Autonomous cars are growing in commercial popularity. This growth will cause the need for wireless transmission of data to these cars to not only aid the software to drive more efficiently, but to also entertain the driver. Currently, autonomous vehicles are allowed to transmit using the band specified by the IEEE protocol 802.11p. While vehicles can transmit data using the 5.9 GHz band (5.850-5.925 GHz), the band may not support wireless transmission of media to vehicles’ infotainment systems. As people are freed from the task of driving, the demand for in-car internet connect applications, such as Netflix or Skype, will grow. This requires an alternative. With the switch from analog to digital television, the government has vacated the analog TV bands. This bandwidth provides a possible solution to the limitations of 802.11p transmissions. The vacated space is called TV white space. One proposed use of this white space is to provide Wi-Fi. This idea has been called White-Fi. According to our research, researchers have measured whether the specific frequencies are occupied but do not provide the unprocessed data. With this in mind, we measure the occupancy of the TV white space and we simulate how a network using this band would perform under the multiple scenarios of everyday driving.
