Is bluetooth broadcasting practical and useful?

Bluetooth (BT) has become a standard for personal area networks connecting mobile devices including mobile phones, PDAs, laptop computers, headsets, keyboards and other devices. The most usual usage of BT networks is to connect one device to another device. However, the BT technology can also be used in other ways. This paper describes experiences from developing and exploring a BT broadcasting system with the focus on investigating the usefulness and practical issues related to BT broadcasting. In particular, the paper looks at what kind of application areas BT broadcasting can be used for and how privacy can be established in such environments. We also consider some collaborative services that can be provided through BT broadcasting.
