Abstract
Systems, methods, and devices are described for determining a physical location of a wireless device. A receiver may be configured to receive associations between anchor locations and sensor nodes, wherein each sensor node uses near field communications to identify an anchor location. The receiver may also receive signal strength measurements from the wireless device measuring the signal strength of wireless sensor nodes. Arrangements may also be configured to determine physical locations of the sensor nodes based on physical locations of anchor locations and utilize received signal strength measurements with the determined physical locations of the sensor nodes to determine the physical location of the wireless device.
