* The calibration value reflects the group delay of the radio front end and

* empirically by either conducted measurement in a known electrical length
* coaxial RF cable (where the design is connectorised) or by radiated
* measurement, at a known distance, where an antenna is present.

* accurately reflects the physical range, the calibration procedure therefore
* removes the average timing error from the time-of-flight measurement for a
* given design.

* design. Some typical values are provided in the next table.
