  • Patent number: 10327145
    Abstract: An approach is provided that receives, from a radio frequency identification (RFID) tag included with a device, at least three different charge times. Each of the charge times corresponds to a different RFID reader that separately charges the RFID tag with each of the RFID readers being at a different geographic location. A distance between each of the RFID readers and the RFID tag is approximated based on the respective charge times and these approximate distances are used to identify a geographic position of the RFID tag using trilateration. The geographic position of the RFID tag is then used to determine whether to allow the device wireless access to a computer network.

  • Patent number: 10250343
    Abstract: A technique for measuring Reference Signal Received Power (RSRP) is provided. The RSRP is measured based on Cell-specific Reference Signals (CRSs) provided by cells (102, 104) of a mobile telecommunications network (100). The CRSs of at least two of the cells overlap in time and frequency. As to a method aspect of the technique, a time offset for sub-frames received from the at least two cells is determined. The overlapping CRSs are received for a group of sub-carriers. A coarse channel state is estimated for each of the at least two cells by multiplying the received overlapping CRSs with a function of phase-shifted CRSs. The phase-shifted CRSs of different sub-carriers in the group include a phase-shift that corresponds to the determined time offset. The RSRP is measured for each of the at least two cells based on the estimated coarse channel state.
