Based on received radio channel information from a positioning server (112, 212, 408, 508), positioning nodes (104a-d, 204, 206, 410, 412, 510) identify (S-430, S-538, 704) a radio signal from said communication device, measure (S-432, S-433, S-540, 706) the strength of said received signal and sends (S-434, S-435, S-542, 708) signal strength information and position information of the positioning nodes to said positioning server. The positioning server then determines (S-436, S-544, 610) 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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and arrangements for high accuracy positioning","description":"This disclosure relates to methods and arrangements for positioning of a communication device (102, 202, 208, 402, 502) in a communication system.
