The big trend on everyoneís agenda at the moment is big data, but in the world of machine-to-machine communications (M2M) itís the small data that matters. M2M communications is helping automotive Original Equipment Manufacturers (OEMs) better understand their vehiclesí performance and driving behavior. This enables OEMs to develop and evolve relationships by having informed conversations with their customers (dealers, suppliers and consumers) and deliver new, innovative value added services.
By using an embedded SIM card that transmits data wirelessly via a secure mobile network, M2M can collect important granular pieces of information from a vehicle which be put to a wide variety of useful purposes. David Levine, Global Head of Automotive Business Development, Vodafone explains the potential applications for M2M and the opportunities its adoption presents to automotive software and hardware engineers.
The industry drivers
In terms of the machine-to-machine industry as a whole, the automotive sector is by far the biggest, eclipsing its use in utilities, consumer goods and manufacturing. Some analysts predict that the sector will generate up to $199 billion in revenue in 2020. Adoption is being driven largely by EU regulations supporting the implementation of eCall. By 2015, all new cars will be required to have M2M technology that allows their car to automatically notify the nearest emergency center when the driver has been in a crash.

The cars will be required to send a 'minimum set of data' to the emergency services including the exact location of the crash site, time of incident, and the direction of travel. As a result of this technology response times will improve by up to 60 percent in built up areas, and many more lives will be saved.
There are two options for implementing this mobile technology; firstly the tethered phone option. This would enable the eCall system to operate from the SIM that is inside of the consumer's mobile phone which would be 'tetheredí to the vehicle via Bluetooth or USB connection. The other is the embedded SIM, where the card is fitted inside the vehicle and connects automatically when an impact is detected.
The EU Commission strongly recommends the latter option since the tethered approach only works if the driver remembers to connect their phone (typically via USB, WiFi or Bluetooth) and their battery is charged. The driver also has to ensure the phone is with him or her at all times. An embedded SIM removes this uncertainty and will lead to more consistent responses. Many people within the industry are predicting that the EU Commission will soon make the embedded SIM mandatory.
Now the car industry is much more developed and that can be confirmed from various car models of different car brands. Now a days, car models are available in the market with lot more features and applications. The concept of Smart car now really working well and Smart cars are getting more populoarity these days. These are having the facilities of car infotainment helping the car operator to find the proper route and also to stay connected with the traffic control system. Smart car technology is definitely working well for the people. Car parts replace also very necessary for the car users when they are not working properly or damaged. People should be more careful while running their car on the roads.
