An indoor location positioning system comprises at least one processor, Wi-Fi scanners, and a RSSI fingerprint database. The Wi-Fi scanners and the RSSI fingerprint database works with the processor. The Wi-Fi scanners are positioned at locations within an environment that is partitioned into interconnected zones. The Wi-Fi scanners receive anonymous probe messages from Wi-Fi devices that are present in the environment during a calibration phase of the indoor location positioning system. The RSSI values are collated to create RSSI fingerprints corresponding to the different locations respectively. One or more of the Wi-Fi scanners are used as anchor scanners to counter the difference in transmit power levels of different Wi-Fi devices that result in different RSSI fingerprints for the different types of Wi-Fi devices, wherein the RSSI value at each anchor scanner is subtracted from the RSSI values at rest of the Wi-Fi scanners to generate the RSSI fingerprint.

User dynamics through Wi-Fi device localization in an indoor environment

The present invention provides a method and a system for scheduling and mitigating cross-cell interference. The system comprises a plurality of N network nodes, each having a baseband processor and a transmit antenna N, capable of handling multiple input multiple output (MIMO) channels, communicatively coupled with a plurality of K co-residents user equipment (UEs); a central scheduler configured to control scheduling of said plurality of network nodes; wherein each network node is configured to select a plurality of UEs and provide the shortlisted UEs to the central scheduler; the central scheduler in turn identifies a target set of UEs and the co-residents for each network node; and the network node is configured to pre-select signal-to-noise power to the target UEs without impacting transmission of co-residents UEs.
