Method and System for Calculating Directional Information Including Estimated Distance to Recently Moved or Newly Tagged Objects to a Moving, Wireless Enabled Device |
摘要 |
A method is disclosed for calculating a distance to objects or a nearest object to a wireless enabled device. The method includes the steps of broadcasting a signal by the wireless enabled device to data tags, receiving by the data tags the signal by the wireless enabled device, and obtaining by each of the data tags a signal strength indicator of the wireless enabled device based on the signal from the wireless enabled device. Each of the data tags in a range transmits a signal to the wireless enabled device including the signal strength indicator of the wireless enabled device. Each signal strength indicator of the wireless enabled device is communicated to a positioning and communication system. |
