Since NetSpot is a software scanner, we’ll be using the term WiFi scanner to describe software scanners.Īs will become obvious later in this article, many leading WiFi scanners are so intuitive that even people with no previous experience with them and little to no technical knowledge can use them to discover causes of WiFi issues, such as co-channel interference and poor signal coverage. In terms of features, however, software scanners typically exceed hardware scanners, and the same can be said about their ease of use. Because different laptops and mobile devices have different WiFi modules, the same software scanner may provide vastly different results when used on two different devices. Software scanners On the other hand, software scanners depend on a laptop or mobile device and its WiFi module.Hardware scanners are most commonly used by technicians in the field because they free them from having to carry a heavy laptop with limited battery life. Hardware scanners: As the name implies, hardware WiFi scanners are physical devices, typically of the handheld variety.WiFi scanners can be divided into two categories: The collected information includes everything from network names and their security settings to signal strength, noise level, interference, and more.
The purpose of a WiFi scanner is to discover all nearby WiFi networks and collect as much information about them as possible.
