NXP Semiconductor demos car communication
sys based on IEEE802.11P
NXP Semiconductors N.V. has presented a live demonstration
of car-to-x (C2X) communication on a public road in the
Netherlands. NXP has co-developed the C2X platform with
Australian-based Cohda Wireless.
C2X communication uses IEEE802.11p, a wireless standard
designed specifically for automotive applications. This
allows cars to communicate with each other (car-to-car)
as well as with intelligent traffic infrastructure (car-to-infrastructure)
around them. The newly developed C2X platform from NXP and
Cohda actually "sees" around corners in order
to recognize traffic blocks or risks before they are visible
to the human eye. Drivers therefore receive early warnings
of cars hidden from sight behind trucks or approaching from
around corners. Other use cases are warnings about emergency
vehicles and traffic jams, or traffic light signals allowing
drivers to adjust their speed and optimize driving.
The C2X platform is able to meet the requirements of the
automotive industry: reliable signal reception for fast-moving
objects even in difficult surroundings, cost-efficient design,
and flexible programming. It uses Cohda's Advanced IEEE
802.11p radio and is based on NXP's multi-standard radio
reception platform. NXP's expertise as global leader in
car entertainment semiconductors and Cohda's patented reception
algorithms are critical factors for successful development.
Kurt Sievers, senior vice president and general manager
of the Automotive business at NXP Semiconductors, explains:
"Connecting the car to the environment demands in-depth
expertise in secure connectivity, Software-Defined Radio
architectures, and telematics. These technologies are at
the very heart of NXP's automotive portfolio. NXP has therefore
set a high priority on gaining the pole position in connected
mobility. The SPITS project has been extremely valuable
for us as it brought experts and research partners from
all parts of the value chain together all working towards
the same goal: efficient and sustainable mobility solutions."
