Abstract
A wireless communication arrangement provides GPS coverage in areas where GPS satellites or macrocells are not directly detectable by a mobile station that is used for placing an emergency call. A detector detects a plurality of GPS satellites and provides a composite GPS signal that is re-radiated through a distributed antenna system to provide GPS signal coverage within a selected area such as inside of a building. The signal reach at each re-radiator assembly is individually controlled to keep the composite GPS signal coverage area within a selected limit. A mobile station used to place an emergency call reports the composite GPS signal information in a data call or SMS message that is associated with the emergency voice call. That information is then used for GEO-location to determine the location of the mobile station. A disclosed example includes a technique for addressing a scenario where a mobile station directly detects a satellite and detects the composite GPS signal.
