System and method of calibration for establishing real-time location

A system for determining location information pertaining to a location of a portable device relative to an object, said system comprising:

• an object device disposed in a fixed position relative to the object, said object device having an antenna configured to communicate wirelessly with the portable device via a communication link;
• a controller configured to determine location information about the portable device relative to the object;
• said controller including an adapter locator configured to store a device-type parameter associated with a signal characteristic of communications between the portable device and said antenna, wherein said device-type parameter corresponds to a device-type of the portable device;
• said controller including a reference locator coupled to said adapter locator, said reference locator configured to obtain from memory one or more reference parameters operable to facilitate determining location information based on a signal characteristic of communications wirelessly transmitted between a reference device and said object device, wherein said adapter locator is configured to affect an output of the reference locator based on the device-type parameter;
• and
• wherein said controller is configured to obtain said device-type parameter corresponding to the device-type of the portable device, said controller configured to determine location information with respect to the portable device relative to the object based on output from said adapter locator and said signal characteristic of communications wirelessly transmitted between the portable device and said object device.
