Choosing the Right Channel Width for Your Wi-Fi Network This is where the topic of channel width gets interesting. There is significantly more spectrum available in this band, with each channel occupying its own 20 MHz non-overlapping slice. Now that we have that covered, let’s move the discussion over to 5 GHz. With its limited amount of available spectrum, it is highly recommended that only non-overlapping 20 MHz channels are used. Up to this point, we have only used the 2.4 GHz band for examples. This is caused by more devices trying to gain access to the wireless medium on the same channel, making STAs wait longer for their chance to transmit.Ģ.4 GHz CCI (Co-Channel Interference) Source: Ekahau ECSE Design Course While not as damaging as ACI, CCI will also degrade performance. This means that any STA that has anything to transmit now must wait for not only the other STAs associated to the same AP, but also all the STAs associated to the other AP on the same channel. This essentially turns both cells (a cell is the coverage area for an AP) into one big cell.

Source: Ekahau ECSE Design CourseĪdjacent Channel Interference. This type of interference is called Adjacent Channel Interference (ACI).Ģ.4GHz Channel Overlap. Think of it like being between radio stations and having a mix of country overlapping on your favorite metal station. When overlapping channels are used, any stations (STAs) on those channels will transmit independent of what is happening on the other channels, causing a degradation of performance. Put simply, only one device can successfully transmit at a time. Without getting too deep on how wireless communication happens, when a station (Access Point, client device, etc.) has something to transmit, it must wait for the channel to be clear. 2.4 GHz Channel Overlap & Adjacent Channel Interference 2.4 GHz Channel PlanningĮven though there are 11 channels available in 2.4 GHz in the US, only 3 of them do not “overlap” or interfere with one other: 1, 6, and 11. In the 5 GHz band, we have channels ranging from 36 up to 165, and in the 6 GHz band, we have Wi-Fi channels ranging from 1-233. In the United States, the 2.4 GHz band is broken up into 11 channels (1-11), each 20MHz wide. Depending on where you are in the world, you will have different amounts of channels that you can have access to with different rules and regulations. The IEEE 802.11 standard defines operation for wireless networks in both the 2.4 GHz, 5 GHz and now 6 GHz frequency ranges.
