How Precise Should Localization Be? A Quantitative Analysis of the Impact of Delay and Mobility on Reliability of Location Information

Location information has become an important enabler for services that interacts with the physical environment. Focus has therefore been on providing accurate information on the user´s position, but less on the reliability of the information. This paper gives a methodology to evaluate numerically the reliability of estimated positioning of mobile devices, and shows how the methodology can be applied to decide upon the trade-off between reliability and accuracy of location systems.
