Introduction

The offering of ASSP products for Location Aware Wireless Sensor Networks is mainly based on two technologies. First the LOST technology for the ranging and the tracking and second the Wavenis technology for the communications. Location is a key parameter in many business processes, not only in logistics and transportation but also in security, healthcare, asset management, and distributed sensing and control systems. Location tracking will lead to increases in productivity, reliability, and safety.

Traditionally GPS is being promoted as the answer to all major location tracking needs, but doesn’t work properly in an indoor environment. For indoor environments, Essensium has developed the LOST technology that combines sub-meter accuracy, offered by Ultra Wide Band techniques, with low power consumption and that can deal with the presence of many battery-powered wireless sensor nodes and many signal reflections. At the same time, coexistence with exisitng WLAN network environments is guaranteed. This technology also does not require tedious calibrations and will keep the same accuracy even in dynamic changing environments.

The use of the ultra-low-power Wavenis communication technology that also operates in the ISM band and that is based on proven communication protocols, will allow Essensium to deliver products that combine world best performance in both ranging accuracy and battery life-time extension for location aware Wireless Sensor Networks. This technology has already proven its performance in applications such as Automated Meter Reading in several millions of devices and will be futher integrated into the ASSP products of Essensium by the close cooperation of Essensium and Coronis.
