Track your everyday walking distance and exercise more to burn fat and boost body energy. 400 groups of RSSI data are taken at intervals of permanent distance; in Figure 8, the blue line is the real measurement value of RSSI in different distance; it can be seen that, with the increasing distance, different distance of RSSI overall has shown the trend of exponential attenuation, but there is a certain fluctuation which is influenced. The key variable that we need to estimate here is the path loss exponent (n). It is a measure of the power level that a RF device, such as WiFi or 3G client, is receiving from the radio infrastructure at a given location and time. I think a cesium clock would be sufficiently precise (it would vibrate almost 9 times in the time required for a radio wave to travel 1 foot in a vacuum, if I'm calculating it right), but the sync would be the problem, and the phone end of things as you say. The distance estimation model proposed by Texas Instruments for the Chipcon CC2420 radio is given as: RSSI = −(10 × n)log 10 (d) − A where A is the RSSI value measured when the separation distance between the receiver and the transmitter is one meter.
