AirO is intended for technical and not-too-technical owners of Wi-Fi capable iOS devices. It displays the health of the Wi-Fi (“Local Area”) connection, and measures the characteristics of a “Wide Area” connection to a server deeper in the network. It can be used to answer questions like: • What’s wrong with my Wi-Fi today? • How strong is my Wi-Fi signal? • Is there evidence of wireless interference? • Is the problem in the Wi-Fi connection, or out on the Internet (or corporate network)? • Is the overall connection to the data center good enough to run my corporate apps?
