| Summary: | 碩士 === 國立交通大學 === 資訊科學系 === 90 === Location-based services have been a hot topic for several years. Lots of technologies are addressed in recent years. There are three kinds of solutions for positioning: handset-based, network-based, and software-based solutions. We choose software-based solution to determine user’s location because it is low-cost and simple for network operators or users. In the thesis, we proposed a method to evaluate the accuracy for software-based positioning by calculating the area of segment. Furthermore, we could adjust the power range of base stations in order to improve the accuracy in positioning.
