1. A method of operation of a portable device, comprising:
- transmitting, by a processor, a radio frequency signal;
detecting, by the processor, a plurality of radio frequency identification tags based on a plurality of signals received in response to the radio frequency signal;
receiving, by the processor, from the plurality of radio frequency identification tags, first location information of a first radio frequency identification tag and second location information of a second radio frequency identification tag; and
determining, by the processor, a route from a location of the portable device to a location of the second radio frequency identification tag based on the second location information and the first location information, wherein the second location information further comprises map information showing a route between a location of the first radio frequency identification tag and the location of the second radio frequency identification tag.

Abstract
A method and system for location determination and guidance using radio frequency identification (RFID) are disclosed. A location of a mobile RFID reader can be determined by detecting stationary RFID tags located at fixed locations. Each RFID tag stores location information associated with its position as well as location information of at least one other RFID tag. The location information stored by each RFID tag can be used to direct a user from one RFID tag to another. Thus, RFID technology is also used to guide mobile RFID reader between the fixed locations of the stationary RFID tags.
