Volvo Cars EMC testingfrom faraday to awitar
Björn Bergqvist Volvo Car Corporation
IEEE / SNRV meeting2018-12-05
• Faraday was opened in 1991
• Agreement for cooperation
• Volvo Car Corporation 17 weeks/year
• Two shifts
• Models: 345 (-91), 440 (-96), 460 (-96), 480 (-95), 240 (-93), 740 (-92), 940 (-98), 850 (-96)

Today, field trails.
Tomorrow, testing of wireless performance in AWITAR.
Advantages with AWITAR:- The environment can be controlled.- The tests are repeatable.- The tests can be performed,
~1 year earlier than today.
