First Claim
1. A positioning system for positioning at least one mobile device (100) by utilizing radio frequency technology on a positioning area of said system, wherein the system comprises at least one stationary base station (106), i.e. a transceiver, which comprises at least one antenna (102, 104) for transmitting signals comprising at least position information to at least one mobile device (100), which position information of the signals comprises information on an effect area of the antenna (102, 104) by using certain transmit power, which effect area of the antenna is dividable on two or more sections based on power measurement, calculation and/or judging, and said mobile device (100) comprises at least one antenna (108) for receiving said signals, and which system comprises as said mobile device (100) an electronics unit for measuring at least intensities of received signals and for processing and storing received signals, which comprises position information, and for transmitting signals, which comprise at least position information, through its antenna (108) automatically and/or upon request to said at least one stationary base station 106.
