Abstract: Methods and apparatuses of providing assistance data of a venue to a mobile device are disclosed. According to aspects of the present disclosure, one approach is to compute a visibility area that may satisfy positioning criteria for a venue, for example a mobile device may observe sufficient signals for positioning in the visibility area. Then, positioning assistance data may be generated that includes the information of signal characteristics in this visibility area. With this approach, the size of the positioning assistance data can be reduced and can be used more efficiently for positioning applications without losing useful information.
