Testing a Commercial Sensor Platform for Wideband Applications based on the 802.15.4 standard

Wireless Sensor Networks are increasing their capacity to handle larger amounts of data. These networks, which were born with the purpose of collecting environmental information, could be also used for wideband applications, e.g. transmitting audio and / or video data streams. The European project EAR-IT [1] uses acoustic detection to make smarter cities. The idea is to make large-scale deployments and use sounds to create innovative applications. Current technology can be a limitation in terms of performance. This document shows what parameters are relevant to be measured in a 802.15.4 Wireless Sensor Network to determine its suitability to wideband transmission of multimedia streams. TST-Sistemas is the commercial sensor platform chosen for the evaluation and qualification.
