To solve issues with signal interference, you need to somehow make wireless network activity visible, and that’s where WiFi analyzers come in. In densely populated areas, the demand for WiFi connectivity is so large that it’s causing major issues with signal interference, which can lead to slowdowns and connection drops. If you could see wireless network activity with your eyes, you would most likely be surprised by how many wireless signals are in range.
