nanoLOC TRX Transceiver - Ranging
High Performance RF Transceiver with Location Awareness and Robust Wireless Communication
Ranging
nanoLOC Ranging uses a methodology called Symmetrical Double-Sided Two-Way Ranging (SDS-TWR) developed by Nanotron Technologies and is part of the nanoLOC nTRX Driver.
Three different ranging modes are available:
- SDS-TWR 3W_A provides measurement results to Peer station A (the local station that requested the ranging)
- SDS-TWR 3W_B provides measurement results to Peer station B (the remote station with which the location station is performing ranging)
- SDS-TWR 2W_PP operates identical to 3W_A except it uses time data from the previous ranging request to reduce energy consumption and quicker generation of ranging results
The SDS-TWR ranging methodology is:
- Symmetrical as the first ranging measurement from Peer A to Peer B is mirrored by a second ranging measurement from Peer B to Peer A
- Double-Sided as the ranging measurement is performed between two peer nanoLOC - enabled devices
- Two-Way as a Data packet and an automatic hardware acknowledgement provide the time values used for determining the ranging measurement
