System and method of determining real-time location

A secondary portable device for communicating with a primary portable device and an object, said secondary portable device comprising:

• an antenna system configured to communicate wirelessly with the primary portable device and the object, wherein the primary portable device and the object are configurable to communicate wirelessly via a primary communication link;
• a controller operably coupled to the antenna system, the controller configured to receive one or more connection parameters from the primary portable device, wherein the one or more connection parameters enable the secondary portable device to communicate wirelessly via a secondary communication link different from the primary communication link;
• and
• the controller configured to communicate wirelessly, via the secondary communication link, with the object based on the one or more connection parameters received from the primary portable device, wherein at least one of presence and location of the secondary portable device is determined based on wireless communications transmitted via the secondary communication link, wherein a confidence metric is associated with a location determined with respect to the primary portable device and the object, and wherein the confidence metric is adjusted based on the at least one of presence and location of the secondary portable device determined based on wireless communications transmitted via the secondary communication link.
