LizardSystems Wi-Fi Scanner is a free app that locates visible wireless networks along with all corresponding information, including the network name (SSID), signal strength (RSSI) and quality, MAC address (BSSID), channel, maximum and achievable data rate, security, and much more.

It is useful for normal access point users who need to find the signal strength distribution for their wireless network at home or choose a position for their access point for optimal signal quality.

Using Wi-Fi Scanner, you can evaluate wireless networks' allocation by channel and select the least congested bandwidth for their access point, allowing them to increase their connection speed significantly.

Besides, LizardSystems Wi-Fi Scanner is an indispensable tool for corporate network administrators in performing tasks such as configuration, planning, and monitoring security parameters on business wireless networks.

Set up is easy, and you do get 10 days to test it on the unregistered version, but they do require you to complete a simple registration to continue to use it for free (non-commercial).
