<p>An infield radio communication device (100) operates in a communication system (200, 300) to dynamically identify and/or share location information to form and update a geo-fence or border. A single infield radio device (100) can be used to provide electronic location markers which can be updated in real time to create a geographical fence or border as the device (100) changes location. Additional infield radio device(s) (100) can also be used to share location markers for the creation of the geographical fence or border.</p> |
