A Active Noise
Cancellation
Cabin ANC systems provide a
significantly quieter and more
enjoyable driving experience by
capturing and actively canceling
noise in the vehicle cabin. In
addition, ANC systems can
enable increased fuel economy by
reducing the weight of the existing
metal, glass and other materials
needed to reduce cabin noise.

D Emergency Call
Emergency call systems are
designed to save lives by enabling
fast response to automobile
accidents. In the event of an
accident, the system initiates
a call to emergency services,
immediately shares GPS details
of vehicle location, and establishes
a voice connection between the
occupants and emergency
service personnel.

C Ethernet AVB
Accurate voice recognition enhances
vehicle safety and convenience. It
enables drivers to remain focused
on the road ahead while making
adjustments to in-vehicle systems
while providing high-fidelity hands
free communication via mobile
phone. Next generation systems
require higher sample rates to
provide optimized handset
compatibility and communication
with cloud-based services.
Ethernet AVB enables timesynchronized, low-latency network
communication of audio and video
data in automobiles.
