1. A method comprising, at a processor-based device:
- receiving at a mobile wireless device at least one wireless message including antenna information for one or more wireless access points, wherein the at least one wireless message transmitted from at least one of the one or more wireless access points, and wherein the antenna information comprises antenna gain pattern information for the one or more wireless access points; and
generating, at the mobile wireless device, based, at least in part, on the antenna information for the one or more wireless access points included in the at least one wireless message transmitted from the at least one of the one or more wireless access points, a heatmap representative of values measurable, by the mobile wireless device, at a plurality of locations from signals transmitted by the one or more wireless access points, wherein generating the heatmap comprises;
measuring at multiple locations signal characteristic values for the signals transmitted by the one or more access points; and
determining, based on the antenna gain pattern information for the one or more wireless access points received in the at least one wireless message from the at least one of the one or more wireless access point, and based on the signal characteristic values measured at the multiple locations from the signals transmitted by the one or more wireless access points, interpolated signal characteristic values at locations different from the multiple locations at which the signal characteristics values for the signals transmitted by the one or more wireless access points were measured.
