The Battle of Technologies or the Battle of Business Models? [Connected Vehicles]

There has been heated debate about the 5.9-GHz frequency band dedicated to cooperative intelligent transportation systems (C-ITSs) [1]. Spectrum is limited, and the free bands at 2.45 GHz are becoming crowded. Because of this, operators in the European Union seek access to the band for fifth generation (5G), while, in the United States. Wi-Fi wants access to the band. However, 5G is not yet fully defined, implying that it may or may not include Wi-Fi. The C-ITS technology, termed dedicated short-range communications (DSRC) in the United States and ITSG5 in Europe, is standardized but not deployed.
