Abstract: Principle of underground RFID-based LANDMARC location system was briefly introduced. For low location precision of LANDMARC location system caused by underground multi-path effect, improved schemes of the LANDMARC system were summarized form the view of accuracy of RSSI, selection of the nearest point and weight formula. Research directions of the underground RFID-based LANDMARC location system were put forward, which were system layout and central location algorithm.-
