What Is The 802.11P [Protocol] In DSRC Communication Technology?

DSRC communication or short-range wireless communication technology enables vehicles and other users on the roads to communicate with each other and therefore it is popularly known as a dedicated communication technology which can be used over the short range. Much has been spoken about this technology as people are led to believe driving will become safer and even provide them a number of benefits without making any attempts to explain that DSRC communication would not be a success unless it was also supported by 802.11P which has also been identified as the primary mechanism for allowing communication between vehicles and infrastructure.


The introduction of new technologies is always exciting and most people just watch out for the final results without ever looking into the finer points which support the technologies and make them effective. Researchers have made several changes to the features of the 802.11P devices to make them compatible with the DSRC communication system.


The Internet has the potential to scare every individual because of numerous scams and unscrupulous activities which can be observed or are reported. 802.11P is also an Internet protocol which is capable of transmitting information anonymously in order to improve the efficiency of the traffic system and provide safety to the flow of traffic and prevent accidents. The network which is formed by 802.11P devices is identified as Vanet. The system provides information to the driver of the vehicle without disclosing his or her details to any other drivers or infrastructure which has been equipped with the DSRC communication technology.


As DSRC communication is a wireless technology it also needs the 802.11P protocol in order to enable the communication between vehicles, infrastructure, and people. The DSRC technology would not be worth or perhaps even function less effectively with other protocols which are also available. The department for intelligent transport systems has specifically determined that the DSRC communication technology needs a dedicated spectrum in the region of 75 MHz in the 5.9 GHz band and the same was allocated to the ITS to manage the technology of DSRC.


DSRC communication makes it easy for drivers to see around blind spots which are the sensors are unable to pick up and the technology is optimized to be mobile even in places with many obstructions while handling the changing environments at speeds which can exceed 500 km per hour. Researchers have determined that a range of 1 km is generally achievable by drivers using this technology.


DSRC communication along with 802.11P is capable of ensuring a general interoperable safety standard for vehicles of all types regardless of their size, model or make in order to help to prevent crashes, reduce congestion and to optimize the flow of traffic. DSRC is proving to be the key foundation for the vehicle to vehicle and vehicle to infrastructure safety because it enables effective communication by providing connectivity to users of the road which have until this moment never been linked to each other on a large scale.


People can very well assume they will see a vast improvement in the way vehicles and traffic movement is managed in the future simply because D SRC communication is being made available to them by the US intelligent transport system. However, people are advised to understand the also need to invest in technology such as 802.11P without which they are likely to encounter difficulties managing their vehicles with the use of DSRC communication technology. People must understand that both these technologies complement each other and also function at their best when they can support each other for maximum efficiency.
