A wireless sensor network consists of spatially distributed autonomous sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants or other such parameters.
These networks are deployed in many industrial and civilian application areas, including industrial process monitoring and control, machine health monitoring such as aeronautics, environment and habitat monitoring, healthcare applications, home automation, traffic control monitoring and so on.
Application markets for WSN are driven by a variety of factors but the primary one in almost all cases is an increase in efficiency of the place, process or application to which the WSN is applied, leading to cost savings and profit increases.
Issues to be resolved:
- lifetime cost of ownership because high power consumption requires regular battery changes
- poor performance because of the inability of narrowband radio schemes to communicate reliably in highly reflective RF environments such as manufacturing plants (multipath fading issue)
Solving these Issues:
DecaWave’s technology allows longer battery operation thanks to its dramatically reduced power consumption (compared to other technologies available on the market), it also resolves the multipath fading issue as a result of its use of IR-UWB, enabling higher degrees of flexibility in the deployment of wireless networks and sensor positioning, together with increased communication reliability.
