- W20325812 abstract "While the emergency call (eCall) system is becoming legislated in Europe by 2010, it may bring a potentially large market to some of its stakeholders. Both public and private sectors have some progress in eCall development, but while looking at the cost, it is still quite expensive and the vehicle owners are reluctant to pay for it. The cost of an eCall device is a very important factor. The report has conducted a pricing survey on different eCall implementations. By the pricing survey, all integrated eCall systems seem to cost at least €70. A low cost solution at €50 is possible, but it would have to go for a chipset solution in a standalone eCall system. Using software GPS can further reduce the cost as well as provide a better compatibility with new positioning technologies. While the specifications of eCall are still not finalized, there is a risk of using obsolete radio technologies, if developed now. Even though there are voices proponing different technologies to be adopted, GSM and GPS are still the most suitable ones. The A-GPS, EOTD and the Galileo positioning system are also very much needed to be taken into consideration. As an in-vehicle device, the eCall system is also required to provide up-to-date radio technologies for 15-20 years, which is the expected life time of a vehicle. A software-defined radio solution would provide the desired flexibility. However, because of the limitations of today’s configurable RF front ends, an alternative solution which is only reconfigurable in the digital architecture is proposed by this report. Moreover, the report found out that reconfigurability does not equal high cost. A solution using OMAP and FPGA can give decent reconfigurability while still keeping the cost at an acceptable level. The cost for such a solution, around €100, is the same as the cost of existing commercial eCall systems but it could provide much more capabilities." @default.
