Why 5GHz frequency is preferred over 2.4GHz one?


Decades ago, when WiFi technology was introduced, there were only two versions you could choose from 802.11a and 802.11b. If we see from the perspective of a consumer, there was hardly any difference between the two. So in this article, we will explain you why 5GHz frequency is preferred over 2.4GHZ one. We will discuss about wireless range extender, wifi signal repeater and also about the best wireless range extender in the market. Keep going through the whole article to know deeply about the wireless radio signals.

Wireless Network Speed

There is a variety of wireless standards in which WiFi networking comes in. The below-mentioned series is an evolution of wireless standards with improvement in wireless technology.

  • 11a
  • 11b
  • 11g
  • 11n
  • 11ac

The above mentioned wireless standards are related to GHz wireless band frequency. So a 5GHz wireless radio signal carries more data than a 2.4 GHz wireless signal which makes it technically a faster wireless band for wireless networks. The 5GHz wireless band supports significantly higher data transmission rates in network standards like 802.11n and 802.11ac. Many of the modern wireless range extenders come with 5GHz wireless radio frequency band which sync better with your wireless router with the 5GHz wireless standard.

Network Range

As the wireless frequency goes higher, the wireless signal range goes down and hence resulting in low network range in 5GHz wireless networks. 5GHz wireless signals are unable to penetrate solid indoor walls which isolate the wireless network strength. But in the case of a 2.4GHz wireless network, wireless signals penetrate the indoor walls which result in higher signal strengths. As frequency is low in the 2.4GHz wireless network, data transmission rate is also low as compared to the 5GHz wireless network. You may need to use a wireless range extender or a WiFi signal repeater which will overcome this issue of low signal strength.


Routers with both wireless networks i.e. 2.4GHz and 5GHz are generally more expensive than the routers with 2.4GHz wireless network band. This also happens in the case of a wireless range extender or a WiFi signal repeater because wireless range extender with dual-band technology is more expensive than the signal band. Some of the people believe that 5GHZ wireless network technology is the latest and more innovative than 2.4GHZ. In fact, both of the technologies are proven and existing since long.

Advantages of a 5GHz wireless band

  1. The 5GHz wireless band comes with the noise reduction which improves the data transmission and avoids frequent network disconnections resulting in an enjoyable experience.
  2. Wireless signals from Bluetooth and other peripherals will not be able to interfere in your wireless network.

There are more reasons why a 5GHz wireless band is better with an 802.11ac wireless protocol. But we are here to discuss about 5GHz spectrum rather than 802.11ac specifically.

Bottom Line

5GHz and 2.4GHz are different wireless bands with different wireless frequencies. But both the wireless bands have advantages for wireless networks. So if you need a higher signal range at your home or office even if you have multiple indoor walls, 2.4GHz will work better for you. But if you need higher data speeds without these limitations, 5GHz will be a better choice. Nowadays, wireless devices come with dual-band technology which provide the best of both 2.4GHz and 5GHz wireless radios. This can be known as an emerging network solution for offices and homes.


So this article taught you why 5GHz frequency is preferred over 2.4GHz one. We discussed about the advantages of 5GHz wireless standard and in what cases you would need a wireless range extender or a WiFi signal repeater.
