Abstract:
1. A method comprising: receiving, at a server, beacon data indicative of a location of an asset tag device, the beacon data determined based on beacon signals received at the asset tag device from multiple transmitters that are each associated with a respective one of group values identifying a corresponding one of a plurality of assigned transmitter groups comprising the respective each of the multiple transmitters, each of the assigned transmitter groups associated with a group of proximately deployed transmitters; identifying, from the group values, a minority group value associated with a fewest number of transmitters from which the beacon signals were received at the asset tag device; excluding a portion of the beacon data associated with the identified minority group value to generate non-excluded beacon data associated with non-excluded group values; and determining, at the server, the location of the asset tag device based on the non-excluded beacon data and based on the non-excluded group values respectively associated with non-excluded transmitters from the multiple transmitters from which the beacon signals received at the asset tag device were transmitted, wherein the non-excluded group values associated with the non-excluded transmitters and the non-excluded beacon data do not include the minority group value.
