    摘要: A Wide Area Sensor Network (WASN) is disclosed that utilizes wideband software defined radios (SDRs) to monitor RF energy over a wide frequency range, detect when critical frequencies are being jammed or otherwise interfered with, and locate the source of the interference so that the interference can be eliminated. The WASN may use one or more geolocation techniques In addition, the WASN may detect and locate unauthorized transmitters as well as estimate the transmitted power of authorized transmitters to assure they are not transmitting more power than authorized.

    摘要: A Network Autonomous Wireless Location System (NAWLS) is designed to allow for precise location of a mobile device (e.g., a cell phone) without interconnection to, and with minimal disruption of, the local wireless communications network. Using distributed radio network monitors (RNM) and a managed network emulator (NE); mobile devices are sampled, acquired or captured. Once triggered by the RNM or NE, an untethered wireless location system (U-WLS) is used to calculate a precise location. The U-WLS; comprising mobile receiver sites, each capable of self location, exchanging information with other components of the NAWLS, and receiving or exchanging signals from the mobile device; utilizes various network-based and handset-based wireless location techniques dependent on the deployed options. In addition, the NAWLS includes data links interconnecting the U-WLS, NE and RNM.

    摘要: A method for use in controlling a mobile device's access to one or more wireless communications networks (WCNs) with an overlaid wireless location system (WLS) includes monitoring a set of one or more predefined signaling links of at least one WCN, and detecting an event associated with the mobile device. Next, using a low-accuracy location function of the WLS, the system determines that the mobile device is within a defined area of interest and is potentially within a defined quiet zone. Next, using a high-accuracy location function of the WLS, the system determines a precise geographic location of the mobile device and based thereon confirms that the mobile device is within the quiet zone or at least within an area of ambiguity around the quiet zone. Finally, the mobile device's access to the wireless communications network is limited, e.g., according to a pre-defined rule established by the carrier. This approach allows finer definition of the fenced area while also minimizing the load on the high-accuracy location function. The proximity threshold is preferably based on the accuracy of the underlying location technology.
