Determining the location of people and objects in indoor environments with a high degree of accuracy is a main technical obstacle to overcome in context-aware applications, a pillar of pervasive computing. This article focuses on the design and deployment of indoor positioning systems. We concentrate on the problems that our research team faced during the development and deployment of indoor positioning systems at a number of different locations. Our study demonstrates, via an extensive collection of case studies involving trial and error, that it is almost impossible to anticipate the development of situations that can make the installation process practically unfeasible. The deployment of our prototype system helped several research groups to identify applications for location technologies. The installation process became a priceless tool in evaluating how to deploy ubiquitous indoor technologies. Our main contribution to this field of research is a collection of advice regarding both technological and practical factors to consider when designing and deploying an indoor positioning system.
