared to the frequency of 5 GHz.
The difference that is seen in the range is just because a frequency band of 5 GHz has a greater frequency. Thus, it can’t get through the substantial items, which can be concrete walls, whereas the frequency band of 2.4 GHz may get through the articles and thus has a more excellent range.
This is another significant part that one has to note while checking out the differences, which is the signals’ interference.
The number of channels that a frequency band may carry is the point on which the interference depends upon.
In the case of the 2.4 GHz frequency band, there are mere 11 channels present.
As many gadgets and users utilize this frequency band, one may have to use the same channels & cause overcrowding. And this is how the signals interfere with one another, creating latency (high) in the internet speeds.
Yet, in the case of the 5 GHz frequency band, there are 23 channels available. As only a low count of electronic devices utilize this band, there is lesser interference & less traffic crowd, causing internet speeds (high).
3. Speed of Data Transmission
Here, the range of the frequency band of 2.4 GHz is more extensive than the band of 5 GHz, yet the band of 5 GHz may send data at a much greater speed than the band of 2.4 GHz.
It is seen that the rate of data transmission enhances when the frequency increases, & thus 5 GHz bands end data at more incredible speeds when compared to 2.4 GHz bands.
The frequency bands of both are rare in their ways: The frequency band of 2.4 GHz gives coverage at a more excellent range, yet there is a slow data transmission speed. The band of 5 GHz provides coverage at a smaller range; however, there is faster data transmission.
The Wi-Fi connection can be faster or slower on either of these frequency bands. By default, many wireless and Wi-Fi devices utilize the frequency band of 2.4 GHz & this contains almost every wireless gadget.
One can get the lesser speeds on a band of 2.4 GHz when various gadgets utilize a similar radio frequency, which causes overcrowding.
The band of 5 GHz may typically have no overcrowding as only a few gadgets utilize it. Hence, one may get much greater speeds on the 5 GHz band as compared to 2.4 GHz.
But if one requires range, then 2.4 GHz is the suitable option, and one must get the band of 5 GHz, while one needs faster data transmission.
Difference b/w Dual- & Tri-Band Routers?
Many new routers act as dual- or tri-band routers, which is good news to start with.
A dual-band router is the one that broadcasts a 2.4 GHz as well as a 5 GHz signal. It usually comes from a similar unit, providing one with Wi-Fi networks, i.e., two.
The Two types of Dual-Band routers are:
- Simultaneous dual-band.
A dual-brand router, which is concurrent, broadcasts by distinguishing 2.4 GHz and 5 GHz Wi-Fi networks simultaneously, providing one 2 Wi-Fi networks that one may select from when one sets up a gadget.
Few router brands also let one provide a similar SSID to 2 two bands so that gadgets only look at a single network—even though both are in use.
These are a bit more costly than selectable dual-band routers, but not with a more considerable margin. The merit of getting both bands operating at the same time outshines the difference in cost typically.
- Selectable dual-band
A selectable dual-band router gives a 2.4 GHz and 5 GHz Wi-Fi network, but one simultaneously utilizes one. One may have to use a switch to get the band one wants to operate.
Suppose one has many gadgets that generally utilize a 5 GHz connection heavily, such as watching 4K video or streaming high-resolution. In that case, one may take advantage of surfing a little more on a tri-band router.
A router of tri-band broadcasts one 2.4 GHz signal & two 5 GHz signals, i.e., three networks at the same time. The reason for this is to aid enhance the congestion of the network.
Which frequency band should you use?
Is 5GHz better than 2.5 GHz?…2.4 GHz and 5 GHz, both of the frequency bands, have their own merits and demerits.
So, the confusion becomes a necessity here.
Well, here are a few questions which we attempted to answer for you.
- Is the Wi-Fi network being shared with others or not?
Here, if the wireless network is to be shared with neighbors or on various floors of a building, one must select 2.4 GHz without a doubt as it has the strength to cover a more comprehensive range & go through floors & walls.
But, if only your flatmate or you are required to utilize the Wi-Fi network, then, without a doubt, one shall choose 5 GHz, frequency bands.
2. Is it the speed or the coverage that is required more?
Is 2.4 GHz fast?…..If you require low coverage & keen to have high internet speed, then 5 GHz must be the choice you opt for.
If one requires the coverage Wi-Fi signal to be larger even if the net speed decreases by some amount, one must choose the 2.4 GHz frequency band.
Check if the router supports the 5 GHz frequency band or not.
One must get if the router supports the 5 GHz band before choosing the best frequency band for its usage.
Most of the Wi-Fi routers used by customers usually include old models & cheaper ones, supporting only one frequency band, i.e., 2.4 GHz. One has got no other alternative then.
But, if the router supports dual bands & is of newer models, one shall notice 2 Radios. Each radio must work on frequency bands, which are 2.4 GHz and 5 GHz separately.
Or, one may get the technical details of the model of Wi-Fi router one is utilizing or which one requires to upgrade to.
When the details include the wireless standards such as 802.11ac or 802.11a, it indeed supports 5 GHz, while it shall not if the standards are 802.11b/g/n. Yet, the standard 802.11n may have the choice to support 5 GHz too.
