Within the designated Wi-Fi bands, such as the 2.4Ghz band, there are specific channels Wi-Fi access points may use. Although there are 14 available channels in the 2.4GHz band, each individual channel has a spread of approximately 22Mhz, which significantly overlaps surrounding channels. As such, multiple devices set to adjacent channels in a small physical space (such as an apartment block) will interfere with each other. For example, if you are having problems with Wi-Fi connectivity and sustained data transmission through your Wi-Fi router, it is recommended to check the operating channels of all detectable Wi-Fi access points to ensure your Wi-Fi access point isn’t operating on the same or adjacent channel as nearby access points.
