Abstract
Vehicular communications are becoming a reality, driven by navigation safety
requirements and by the investments of car manufacturers and Public Transport
Authorities all around the world. 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 wireless structures for ITS.
This report addresses marketing and technological issues of wireless
technologies for ITS.
Particular, the following technologies were considered:
- 1. 5.9 GHz DSRC- This technology, as it is becoming more and more
obvious today, may eventually replace the 915 MHz DSRC in the U.S. and the 5.8
GHz DSRC in Europe. 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 2009-2010 time frame. 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 communication service, especially when compared with current
cellular and satellite systems.
- 2. CALM (Continuous Air-interface, Long and Medium Range)
represents an ambitious attempt to provide a platform for a wide range of
future communications requirements for ITS. As such, it cuts across several
ongoing standards-making efforts, including those of the ITU (like NGN). The
aim of CALM is to provide wide area communications to support ITS applications
that work equally well on a variety of different network platforms, including
2G (GSM/GPRS), 3G (IMT-2000), 4G (IMT Advanced); as well as satellite,
microwave, mm-wave, infrared, WiMax and short - range technologies like WiFi.
- 3. The report also concentrates on the analysis of multiple ITS
networking projects that are conducting in various parts of the world. These
projects, which are organized by the industry with participation of standard
organizations (such as ETSI, CEN and other), are testing various technologies
to find and define optimal ways to enhance ITS with reliable means of
communications. It seems that 5.9 GHz DSRC is in the wining position-it was
recently approved for use in Europe (though Japan and some other countries
utilize different technologies). CALM is coming into the play as an
“universal platform” allowing utilization of a set of wireless
protocols.
The report also provides marketing statistics for some of the discussed
technologies.
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.
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.
