CheckFox Introduction


The CheckFox is a universal device for measuring Sigfox coverage. Most often, it's used by Sigfox Operators to determine signal strength when improving coverage and also integrators who need need to know if a location where they need Sigfox devices working is well covered.

The CheckFox comes in RC1, RC2, RC3 and RC4.

When you purchase the hardware, you also get access to the CheckFox Dashboard - the management platform where you can see all the data from your device. The platform needs to be connected to the Sigfox backend via API and callbacks and the device also needs to have a working SIM card inside.
