The core functionality of eCall / ERA Glonass requires an embedded computer that continuously monitors crash sensors and a GPS receiver in order to initiate an automated data and voice call via a dedicated GSM modem in case an emergency occurs. A key requirement for eCall is that both data and the voice call must utilise the same physical voice channel because SMS and GPRS do not provide the necessary service priority or availability.
"We have implemented a comprehensive in-band modem test case on the real trial-network in Russia," said Jeffery Song, technical support director at SIMCom. "The extremely positive results of the tests validated SIMCom's in-band modem capabilities and it fully meets the standards requirements, and it has convinced our customers that SIMCom is completely ready to help them win more business opportunities."
