1. A method of evaluating near range communications quality in an environment, the method comprising:
- obtaining 3D data describing an environment from a first data source;
processing the 3D data describing the environment to generate a ground-plane data set describing a ground-plane of the environment, and a 3D object data set describing 3D objects in the environment, wherein processing the 3D data comprises selecting 3D data to extract from the first data source to generate the ground-plane data set and the 3D object data set;
obtaining 2D data describing the environment from a second data source, and selecting 2D data from the second data source to combine with the ground-plane data set and/or the 3D object data set to improve the ground-plane data set and/or 3D object data set;
using the ground-plane data set and the 3D object data set to compute a propagation path between a first location and a second location in the environment, andcomputing a near range communications quality characteristic of the propagation path.

Abstract
A method and system configured to evaluate near range communications quality in an environment. Data describing an environment is obtained from at least one data source (202). The data describing the environment is processed (204) to generate a ground-plane data set (206) describing a ground-plane of the environment, and a 3D object data set (206) describing 3D objects in the environment. These data are used to compute (208) a propagation path between a first location and a second location in the environment, and a near range communications quality characteristic of the propagation path is computed (210).
