Abstract
This report addresses marketing and technological issues of the new DSRC
technology, licensed in the U.S. in the 5.9 GHz band. This technology, as it
seen today, may eventually replace existing systems: the 915 MHz DSRC in the
U.S. and the 5.8 GHz DSRC in Europe.
The development of this new technology is a response on the users and
government organizations demand to establish the industry standard, system
compatibility and improve road safety.
Vehicular communications are becoming a reality, driven by navigation safety
requirements and by the investments of car manufacturers and Public Transport
Authorities. Safe navigation support through wireless car- to- car and car-
to- curb communications has become an important priority for car manufacturers
as well as Municipal Transportation Authorities and communications standards
organizations.
Standardization plays a very important role in the success of any potential
large-scale deployment of a DSRC technology. A national deployment requires
interoperability of equipment and systems coming from many different
manufacturers, hardware / software certifications, compliance testing and
security. A complete suite of standards is currently under development within
IEEE and other standard organizations and these are expected to eventually
migrate into ISO on a global scale. IEEE 802.11p addresses the physical layer
and medium access control layer (MAC) called 802.11p module. The upper layers
(network and others) of the communication stack are being developed within
IEEE 1609 (Wave Management, Channel Management, & Resource Manager) and IEEE
1556 (DSRC Security) through the normal IEEE committee process. The vehicle
aspects are being developed and evaluated through VSCC / CAMP (represents
seven major automotive manufacturers) and SAE is developing the message set,
data dictionary and application framework standards.
5.9 GHz DSRC is the emerging communication technology that offers standardized
ITS products and benefits in national large-scale deployments. U.S. DOT and
the automotive OEMs will be the strategic players making deployment decisions
in the year 2008 timeframe (when the IEEE 802.11p is planned for ratification).
5.9 GHz DSRC systems provide a significant enhancement in communication
capabilities over all previous ITS systems. DSRC will support multiple uses in
vehicle / public safety and commercial applications that cannot be achieved
today. DSRC is a cost-effective communications service, especially when
compared with current cellular and satellite systems.
The technology can be leveraged for Open Road ETC (electronic Toll Collection)
and mobile 802.11 Wi-Fi deployments, creating nationally interoperable systems
and networks. DSRC is the technology for the 2010 decade and beyond.
Key Findings:
- At the present time, DSRC systems are not compatible with each other
- In the U.S., the prevailing technology is 915 MHz DSRC
- In Europe, the prevailing technology is 5.8 GHz DSRC
- 5.9 GHz DSRC has many advantages, and it is under development by various
research and standards organizations
- This technology is envisioned as a replacement of all existing DSRC. This
replacement will be gradual, and for several years new and old systems will
co-exist. It is not expected that the new systems will create any noticeable
interference into the old systems
- The commercial introduction of 5.9 GHz systems is expected in 2008 when
IEEE ratifies the 802.11p standard
- At the present time, the 5.9 GHz systems market is mostly limited to
research and testing
- The 5.9 GHz technology maturing is expected in the 2012-2014 time frame.
Research Methodology
Considerable research was done using the Internet. Information from various
Web sites was studied and analyzed. Evaluation of publicly available marketing
and technical publications was conducted. Telephone conversations and
interviews were held with industry analysts, technical experts and executives.
In addition to these interviews and primary research, secondary sources were
used to develop a more complete mosaic of the market landscape, including
industry and trade publications, conferences and seminars.
The overriding objective throughout the work has been to provide valid and
relevant information. This has led to a continual review and update of the
information content.
Target Audience
This report is important to a wide population of researches, technical and
sales staff involved in the developing of high-speed wireless services and
products for transportation. It is recommended for both service providers and
vendors that are working with related technologies. The report also helps to
understand issues associated with relationship between ITS wireless
communications and other technologies.
