1. A femtocell mapping device, comprising:

  • a memory device storing a set of processor-executable instructions;

    interface hardware configured to communicate with one or more other devices, the one or more other devices including at least one of;

    a user device,a plurality of femtocells, ora femtocell gateway that is communicatively coupled to the plurality of femtocells; and

    a processor configured to execute the processor-executable instructions, wherein executing the processor-executable instructions causes the femtocell mapping device to;

    receive an indication, from the user device, the plurality of femtocells, or the femtocell gateway, via the interface hardware, the indication including information indicating that the user device has concurrently detected a presence of a first femtocell and a second femtocell, of the plurality of femtocells;

    receive, within a predetermined window of time;

    height information regarding the user device, the height information indicating at least one of;

    an altitude of the user device, ora floor of a building on which the user device is located,first signal strength information regarding a first signal strength between the user device and the first femtocell, that was obtained by the user device while the user device was concurrently in the presence of the first and second femtocells, andsecond signal strength information regarding a second signal strength between the user device and the second femtocell, that was obtained by the user device while the user device was concurrently in the presence of the first and second femtocells;

    determine a difference between the first signal strength and the second signal strength that were received during the predetermined window of time;

    determine a spatial relationship between the first and second femtocells based on the difference between the first and second signal strengths, that were obtained by the user device while the user device was concurrently in the presence of the first and second femtocells;

    approximate a first distance between the user device and the first femtocell based on the first signal strength;

    approximate a second distance between the user device and the second femtocell based on the second signal strength;

    determine a height of the first femtocell, based on;

    the approximated first distance between the user device and the first femtocell, andthe height information regarding the user device; and

    determine a height of the second femtocell, based on;

    the approximated second distance between the user device and the second femtocell, andthe height information regarding the user device.
