In 1998, the U.S. Congress enacted the transportation equity act for the 21st century [TEA98], which directed the Federal Communications Commission (FCC) to consider the spectrum needs “for the operation of intelligent transportation systems, including spectrum for the dedicated short‐range vehicle‐to‐wayside wireless standard.” In the United States, the 75‐MHz spectrum between 5.850 and 5.925 GHz is referred to as 5.9 GHz dedicated short‐range communications (DSRC). It is often necessary to specify 5.9 GHz when referring to DSRC to differentiate the new spectrum from the older 900 MHz band of the same name, used for electronic toll collection. The European Union (EU) also recognized the importance of a dedicated spectrum for ITS. The European DSRC spectrum is structured into five 10‐MHz channels, as opposed to the seven 10‐MHz channels allotted to DSRC in the United States. Vehicle‐to‐vehicle (V2V) safety communications are not an officially intended usage of DSRC technology in Japan.
