Evaluating severe noise interference in IEEE 802.15.4 based location systems

This paper studies the impact of severe ISM noise interference in IEEE 802.15.4 based location systems, in particular the LOPES project. The architecture and operation of the location system are presented as well as the underneath physical mechanisms supporting the IEEE 802.15.4 noise immunity. A test-bed is proposed and the assessment scenario is described by focusing on the trial parameters. Results show that this technology is able to operate in extreme harsh environments. However, this has a significant impact in the location systempsilas performance.
