Connected Car Technology: Cellular V2X Outperforms DSRC/ITS-G5 in Comprehensive Tests as Mobility Industry Moves Towards 5G

PR76224

MUNICH, Nov. 10, 2018 /PRNewswire=KYODO JBN/--

    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 information, visit 5GAA's
