Abstract
Ultra Wideband (UWB) radar integrated Fine Timing Measurement (FTM) based indoor locationing may be provided. First, a computing device may detect that Non Line of Sight (NLOS) conditions exist based on a spatial layout derived using the UWB radar. Next, the computing device may determine a delay error, in response detecting that the NLOS conditions exist, based on the spatial layout. Then the computing device may adjust FTM times using the delay error.
Claims20
A method comprising:
- detecting, by a computing device, that Non Line of Sight (NLOS) conditions exist based on a spatial layout derived using Ultra Wideband (UWB) radar;
- determining a delay error, in response detecting that the NLOS conditions exist, based on the spatial layout;
- and
- adjusting Fine Timing Measurement (FTM) times using the delay error.
A system comprising:
- a memory storage;
- and
- a processing unit coupled to the memory storage, wherein the processing unit is operative to:
- detect that Non Line of Sight (NLOS) conditions exist based on a spatial layout derived using Ultra Wideband (UWB) radar;
- determine a delay error, in response detecting that the NLOS conditions exist, based on the spatial layout;
- and
- adjust Fine Timing Measurement (FTM) times using the delay error.
A non-transitory computer-readable medium that stores a set of instructions which when executed perform a method executed by the set of instructions comprising:
- detecting, by a computing device, that Non Line of Sight (NLOS) conditions exist based on a spatial layout derived using Ultra Wideband (UWB) radar;
- determining a delay error, in response detecting that the NLOS conditions exist, based on the spatial layout;
- and
- adjusting Fine Timing Measurement (FTM) times using the delay error.
