However, from a troubleshooting perspective, active scanning has a few disadvantages.

Existing libraries allow applications to easily perform active scans without worrying about low-level implementation details, such as hopping between channels, sending probes and processing the responses from the access points. Active scanning is supported by basically all the Wi-Fi drivers, so your computer, smartphone, etc., and pretty much every Wi-Fi scanner program use this method. The method, and the probe request and response frames involved in this process, were designed specifically to carry out the scan as fast as possible. By default, beacons are transmitted at a rate of approximately 10 per second.ДЄn active scan is the recommended mechanism to efficiently find nearby wireless networks. A client device must listen on a channel long enough to catch a beacon from a nearby access point. On the other hand, during a passive scan, the client device listens for beacons, which are specific frames transmitted by the access points to announce their presence and, similarly to a probe response, also include the configuration and capabilities of the wireless networks they service. These responses describe the configuration and capabilities of each of the wireless networks managed by the access point. During an active scan, the client device searches for wireless networks by transmitting probes and listening for responses from the access points in range. There are two methods to perform Wi-Fi scanning: active and passive.

Just be aware that the technical details described here are specific to WiFi Explorer Pro and the macOS frameworks and libraries that it uses, so please do not assume the behavior and limitations of Wi-Fi scanning are the same for all platforms. I believe it is important to understand the differences between each scan mode so that you know what to expect in terms of scan precision and performance. In this blog post, I will briefly talk about how Wi-Fi scanning works, and then I will focus on how this process is accomplished in WiFi Explorer Pro, including the pros and cons of each scan mode. Meanwhile, applications such as WiFi Explorer Pro can use it to aid in the monitoring and troubleshooting of the wireless infrastructure.

Client devices use this information to determine which networks they can join or roam to. As part of this process, a scanning device or application gathers information about the signal strength, channel, security configuration and capabilities of nearby networks. computer) or an application discovers the wireless networks that are in range of the Wi-Fi adapter. It is the mechanism by which a client device (e.g. Wi-Fi scanning is one of the basic functions in a wireless network.
