Connected car technology: Cellular V2X outperforms DSRC/ITS-G5 in comprehensive tests as mobility industry moves towards 5G (part 1) |
|
Munich, 9 November, 2018 (APA/OTS) - As regulators worldwide are looking into future rules for connected cars technologies, the 5G Automotive Association has conducted tests to compare the performance of 802.11p/DSRC (known in Europe as ITS-G5) and Cellular V2X PC5 radio technologies in delivering V2V (Vehicle-To-Vehicle) safety messages. |
The test results show that Cellular V2X (Vehicle-to-everything)
direct communications technology, consistently - and in many cases
overwhelmingly - outperforms 802.11p/DSRC. With a natural evolution
path towards the low latency and high bandwidth benefits of 5G NR,
C-V2X also demonstrated superior performance in several dimensions,
including the following:
- Enhanced reliability over extended communications range;
- Better non-line-of-sight performance; and
- Greater resiliency to interference (e.g. arising from other
devices)
These performance advantages are particularly important in the most
difficult environments such as non-line-of-sight scenarios (e.g.,
around a corner, highway queue forming etc.), where resident
on-board sensors and radars have certain limitations.
Reliable and timely radio performance is a crucial requirement that
all those with a stake in transport safety depend on to deliver
critical safety applications. Such test procedures are a
prerequisite to comparing the available radio technologies, and the
results are very clear: C-V2X direct communications (PC5) performs
better. C-V2X is commercially available and reuses the decades long
investment into protocols and upper layer applications to improve
safety, deliver traffic efficiency, and support automated driving.
The design and execution of each experiment was set up to ensure
that environmental conditions, radio frequency parameters, system
integration details, and physical structures were consistent when
comparing 802.11p/DSRC and C-V2X direct communications.
As yet another strong signal about the global momentum behind
C-V2X, 5GAA today counts 102 members (40% from Europe, 35%
Asia-Pacific and 25% Americas), an increase of 60% since January
2018, quite a movement for a 2-year-old organization.
5GAA brings together the automotive and ICT industry leaders from
all world regions among which carmakers, Tier-1 suppliers, mobile
network operators, chipset manufacturers, test equipment vendors,
telecom suppliers and traffic signal suppliers in order to continue
C-V2X field tests and to accelerate in-vehicle and infrastructure
commercial deployments, foreseen beginning in 2019 globally.
Maxime Flament, CTO of the 5G Automotive Association (5GAA) said
"these test results demonstrate that C-V2X direct communications, is
today's most cutting-edge technology for connected and automated
driving, and the best to finally deliver upon safety and traffic
efficiency. Hence why C-V2X ecosystem is growing so rapidly - the 5G
Automotive Association has now more than 100 members who all believe
in C-V2X as the future of mobility."

Notes to Editors:
The V2V radio performance tests were conducted by 5GAA members over
a period spanning six months from March through September 2018.
Vehicle-to-Everything (V2X) communication is an essential enabler
of cooperative, connected and automated mobility that can be
supported today by two concurrent technologies: 802.11p (Wi-Fi
based) and Cellular V2X (C-V2X).
C-V2X is the family of cellular technologies designed for
automotive applications, standardized by 3GPP, the global
telecommunications standard development organization. C-V2X combines on a single technology platform a direct short-range
mode operating over ITS spectrum (not requiring any network coverage
or subscription) and a long-range mode using traditional cellular
networks operating over mobile network operator licensed spectrum. The above-mentioned tests were conducted using only the C-V2X
direct short-range communication mode without any network
involvement.
C-V2X current realization is based on LTE-V2X (3GPP Release 14,
completed in March 2017), and will evolve into 5G-V2X (also called
5G New Radio or "5G NR") to deliver additional capabilities and
support new services (as Release 16, to be completed by 3GPP by end
2019).
About 5GAA The 5G Automotive Association (5GAA) is a global cross-industry
organization of companies from the automotive, technology and
telecommunications industries (ICT), working together to develop
end-to-end solutions for future mobility and transportation
services. Created in 2016, the Association is comprised of over 100
members whose mission is to develop, test and promote communications
solutions, initiate their standardization and accelerate their
commercial availability and global market penetration, to address
society's connected mobility and road safety needs with applications
such as automated driving, ubiquitous access to services and
integration into smart city and intelligent transportation. For more
