Why Do I Need to Use a Wireless Channel Scanner?
We’ve come to depend on WiFi networks. It’s no longer just our personal electronic devices that connect to the Internet. Now, common household appliances and even our cars require an Internet connection to download updates from remote servers, upload diagnostic information, and make available all the features they come with.
As more people than ever connect to the Internet wirelessly, the density of WiFi networks increases and it becomes difficult to achieve decent download and upload speeds
. This happens because the WiFi frequency range is inherently limited. The 2.4 GHz frequency range, which most routers operate on, is divided into several channels. Each of these channels has a WiFi channel width of just 20 MHz, but the individual channels are spaced only 5 MHz apart. Consequently, adjacent channels overlap and interfere with each other. To avoid this interference, it’s recommended to leave three or four channels clear between used channels.
Most WiFi users are not aware of this recommendation, and even those who are sometimes don't adhere to it because they don’t have a reliable WiFi channel scanner
Windows app that would allow them to see which WiFi channels are the busiest and which are used the least.
