Purpose -The purpose of this paper is to describe a general purpose localization system, GRAIL. GRAIL provides real-time, adaptable, indoor localization for wireless devices. Design/methodology/approach -In order to localize as diverse a set of devices as possible, GRAIL utilizes a centralized, anchor-based approach. GRAIL defines an abstract data model for various system components to support different physical modalities. The scalable architecture of GRAIL provides maximum flexibility to

Findings -The authors show through real deployments that GRAIL functions over a variety of physical modalities, networks, and algorithms. Further, the authors found that a centralized solution has critical advantages over distributed implementations for handling privacy concerns. Originality/value -A key contribution of this system is its universal approach: it can integrate different hardware and software capabilities within a single localization framework. The deployment of such a system in academic and research environments allows researchers to explore issues beyond algorithms and investigate effects in real deployments.
