Abstract: The location of a wireless mobile device may be estimated using, at least in part, one or more pre-existing Network Measurement Reports (“NMRs”) which include calibration data for a number of locations within a geographic region. The calibration data for these locations is gathered and analyzed so that particular grid points within the geographic region can be determined and associated with a particular set or sets of calibration data from, for example, one or more NMRs. Regions may be defined as a function of any number of parameters and respective predetermined ranges thereof in the NMRs. An intersection of these defined regions may be determined and the location of a mobile device may be estimated as a function of the intersection.

Abstract: A system and method for estimating a location of a wireless device in a wireless communication system having a plurality of nodes and a plurality of location measurement units (“LMUs”). A set of signal samples from a first wireless device and a second wireless device may be collected by one or more LMUs in a search window. A first time of arrival (“TOA”) is determined, and a second search window is estimated as a function of the first TOA. A second TOA may be determined within the second search window at a second node or one of the LMUs from the set of signal samples. A range estimate of the wireless device may then be determined, and an estimated location of the wireless device may be determined as a function of the first uplink TOA, the second uplink TOA, or the range estimate and second TOA.

Abstract: A method for detecting an IS-95 signal without knowledge of a spreading code for the IS-95 signal is provided. A received baseband signal is rotated through a plurality of phase-shifts. For each phase-shifted baseband signal, an in-phase component or a quadrature component of the phase-shifted baseband signal is realigned. The in-phase and quadrature components are multiplied by a PN short code to partially despread the components. The partially despread in-phase and quadrature components are multiplied and integrated. The integrated despread in-phase and quadrature components are compared to a threshold value. In response to exceeding the threshold value, the received baseband signal is identified as an IS-95 signal. The method may be implemented on a repeater for repeating signals between multiple sources.

Abstract: An apparatus for detecting a spread spectrum signal in a wireless signal environment includes at least one antenna for receiving spread spectrum signals, such as UMTS signals, from a signal source in the wireless signal environment. In one embodiment, a detection circuit is configured for correlating a code in signal received by the apparatus with a set of possible codes for spread spectrum signals in order to detect the existence of a spread spectrum signal. In another embodiment, a detection circuit is configured for obtaining at least one reference frame of data from a received signal. The detection circuit is further operable for correlating a segment of the reference frame with a repeated segment of at least one subsequent frame of data in order to detect the existence of a spread spectrum signal. A repeater might incorporate such an apparatus wherein the variable gain of the repeater is adjusted based upon the correlation and the detection of a spread spectrum signal.

Abstract: A method of modifying calibration data used to geo-locate a mobile station located in an indoor environment is disclosed. When a mobile station is located indoors, the signal strength of signals received and/or transmitted by the mobile station have the tendency to be lower than the strength of the signals received by a mobile station located outdoors. As a result of these lower signal strengths, geo-location efforts which rely on signal strengths may result in unsatisfactory location accuracy. Modifying pre-existing calibration data obtained outdoors may provide a way to simulate indoor calibration data characteristics.

Abstract translation: 公开了一种修改用于对位于室内环境中的移动台进行地理定位的校准数据的方法。 当移动台位于室内时，由移动台接收和/或发送的信号的信号强度倾向于低于由位于室外的移动台接收到的信号的强度。 由于这些较低的信号强度，依靠信号强度的地理定位工作可能导致不能令人满意的定位精度。 修改户外获得的现有校准数据可以提供一种模拟室内校准数据特性的方法。

Abstract: A system for treating a surface to prevent or limit offensive odors and/or microbiological activity and improve indoor air quality includes electrostatically charged particles of anatase titanium dioxide and a substrate or surface on which these particles are received. The electrostatic charging of the particles, in conjunction with the substrate being oppositely charged, provides a self-leveling effect to the particles. The particles may be incorporated into an HVAC system defined by ductwork in which untreated air including organic matter flows, is treated, and is ejected as clean air. Methods of treating surfaces or fluids containing organic matter include providing electrostatically charged particles of anatase titanium dioxide and contacting the organic matter therewith to initiate photocatalytic oxidation processes in which the organic matter is broken down into less offensive constituents such as carbon dioxide and water.

Abstract: A system and method modifies calibration data used to geo-locate a mobile station. Calibration data measured via a calibration data collection device may contain errors due to the physical limitations of the collection device and/or the collection process. Any data collection device may produce some degree of signal degradation or drop-out. Dead reckoning provides a remedy for signal drop-out, however, it often produces data results that may be unsatisfactory to perform an accurate location estimate. To ensure the integrity of the collected calibration data, a data modification and/or data replacement algorithm may be implemented to enhance the accuracy of the collected data. In addition, current collection procedures used to generate a calibration database may be laborious, time-consuming and expensive. Simplifying the test and measurement equipment needed, and the procedures for obtaining calibration data may save time and expenses.

Abstract: A system and method of determining calibration data at non-calibrated location points is disclosed. A mobile station may be geo-located at most locations, if not all locations, within communication range of one or more serving and/or neighboring base stations of a mobile network. Calibration data may be collected and stored in memory via a data collection procedure. Known calibration data for locations proximate to the mobile station may be necessary when attempting to geo-locate the mobile station. A geographical region may be calibrated via a standard calibration data collection procedure, however, various obstacles, such as, buildings, mountains, ponds etc. may inevitably create deficiencies in the calibration data for one or more areas of the region. Certain techniques may be applied to estimate the calibration data of areas that have not been properly calibrated.
