After calibration is applied. Approximately +/-15cm without calibration.
2 Ranging standard deviation is measured at -85 dBm power level.
3 Note: in a typical PDoA based system the computed angle of arrival (AoA) accuracy is better than the PDoA accuracy by
a factor of approximately two i.e. if PDoA accuracy is ±10° then AoA accuracy is ±5°.
4 For optimal PDoA performance a crystal offset of greater than |5| ppm is required between devices.
