1. A device, comprising:
a processing system including a processor; and
a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:
determining a location for each of a plurality of anchors having distributed positions in a demarcated area;
determining anchor pairs from the plurality of anchors according to the location of each of the plurality of anchors, wherein each anchor pair of the anchor pairs has an overlapping coverage area, resulting in overlapping coverage areas, and wherein the determining the anchor pairs enables a determination of a mobile device location for a mobile device relative to the anchor pairs within the demarcated area; and
identifying, based on the overlapping coverage areas of the anchor pairs, a transmission schedule for the anchor pairs to transmit respective wireless signals for the determination of the mobile device location, wherein certain wireless signals of the respective wireless signals each provides a respective identification of a measurement technique that the mobile device is to employ for that wireless signal for determining the mobile device location, wherein the measurement technique comprises a time difference of arrival measurement technique when an anchor corresponding to the respective identification is located in a first type of area within the demarcated area and a time of arrival measurement technique when an anchor corresponding to the respective identification is located in a different type of area within the demarcated area, and wherein the transmission schedule includes overlapping scheduling for two or more anchor pairs of the anchor pairs.
