CEWITT · Low Cost and low Energy GNSS-based WIreless Tag for asset Tracking and monitoring

Nowadays, all long range asset tracking applications make use of the GSM/GPRS network to transfer the position of the items being monitored at regular intervals to treatment servers and end-users. These communication channels call for expensive subscriptions with telecom operators which limit their use to those applications which are worth the investment either from an economic or safety standpoints. Yet, many additional ‘tracking’ applications could be envisaged provided that long range communication costs could be decreased.The SigFox Wireless company has developed the TransFox Ultra Narrow Band technology which brings drastic enhancements in terms of range, capacity, autonomy, power consumption and total system cost, compared to competing technologies. Targeted to be deployed as a wide area wireless communication system, the technology allows offers higher coverage than GSM/GPRS with the same output power as WiFi or Bluetooth.The STERELA company benefits from a strong market positioning for traffic counting and road data collection equipment. Based on its market knowledge, STERELA is convinced of the opportunity to combine such new radio-communication systems with their own leading edge expertise in low consumption electronics to open new GNSS applications in the road area.In this overall context, the CEWITT project aims at developing an innovative wireless tag and the associated SIGFOX wireless communication and GNSS geo-positioning capabilities with the objective to ensure the integrity and cost effectiveness of Pay per Use parking & Identification of free parking slots applications in Urban Areas.The optimisation of EGNOS / GPS capabilities, map matching techniques, correlation with SIGFOX signals and the development of specific algorithms working on EGNOS corrected pseudo-ranges and pseudo range differences will allow maximising the level of accuracy and integrity needed in the applications.
