Abstract
The invention relates to a wireless system and methods for obtaining a range or location estimate of a target mobile device (10) within a wireless network, wherein the apparatus is adapted to: request a ranging or positioning service from a positioning constellation (60) formed by one or more ranging capable anchor devices (14) and or access devices (20) of the wireless network; receive one or more response groupcast/broadcast message; perform a range or location estimate or a ranging measurement based on the information in at least one response broadcast message.
Claims25
