Claim One:
1. A method of characterizing a waveform path, by an electronic device, the method comprising: accessing training data in a training database assembled from waveforms transmitted between at least one pair of training wireless devices, the training database including line-of-sight and non-line-of-sight labels and feature vectors representing aspects of the waveforms transmitted between the training wireless devices; learning a function using the training data, the function being nonparametric with respect to features representing aspects of a waveform transmitted via the waveform path between a first wireless device and a second wireless device; by the electronic device, characterizing the waveform path by evaluating the function learned with a feature vector extracted from the waveform received at the first wireless device from the second wireless device to make a decision regarding a presence of an obstruction between the first and second wireless devices or to determine a likelihood of an obstruction between the first and second wireless devices; and reporting the determined decision or likelihood of an obstruction between the first and second wireless devices to a device accessible to a user, another wireless device, or a different physical or logical layer in a wireless network including multiple wireless devices.
