ABSTRACT The disclosed method for wireless real-time human collision avoidance using link energy power factor to determine a distance of a wearer to an obstacle includes the steps of wearing, on a person, a wireless pendant. The wireless pendant (130) sends and monitors mesh-type network packet data to and from complementary wireless component tags (110A-C) attached to obstacles. The collected wireless component tag RF packet power factor is signal averaged and temporally smoothed using dynamically sized moving average convolution filters and storing the results at the wireless pendant. Using the signal averaging and temporally smoothing results, a Link Energy LE(x,y,z,t) result is created. The wireless pendant correlates the Link Energy LE(x,y,z,t) results with a near-field or far-field RF energy-to-range/distance profile table to derive various coefficients and calculates the current distance for the wireless pendant to the wireless component tags. A wireless pendant data collector server (120) can be provided.
