title: Challenges and issues of geolocation in clinical environment.
abstract: Reaching a good indoor geolocation without deploying extensive and expensive infrastructure is a challenge, because satellite positioning system is not available indoors. Geolocation could be of major use in healthcare facilities; to help care providers, visitors and patients to navigate, to improve movements and flows efficiency or to implement location-awareness systems. A system able to provide the location of a person in a hospital requires precision, multi-floors and obstacles management and should also perform in basements and outdoors. Such system needs also to be insensitive to environmental variations occurring in a hospital. These changes may be various kinds of obstacles. These can be the displacement of metallic objects, metallic machines, strong magnetic fields or simply human displacement. A system conforming to the above requirements can also answer various security questions, operational workflow management but also assist movement of people.
