摘要：
The location of a mobile terminal may be determined in response to signals received from a plurality of RFIDs. Information from a plurality of RFIDs for determining a location of a mobile terminal is received by the mobile terminal. The mobile terminal may maintain an in-range list that comprises all the RFIDs in which the mobile terminal is currently within their coverage range. The location of the mobile terminal is calculated in response to the received information for determining a location by calculating the common coverage area of the RFIDs in the in-range list.
