Abstract: A facility is equipped with floor tiles. Each tile is equipped with transmitters that transmit on specific frequencies. A particular set of frequencies identifies a particular floor tile and a particular segment on the floor tile. A user electromagnetically couples to one or more antennas of the tile, acting as a signal path for the signals on the particular set of frequencies. A receiver detects these signals, and the information about the frequencies detected and relative signal strength may be used to determine a location of the user within the facility. Receivers in the floor tiles allow a first tile to transmit its set of frequencies and a second tile to receive the set of frequencies and determine where the user has stepped from. By concatenating these steps a path of the user may be determined. Receivers in shelves facilitate disambiguation of one user from another when interacting with items.

Abstract: A gain control circuit in a wireless distribution system (WDS) is provided. The gain control circuit generates a combined digital communications signal based on a number of received radio frequency (RF) communications signals. The combined digital communications signal has a digital amplitude(s) representing a summed analog power level(s) of the RF communications signals in a predefined number of binary bits. When the summed analog power level(s) exceeds a maximum analog power level represented by the digital amplitude(s) in the predefined number of binary bits, the gain control circuit determines a selected RF communications signal(s) causing the summed analog power level to exceed the maximum analog power level and attenuates the selected RF communications signal(s) to reduce the summed analog power level to below the maximum analog power level. As such, it is possible to achieve a calculated balance between performance, complexity, and cost in the gain control circuit.
