Then, the paper identi? es the important thing networking systems used for in-vehicle and inter-vehicle applications, contrasting their homes and indicating future challenges in the area of wireless automotive communications, with a focus on realtime elements. inter-vehicle sales and marketing communications are provided and in contrast, pointing out real-time related aspects, in Section 3. Finally, the daily news is summarised in Section 4. two Telematics Automobile telematics permits the application of a volume of new companies and applications integrating wi-fi communication technology into a automobile.

As a result, your vehicle acquires new capabilities while offering more solutions to people.

Examples of telematics services and applications are: ¢ Course-plotting and traf? c information systems ” A vehicle built with a telematics unit may direct a driver into a desired site, while rendering real-time traf? c data for a given route. ¢ Voice recognition and wireless Internet connection Drivers and the passengers can receive and send voiceactivated e-mails while on the road. ¢ Safety devices ” Accident avoidance systems, unsafe generating pro? ling, intelligent airbag deployment devices.

Communications between your vehicle as well as surroundings, elizabeth. g., various other vehicles and roadside things. Automatic airbag deployment noti? cation. Crash and side of the road assistance. An illustration is given by the General Motor Advanced Automated Crash Noti? cation (AACN) system available on many GMC OnStar TM -equipped vehicles. ¢ Burglar alarms ” Automobile antitheft and stolen vehicle tracking providers. Tracking and remote door unlocking can be provided by OnStar TM -equipped vehicles. ¢ Diagnostics and maintenance companies ” Remote control diagnostics and/or maintenance systems, vehicle and driver monitoring. 1 Advantages

Nowadays both areas which might be getting the majority of attention in automotive marketing communications are protocols and technology supporting x-by-wire applications, at the. g., Flexray [3], and protocols and systems for telematics and cellular applications. Automobile telematics refers to any kind of motor vehicle information or communication assistance that uses wireless interaction link. There are lots of applications pressing for the adoption of wireless sales and marketing communications in auto systems, both equally within the vehicle (in-vehicle communications) and between the vehicle and its surroundings (inter-vehicle communications).

Taking a look at in-vehicle communications, more and more lightweight devices, e. g., cellphones, portable GSM devices and laptop computers can exploit the possibility of interconnection with the vehicle. Also, several new applications will certainly exploit the possibility of inter-vehicle marketing communications, e. g., vehicle-to-vehicle [2] and vehicle-toroadside communications. This paper reveals the most common wireless protocols utilized for in-vehicle and inter-vehicle marketing and sales communications in the automotive aftermarket, and the ones that might be used in the near future.

Originally created for BAKING PAN deployment intended for low-cost, low-power, short-range wifi ad hoc interconnection, Bluetooth technology has quickly become extremely appealing as well for the automotive environment, as a potential automotive wireless networking technology. In response to interest by the automotive industry, in December 99 the Bluetooth Special Interest Group (SIG) formed the automobile Working Group. The Hands-Free pro? votre was the? rst of a lot of application level speci? cations from the Car Working Group. Using the new Hands-Free pro? le, products that implement the Wireless bluetooth speci? rules can facilitate automatic business of a interconnection between the car’s hands-free program (typically component to its audio tracks system) and a cellular phone. Bluetooth cellular products incorporating these new enhancements allow a smooth, virtually computerized interface involving the car and wireless products. Today, Wireless bluetooth allows hands-free use of a mobile phone through the car’s audio system or wireless headphones, resulting in better sound and control, and a secure solution to legal guidelines banning cellular phone use although driving. The Bluetooth SEJ, in November 2004, organized a threeyear roadmap to get future improvements to Wireless.

Prioritised goals include Service quality (QoS), reliability, power consumption, multicast capabilities, privacy improvements. Long-range overall performance improvements are expected to increase kids of really low power Bluetoothenabled sensors to approximately 100 meters. systems raised signi? cant interoperability problems which in turn ZigBee technology solves, offering a standardized foundation set of solutions for sensor and control systems.
