2.4 GHz vs 5 GHz: Popularity, interference, throughput, and rangeĢ.4 GHz is more popular than 5 GHz at the moment, but both are widely used. Note that this is a generalization and available channels vary depending on location and channel size. Using 20 MHz, there are 24 non-overlapping channels available within the 5 GHz band. However, an additional range of Unlicensed National Information Infrastructure (UNII) bands widens that range to 750 MHz. The 5 GHz Wi-Fi band covers a 150 MHz range from 5.725 GHz to 5.875 GHz. For example, only 11 channels are available in the United States. Note that due to varying regulations, not all channels are available for use in all locations. With 2.4 GHz Wi-Fi, there are four non-overlapping 20 MHz channels: 1, 6, 11, and 14. This is important to understand because overlapping Wi-Fi channels can interfere with one another. This is greater than the 100 MHz size of the 2.4 GHz band, which means that channels overlap. If you do the math, you'll quickly see that 14 bands of 20 MHz equals 180 Mhz. Note that channels 1, 6, 11, and 14 do not overlap. Note in the image above that there are 14 channels in the 2.4 GHz band. With 5 GHz, if you don't have to worry about interference and all your client devices support it, go with the highest width available.įor a practical example of how to optimize Wi-Fi, check out how CBT Nuggets trainer Keith Barker uses NetSpot and SweetSpots to examine channels for potential interference, map his coverage, and improve his home wireless network in this video: Conversely, with 5 GHz, increasing channel width can improve performance, but there are tradeoffs. With 2.4 GHz, increasing your channel width often isn't worth it, and you should stick with 20 MHz. With multiple standards and a variety of tradeoffs, it can be hard to keep up with best practices.Įvery wireless environment is different and you need to tailor your equipment to the conditions. Getting it right isn't always straightforward, though. Selecting the right width can have a huge impact. Channel width plays a big role in Wi-Fi performance.
