  • ENHANCED POSITIONING METHOD SUITABLE FOR LOW FREQUENCIES
    Publication number: 20190310361
    Abstract: A method, node, and device for determining a traveling distance for sub-GHz radio signals wherein the range and accuracy are significantly improved in relation to prior art systems. The solution relates to receiving at least one data packet, bias at least part of the data packet radio signal, and using the biased section to perform a distance calculation. The distance calculation can for example be used in a positioning system.
