What is the definition of range?

Hi,

I was looking at a dataset and was wondering what the definition of range was. Is it the TOF or is it the distance calculated using TOF.

Thanks!

Your assumption is right. TOF stands for Time of Flight, which is a time unit. The speed is speed of light, and with a formular you get the distance between two uwb unit which is referred to as range. TWR is a common algo : Two Way Ranging for distance measurement between nodes.

Also have a look at APS013. This appnote expalins TWR and the different ways of doing TWR
