A Review of Antennas for Indoor Positioning Systems
International Journal of Antennas and Propagation, 2012 This paper provides a review of antennas applied for indoor positioning or localization systems. The desired requirements of those antennas when integrated in anchor nodes (reference nodes) are discussed, according to different localization techniques and their performance. The described antennas will be subdivided into the following sections according

A Pervasive Indoor-Outdoor Positioning System
Journal of Networks, 2008 A new concept called Always Best Located (ABL) is introduced to achieve a pervasive indoor- outdoor positioning system. Designed as a combination of WLAN and GPS, this hybrid positioning system is shown to yield ubiquitous coverage and best-effort accuracy in any environment.
