Handicapping the field of possible MIPS suitors

Whether it is Continental Tyre’s AutoLinQ in-vehicle infotainment and connectivity solution, BMW’s Connected Drive online route guide, or Cisco’s mobile demonstration and networking technologies’ showcase vehicle, Network on Wheels, an increasing number of manufacturers, suppliers and technologists are working intensively on researching Machine-to-Machine (M2M) communications solutions for vehicles.

Secure, fast mobile communications in emergencies Many cars already feature Internet connectivity, enabling drivers to retrieve e-mails, conduct a Google search, request remote diagnosis from a shop following a breakdown, or display empty parking places. But there are many manufacturers taking an additional step to develop vehicles that not only receive data, but can also actively send messages.

One such example is the European Commission’s emergency eCall system, which is on target for installation in every new car by 2015.  The aim of the program is to reduce the number of road casualties, and the eCall system does this by supplementing the vehicle's on-board electronics with a permanently-installed SIM card and GPS module. These additional connectivity features link emergency calls to the airbag sensors, so that if an accident occurs, information about the vehicle’s location, time of the accident and identification number can be sent to rescue services, along with the driving directions, severity of the accident and even the number of fastened seatbelts within the vehicle. Consequently, rescue services can send help to the accident site immediately or establish a voice connection with the vehicle. This technology is a testament to the European Commission’s claim that its eCall international emergency system could save around 2,500 lives a year and estimates that it will also result in a 15% drop in the number of casualties involving seriously injured persons.

In-car M2M solutions have also been developed to make life easier for drivers, such as Daimler’s car2go project in Austin, Texas (screen shot of the project site pictured nearby ). Members have a card that they can use to reserve a vehicle ahead of time or as transport is required. They do this by simply holding their card up to a specially-installed reader on the windshield of car2go’s branded blue and w

Vehicle-to-vehicle communications Another example of innovative, secure communication in traffic is the development of secure Vehicle-to-X communications. One example is Deutsche Bahn’s solution for networking car-sharing, electro-mobility and fleet management. Following the successful secure transfer of data to and from Deutsche Bahn’s car-sharing vehicles in a pilot project in Friedrichshafen, the company is providing additional telematics services through mobile M2M communications technology. These include finding, booking and opening vehicles using a cell phone. The added telematics systems also integrate the vehicles to three networks, demonstrating how cars, trains and energy systems can be effectively linked to each other. Cars can be rented spontaneously using a special mobile app, which also transfers data such as the range and power levels within the car to the user’s smartphone via M2M communication technology so they know when to charge and for how long.

The aim of Vehicle-to-Vehicle communications and Internet connectivity within vehicles is to detect traffic jams promptly and prevent them from getting any worse. Reducing driving time and stress leve

By contrast, RF solutions have no line-of-sight requirement, and in the relatively small confines of a vehicle, a single transmitter can reach all headphone locations.

Multiple audio channels Generally, IR offers a single broadcast channel. Multiple transmitters attempting to transmit different content interfere with each other. Analog versions therefore can only handle a single audio stream which is fairly limiting in a modern vehicle with multiple displays and other audio content sources. Some IR solutions improve on this by time division multiplexing several audio channels onto a single digital IR link. The drawback of this approach is that all of the audio content must be brought to one location to be multiplexed before IR transmission.

RF solutions have the ability to allocate separate radio channels to different audio streams. Radio sources can be distributed throughout the vehicle (see figure below) to be as close as possible to the audio source and headphones can select the desired audio content by tuning I”’ to the desired radio channel.

Broadcast While headphones allow an individual to enjoy the audio content of his or her choice, it is also desirable for several passengers to be able to share content, for example when all are watching the same display.

Infra-red technology is essentially a broadcast medium and therefore all headphones that have a line-of-sight path to the transmitter can share the same audio stream.
