Abstract
Indoor locationing using radio frequency based tags includes distributing a plurality of radio frequency based tags at mapped locations within the indoor environment. The radio frequency based tags periodically transmit their identity information in a message. A mobile device in proximity to at least one of the radio frequency based tags receives the message. A location of the mobile device is associating to the mapped location of the radio frequency based tag identified in the received message.
