Interference: The number of channels available in each band varies according to the country in which the WiFi station operates.Under ideal conditions, and therefore without interference, the 2.4GHz band supports speeds between 450Mbps and 600Mbps while the 5GHz band supports speeds up to 1300Mbps.
For this, the 5GHz band offers a higher data rate.
Transmission speed: The 5GHz band operates on higher frequencies and is able to transfer, compared to the 2.4GHz band, more information in the same time unit. 2.4GHz capable devices are very often referred to as “3 room devices” while 5GHz capable devices are known as “2 room devices”. For this reason, signals transmitted on the 2.4GHz band tend to penetrate solid objects more easily and therefore offer greater coverage. 
Signal coverage: The 2.4GHz band operates on lower frequencies than the 5GHz band, and consequently the wavelength of a 2.4GHz signal is greater than that of a 5GHz signal. There are many differences between these two bands, but we can identify the main ones: That said, how do these two bandwidths differ and which is the best? And more importantly, how can you identify which is the best communication channel of each of these bands, so that you can properly configure your router or WiFi access points to experience a fast and stable Wireless communication? How are 2.4GHz and 5GHz bands different?īefore identifying which channel is best to set up your router or WiFi access point, you need to decide which of these two bands to use. While the 2.4GHz band is older and supported by all routers, the majority of the recently produced WiFi stations moved from the single band support (2.4GHz only) to dual-band support (2.4GHz + 5GHz). 
The WiFi 802.11 standard specifies different frequency ranges that can be used for WiFi communications, but in most cases only two of these are used by common routers: the 2.4GHz and the 5GHz bands. What are WiFi channels?Ī WiFi channel is a small portion of bandwidth that identifies a range of frequencies used by a router or a WiFi access point to transmit wireless signals. However, sometimes the problem needs a more advanced configuration of your network and, to be more precise, of the WiFi communication channels. Most times, connection problems are solved by moving the device closer to a WiFi access point or by adding other WiFi stations to your setup. Usually, it is common to blame the internet provider for these kinds of issues, but very often the problem lies in the setup of your WiFi connection.
