Testing range of our NOVA 436Q installation

I was wondering if there’s an easier way (than driving around with an indoor modem), to test the range of our connection.

When I run the tests with the indoor modem in my car and I get out of range, I have to double back to retrieve the connection; which makes it hard to tell how far we are actually reaching.

Just seeing there’s any equipment, software, or applications out there that would make it easier to discover how far we are reaching to create a connectivity map for our network.

Fingers crossed I am not alone on this.
