Nowadays in our society, the presence of electronic devices, such as GPS systems and Wireless LAN is increasing. These devices are not only popular because they are fashionable, but they are efficient and can improve time management. Sometimes these devices can also be used to make our lives safer. This is the case of Vehicular Networks.
Traffic problems are occurring more and more as time goes by, and the car is becoming one of the places where people spend a lot of time both for work and entertainment. Therefore the necessity of feeling comfortable and safe in the car is becoming more and more important. With the Vehicular Network, cars will certainly circulate in a more secure way by communicating with each other and sharing information about their surroundings, hence the number of car accidents and of road deaths will decrease.
The thesis explores this new kind of Network and has two main aims. The first aim is to analyze the results from a campaign of "real world measurement" for infrastructure-to-vehicle communication and to find how different parameter settings affect the value of the minimum required signal-to-noise ratio value, in order to obtain a frame error ratio less than 0.1. The second aim is a sequence of laboratory measurements, in order to understand how the signal power is measured from the devices employed in the real world measurements. The obtained information about the most efficient parameter settings can be used, in order to improve vehicluar communications. Moreover the achieved results from the laboratory measurements will help to get a better understanding of the behavior of the used vehicular transmitter and receiver.
