1. A method for generating mapping information, comprising:
detecting one or more barriers based on measurement information associated with a plurality of radio frequency signals exchanged with one or more wireless nodes, wherein the measurement information include round trip time measurements and received signal strength measurements;
determining a location and a material composition for each of the one or more barriers based at least in part on the round trip time measurements and the received signal strength measurements; and
generating mapping information based on the location and the material composition of each of the one or more barriers.
