Patent ID: 10285101

Abstract:
Disclosed is a method of adjusting a data transmission rate between a vehicle and an access point (AP) as an embodiment of the present invention. The method according to an embodiment of the present invention may include receiving a signal broadcast from at least one AP near a vehicle, transmitting and/or receiving data to and/or from a predetermined AP at a first data transmission rate R0 on the basis of the received signal, receiving and storing signals broadcast from a plurality of APs near the vehicle in every predetermined period while the vehicle is moving, determining the number NT of APs having broadcast signals with strength greater than or equal to a threshold value among the signals received from the plurality of APs, comparing the number NT of APs to the number NT-1 of APs having broadcast signals with strength greater than or equal to the threshold value in a previous period, and determining a data transmission rate between the vehicle and the AP on the basis of a result of the comparison.
