In-vehicle systems (IVS) are designed to connect to a public safety answering point when an automobile is an accident. They transmit a minimum set of data to emergency personnel that includes the vehicle’s GPS coordinates. Rohde & Schwarz recently developed a setup for manufacturers of these automatic in-vehicle systems (IVS) for reliability testing.
The setup is comprised of the R&S CMW500 wideband radio communication tester and the R&S SMBV100A vector signal generator with integrated global navigation satellite system (GNSS) simulator. The system verifies if the IVS modem can in fact initiate the emergency call, transmit the data – most importantly, the GPS coordinates, and establish a voice connection with emergency services. A specific type of eCall application software (R&S CMW-KA094) has been developed for this very application.
In essence, the setup offers a standard-compliant test solution for the wireless and GNSS-capable components of eCall in-vehicle systems and contributes to reduced response times to automobile accident sites.
