In an example, a first mobile device and at least a second mobile device of a plurality of mobile devices along a sequence of positions in an indoor route may be localized. Based on one or more sequencing criteria, the at least a second mobile device may be selected for an enhanced channel transmission associated with a received wireless signal. Further, from the at least a second mobile device, corresponding localization data based on the enhanced channel transmission may be received.
