Query: On the Feasibility of 4.9 GHz Public Safety Band as Spectrum Option for
  Internet of Vehicles   There is an unprecedented impetus on the advancement of internet of vehicles
(IoV). The vehicle-to-everything (V2X) communication is well acknowledged as
the key technology in constitution of the IoV. Nevertheless, the spectrum for
V2X communication is undergoing a massive change in the United States: a
majority of the bandwidth has been reallocated to Wi-Fi leaving even less than
a half of the bandwidth for V2X. This motivates investigation of other
candidate spectrum bands for operation of V2X communication as an urgent effort
to guarantee efficient operations of IoV. To this line, this paper studies the
feasibility of sharing the 4.9 GHz public safety band between the incumbent
systems and V2X users.
