DISTANCE DETERMINATION OF A MOBILE DEVICE |
| 摘要 |
A first energy of a signal received from a mobile device is computed at a device based on information available at a physical (PHY) layer of the mobile device. A second energy of the received signal is computed. A path-loss exponent of the received signal is computed based on a line-of-sight (LoS) factor (lfactor) of the signal. A distance of the mobile device to the device is computed based on the first energy, the second energy, and the path-loss exponent of the received signal. |

1. A device comprising a signal processing unit to:
compute a first energy of a signal received from a mobile device based on information available at a physical (PHY) layer of the mobile device; compute a second energy of the received signal; compute a path-loss exponent of the received signal based on a line-of-sight (LoS) factor (lfactor) of the signal; and compute a distance of the mobile device to the device based on the first energy, the second energy, and the path-loss exponent of the received signal. |
