With the use of 4G and 5G mobile networks and the announced abandonment of 2G and 3G technology by telecommunications operators, the next generation eCall is coming. An important step towards its validation represents a successful 3 weeks long international testing event organized under the frameworks of EU co-funded project sAFE and NG eCall Plugtests Event 2020, steered by ETSI. The testing infrastructure was provided by Slovenian partners in sAFE project, namely interoperability test lab Sintesio as a host and Iskratel as a technical partner.
