Today, wireless devices are increasingly popular and very popular, especially wifi networks. When installing a wifi network in homes or businesses, you must have heard about 2.4GHz or 5GHz wifi. So what is GHz wifi? What is the frequency band? Find out now.

Learn about wifi and frequency band

People often wonder what is wifi gateway but forget the most basic concept that they are still vague about, which is about wifi. So what is wifi? 

Wifi is a wireless internet access system. This type of radio stands for the wireless wave and is similar to telephone, television, and radio waves. This is an indispensable connection tool on phones, laptops, and smartwatches…

The band is simply understood as the frequency range of electromagnetic waves used to receive and transmit communication signals between devices using wireless technology. 

So, you may have understood what is GHz in wifi? GHz wifi or more specifically 2.4GHz wifi is simply wireless radio waves using the 2.4GHz band and similarly, 5GHz is wifi using the 5GHz band.

Some information about 2.4GHz and 5GHz wifi 

If you are bored with regular wifi or too tired of wifi speed test, the new wifi technology below will definitely make you excited.

What is 2.4 GHz and 5GHz wifi? Wifi 2.4 GHz and 5 GHz are both bands, part of the wifi network, like different broadcast channels of television but broadcast the same program.

So what is a 2.4 GHz wifi? As mentioned above, 2.4GHz wifi is a wireless radio wave that uses the 2.4GHz band. In other words, this is a channel of wifi with a frequency band of 2.4 GHz.

Wifi 5 GHz is a wireless radio wave using the 5 GHz band or a channel of wifi with a signal frequency of 5 GHz.

Dual band wifi is a device that supports both 2.4GHz and 5GHz bands. The two wifi bands 2.4 GHz and 5 GHz can operate on two different frequencies, so they do not interfere with each other. 

Dual-band wifi includes many devices with current wifi connections such as modems, routers, PCs/laptops, smart TVs

The difference between 2.4GHz and 5GHz

After learning about what is 2.4 and 5 GHz wifi, surely the question in your mind will be what is the difference between 2.4 and 5GHz wifi. In fact, the biggest difference between these two bands is in speed:

  • What is the max speed of 2.4GHz wifi? Under ideal conditions, the 2.4GHz wifi will support speeds from 450Mbps to 600Mbps. 

  • The 5GHz band will support connection speeds of up to 1300Mbps, twice as much as the 2.4GHz band.

However, note that the maximum speed will depend on the wireless connection standard that the router supports, this standard can be one of the following standards: 802.11b, 802.11g, 802.11n, or 802.11ac.

2.4 or 5GHz is suitable for you? 

It is impossible to say exactly what wifi is better 2.4 or 5 because each has its own characteristics:

  • 2.4 GHz uses longer wave connections, as well as for traveling through walls and solid objects. Due to too many devices using the same 2.4GHz band, congestion may occur, leading to sudden disconnections and slower connection speeds. 

  • 5GHz band is commonly used to transmit more data. With the 5GHz band, congestion is less likely compared to the 2.4GHz band. However, the 5GHz band uses shortwaves, so it is less able to penetrate walls and solid objects and has a shorter effective range than the 2.4GHz band.

So, depending on different usage conditions, the answer to the question of what is better for wifi 2.4 or 5GHz will be different.
