Abstract
This disclosure relates to methods and arrangements for positioning of a communication device () in a communication system. Based on received radio channel information from a positioning server (), positioning nodes (-) identify (S-, S-) a radio signal from said communication device, measure (S-, S-, S-) the strength of said received signal and sends (S-, S-, S-) signal strength information and position information of the positioning nodes to said positioning server. The positioning server then determines (S-, S-) the position of the communication devices based on the received signal strength measurements and the position information of the positioning nodes. High accuracy in-door positioning of communication devices is achieved.
