ABSTRACT:: 
Location is one of the most important context information that an
ubiquitous-computing application may leverage.  Thus understanding the
location systems and how location-aware applications interact with
them is critical for design and deployment of both the location
systems and location-aware applications.  In this paper, we analyze a
set of traces collected from two small-scale one-building location
system and two large-scale campus-wide location systems.  Our goal is
to study characteristics of these location systems ant how these
factors should be taken into account by a potentially large number of
location-aware applications with different needs.  We make empirical
measurements of several important metrics and compare the results
across these location systems.  We discuss the implication of these
results on location-aware applications and their supporting software
infrastructure, and how location systems could be improved to better
serve applications' needs.  In places where possible, we use
location-aware applications discussed in existing literatures as
illustrating examples.
