—    authorized and authenticated access of users and services, including security;
—    payment;
—    preparation of indoor data which are necessary for indoor navigation;
—    low-level communication protocols required to transfer and share data from and to a roadside ITS station or a central ITS station;
—    other issues dependent on implementation of an instance of indoor navigation.
