Intelligent Transportation Systems in 4G Era
PracTel Inc, Jan 2011, Pages: 205
This report is written for a wide audience of technical and managerial staff involved in wireless ICT-related Intelligent Transportation Systems (ITS) projects. The report aim is to present for such specialists major directions and trends in wireless ICT that can lead ITS into the 4G era. The report continues the Practel’s project that addresses advanced communications developments in support of ITS.
In particular, this report:
1. Analyzes the global ITS developments and related markets.
2. Updates the analysis of technologies and markets for 5.9 GHz Dedicated Short Reach Communications (DSRC). 5.9 GHz DSRC was originally developed for the U.S. market; and currently it is at the beginning of commercialization. The report addresses this technology specifics and benefits; recently, the EU also approved 5.9 GHz band for its DSRC systems. Currently, the major application of DSRC is electronic tolling; it is expected that the range of applications will grow significantly with maturing of the technology.
3. Analyzes CALM (Communication Access for Land Mobile), which represents an ambitious attempt to provide a platform for a wide range of present and future communications requirements for ITS. As such, it cuts across several ongoing standards-making efforts, including those of the ITU (such as NGN).
CALM supports continuous communications between a vehicle and the roadside using a variety of communication media, including cellular, 5 GHz, 63 GHz and infrared radios. CALM can support a range of applications, including vehicle safety and information, as well as entertainment for driver and passengers.
The scope of CALM is to provide a standardized set of air interface protocols and parameters for medium and long range, high speed ITS communication using one or more of several media, with multipoint and networking protocols within each media, and upper layer protocols to enable transfer between media.
4. Updates the analysis of Long Term Evolution (LTE) technologies and market; the technology is being standardized and appreciated as the 4G era wireless technology. It opens a wide range of applications for ITS; currently, auto industry R&D and communications equipment manufacturers are working together on the concept of the LTE - equipped car. The technology allows creating of ITS infrastructural networking with a high bit rate, QoS and other important features. Major service providers are offering LTE-based services already in 2010.
5. Analyzes specifics of Wireless Sensors Networks (WSNs), their development and markets. It is expected that in the near future smart sensors will create a basis for an intelligent source of information for processing in the ITS control centers. The industry, initially, was military-oriented; but the progress in IC miniaturization, developing such wireless technologies as ZigBee, UWB and other (that are cost-efficient and utilize low-consumption radios) opened a stable market for commercial applications, and particular for the ITS. The report provides details of WSN features, markets and benefits.
Altogether, the report addresses latest trends in the wireless ICT developments for ITS that reflect the 4G wireless communications evolution. This analysis shows a complex picture of multiple efforts from the industry and standardization organizations to utilize advanced communications to support efficient Intelligent Transportation Systems.
Target Audience:
This report is important to a wide population of researches, technical and sales staff involved in the developing of ITS-specific wireless communications 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 wireless communications to support ITS 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.
