Can the air-Q Be Used Without Wi-Fi?

The air-Q can also be used without Wi-Fi. After starting up, the device records all data on the included SD card. The data can then be viewed and retrieved from anywhere, without a router, via a direct Wi-Fi connection (smartphone --> air-Q). As soon as a Wi-Fi network comes within range again, the air-Q connects to it. Depending on the setting (cloud upload enabled), the data is then also uploaded to the cloud retroactively.

By the way, the air-Q can also store multiple Wi-Fi networks. It then connects to whichever known network has the strongest signal.
