Abstract
A positioning system has a central unit receiving identity and timing information; and based thereon determines a respective position in an area of each of a set of entities. Each entity carries a mobile unit repeatedly transmitting a radio message including the identity information. The positioning system also contains at least three base stations, each receiving the radio messages from the mobile units; and based thereon, forwards the identity and timing information to the central unit. During a measurement period, the central unit registers positions of the entities as a trace for each mobile unit. The central unit checks whether, during the measurement period a first predefined number of traces are interrupted during a first threshold interval, and the predefined number of traces are interrupted in a first zone, which exceeds a first threshold size. If so, a capacity alarm with respect to the first zone is generated.
