In this article we will deal with which channel WiFi to choose from 13 available so that you have the best Results and we will analyze if the larger channels have better performance due to higher frequency.
A few days ago we had you suggests some technical solutions to increase its speed WiFi your. An important step in that article was to change the broadcast channel from wireless router your. In other words, we suggested that you turn off the automatic broadcast channel selection and set up a channel of your choice.
But the routers have 13 channels (and some have 14). The choice is to find a channel with the least traffic. If you're wondering that since you have two or more free channels which one to choose, let's look at it more thoroughly.
Each channel from 1 to 13 transmits to a central frequency that is spaced 5MHz with the next channel. However, each channel except the center frequency also has a bandwidth with 22MHz amplitude. It is easy to conclude that one channel overlaps the other by sending interference.
The following graph will show the channel frequency range and you will see that the 1 channel has a central frequency of 2.412MHz, the 2 channel has a central frequency of 2.417MHz, etc. We repeat that the 14 channel does not exist on all routers and even in some countries it is illegal its use as its frequency is used for military purposes.
You will see that although the higher channels have a higher frequency, their difference is so small that it can be considered negligible. It is like saying that FM stations closer to the right frequency band, ie close to 108MHz, are more remote and clear than 88MHz. The difference is really negligible and you should not give it meaning. Elsewhere you need to focus.
You should find a channel that not only has the least traffic but also the least overlap from the others. The automatic selection that routers make in priority are channels 1, 6 and 11. The reason is that these three channels, as you will see in the graph above, do not overlap with each other and therefore do not send interference to each other. Unfortunately, when your router checks to see which "empty channels" are, it only checks the space that is placed and does not take into account the 2nd and 3rd channels at all.eyea further that maybe you are interested in having a good signal.
So when you do a frequency analysis of all areas of your home and find at least two or three channels that are less busy, then choose the one that has the least interference from its neighbors. Only then will you have found a "clean" channel without traffic but also without interference.
