2.4 Ghz or 5 Ghz? Which is better?




Wi-Fi technology is based on one of the 2.4, 5 or 60GHz radio frequencies to establish connections between different devices.

Almost any Wi-Fi device that you will encounter connects to a wireless router via the 2.4GHz band. There is also the 5GHz band, and the devices that offer this functionality also work in double band.


The 5GHz band offers higher speeds than 2.4GHz because it includes a larger number of channels, 23, compared to the three lower band.


The difference between Wi-Fi bands: range

An antenna connected to the router emits radio waves in a spherical shape. Range of action is the ideal radial distance covered by transmitted waves, starting from the center of the sphere.


The 5GHz band is faster but has a smaller range. This is because higher frequency radio waves go harder through walls or other large objects. A WiFi-G router has a range of about 70 meters, while a WiFi-AC type is only halfway, 35 meters.


Wi-Fi-AD: 60GHz


Once WiFi-AD has boosted using the IEEE 802.11ad standard, the 60GHz band has begun to be used on Wi-Fi networks. At this frequency, compatible devices can achieve data transfer speeds of up to 8Gbps, with a range of 60 meters.
