2,4 GHz or 5 GHz Wi-Fi is better? If you have already chosen the Provider and therefore a subscription to surf the Internet but you are undecided whether to buy a router that supports the 5 GHz band or the 2,4 GHz band, then you absolutely must read this guide because I will reveal to you which is the best band to use. to connect to the Internet.

Theoretically, the two bands have their pros and cons and can be used depending on the type of use you will make of the connected devices.



Above all, we must understand that choosing a wireless router that supports a 2,4 GHz band or a 5 GHz band will not change the browsing speed, indeed it will remain the same, as the transfer speed will still be considerable. So the question to ask is what is the difference between the 2,4 GHz Wifi network and the 5 GHz Wifi network?

The first step you will have to take is to make sure that there are no obstacles inside the house: large walls, partitions and so on, and that the layout of the rooms is regular.

You will then need to set the router to 5 GHz and check if the reception anywhere in the house is optimal. It is essential that there are no other wireless sources nearby and that the device is not too close to a microwave oven or similar. The 5 GHz band transmits a greater amount of data and in addition to being wider it allows any type of transmission through 23 channels that do not interfere with each other. It is higher than the 2,4 GHz band but is heavily affected by surrounding interference and obstacles.


On the other hand the 2,4 GHz band overcomes obstacles better and has an almost total but tighter coverage. It is also affected when the devices connected at the same time become several. There are 13 channels, but being too close to each other, only those 1, 6 and 11 manage not to overlap.


In conclusion, the difference between 5 GHz and 2,4 GHz Wifi is that:

La 5 GHz band, has solved the problem of crowding wireless networks, and is recommended in case wireless devices are used for large file transfers within the home network or need to access media files for real-time streaming, (such as NAS or networked hard drive) of high-definition movies or videos. Attention if you use a Wifi card b / g / n that does not support the "a" standard you may not be able to transmit data on the 5 GHz band. The WiFi standards "a" (5 GHz) and "n" (2,4 GHz / 5 GHz) are capable of transmitting data in the 5 GHz band.


La 2,4 GHz band it is recommended for large apartments where signal coverage is perfect. In this case the wireless card will need to be 802.11n.


A dual band Wifi or wireless router will allow you to have both the 5 GHz and the 2,4 GHz network available, as they allow you to configure the two wireless networks on different frequency spectra.
