The road transport system is experiencing an increasing demand regarding connectivity. There is an increasing wide range of technologies available supporting different application need and purposes. Examples of such technologies are CEN-DSRC (road tolls); Bluetooth, Cellular: 3G, LTE, LTE-A; WLAN 802.11a, b, g, n; Global Navigation Satellite Systems (GNSS, including GPS, GLONASS, and Galileo); SDARS and ITS-G5 and WAVE communication using 802.11p.
All systems require a reliable connection combining high performance in the antenna system with efficient PHY and MAC layers. In the most demanding case of high frequencies such as 802.11p and CEN-DSRC, the electrically large vehicles make it difficult to achieve the 2D isotropic antenna diagram that is often desired by the application. Antenna installations will very likely require multiple positions not only to achieve low antenna correlation, but also to cover different directions. The overall coverage depending on the design will most likely be both a competitive edge between OEMs as well as an enabler for some demanding applications and services. Therefore it is very important for Volvo Cars and their subcontractors to have knowledge and good methods and processes for designing and specifying those wireless communication systems to achieve high quality products and to be able to offer good and competitive services.
The aim of the project is to increase the understanding of how antenna systems, including the possible use of MIMO (Multiple Input Multiple Output)-techniques, should be designed and implemented in demanding vehicle/machine environments. The focus is to improve reliability in communication for safety-critical applications and to cater for other demanding services.
An important part is to create knowledge of what antenna designs should be used, where they should be positioned, and how the antenna signals should be processed. Even if the project aims at optimizing performance, special requirements for vehicles must be taken into account. These include component and installation costs, design considerations, environmental robustness, and manufacturing demands.
This is a Chase project.
