A proposal for hyperbolic location analysis based on the difference between pairs of received signal strength, called the stationary signal-strength difference (SSSD), has been made. Its location accuracy, in general, is limited because of two impairment factors: One factor is a high level of SSSD measurement error resulting from the shadowing,(More)
Applications for the user's geolocation of wireless services continues to grow. Developing an effective technique for finding geolocation in wireless cellular networks is imperative. This paper presents a hybrid positioning technique to the user's geolocation. The technique is based on combining the propagation delay with relative signal strength. In our(More)
