Keysight, from eCall signal generation to call quality analysis all in one
Published2018.03.20 12:34Expected to use domestic 5G network, but government-led initiative needed
Keysight showcased eCall (emergency disaster network communication) testing equipment solutions, which are mandatory for vehicles exported to Europe and Russia, at the Automotive Testing Expo 2018 held from March 13 for 15 days.
Currently, Russia has been applying ERA-GLONASS since 2017, and Europe will mandatorily implement the eCall system controlled through 2G and 3G voice networks starting from April this year. eCall is a call processing system that transmits basic data called the minimum set—vehicle information, vehicle location, number of occupants, etc.—to the emergency disaster network when an accident occurs.
Keysight showcased equipment at this Automotive Testing Expo to test the overall quality of such call processing.
To emulate 2G and 3G call processing, they equipped the UXM E7515A acting as a base station, MSG equipment that generates GPS and GNSS data allowing vehicle location identification during accidents, and audio quality analysis equipment that checks call quality when modules transmit data and connect to the emergency disaster network during calls.

Kim Hyun-sung, manager in charge of Keysight's eCall solution section at the Automotive Testing Expo, responded to questions about domestic eCall construction by stating, 'Currently, domestic telecommunications companies are in the stage of commercializing 5G communication, and the eCall section is also mentioning 5G in current forums.' However, he added, 'In Korea's case, a government-led eCall system is expected to enable faster implementation.'
Additionally, Keysight showcased a radar target simulator testing equipment, which is one of the basic test equipment for autonomous vehicle safety functions at the Automotive Testing Expo.
It is automotive radar target simulation in the 76 to 77GHz range with a minimum physical distance of 1m between simulator and DUT, thus saving installation space. Furthermore, it can be expanded and configured to the full range of 10 to 450m or two fixed ranges, and provides either a single horn with embedded transceiver or dual horns in transmit and receive configuration.
Visitors to Keysight's booth on that day noted that Keysight's radar testing equipment, eCall equipment, and Ethernet testing equipment appeared to be the most practical equipment that could be used immediately.
