Wireless Communications for Intelligent Transportation Systems: Technologies and Markets
PracTel Inc., Dec 2008
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.
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.
