Claim 15

The method of claim 12, wherein step (c) comprises measuring based on ray tracing between said each candidate and the set of transmit locations.

Claim 16

The method of claim 13, wherein the step of providing the known environment comprises accessing a memory including data about each of plural reflective surfaces and each of plural diffractive surfaces of the known environment, and the step of ray tracing comprises: (i) determining a first image tree for a first transmit location within the known environment, having a predetermined scope, by: (A) determining first order images of the first image tree by determining, for each of the plural reflective surfaces and each of the plural diffractive surfaces, respectively, within the predetermined scope, a first order image and a scope; (B) determining second and higher order images of the image tree by repeating step (b)(i), for a predetermined number of reflections and diffractions, such that for each of the plural reflective surfaces and plural diffractive surfaces, respectively, a next order image and a scope of the next order image is determined; (ii) selecting a first candidate antenna location and back-tracing from the first candidate antenna location using the first image tree to determine each one of plural propagation paths from the first candidate antenna location to the first transmitter source location; (iii) determining a signal quality change for said each one of plural propagation paths based on predetermined signal characteristics; (iv) determining a first receive signal quality measure at the first candidate antenna location based on the signal quality change for said each one of plural propagation paths; and (v) repeating steps (i) through (iv) for each further transmit location of the set of transmit locations to determine further receive signal quality measures, the first and further receive signal quality measures forming a first set of receive signal quality measures for the first candidate antenna location; (vi) repeating steps (i) through (v) for each remaining candidate of the candidate antenna locations.
