Evaluating the Effectiveness of a Partial Download Function for Automobiles 2003-01-0137

It is obvious that the quality of telematics services depends in particular on the radio wave environment of the cellular phones used as the communication infrastructure. There is a need to develop the technological capabilities for enabling users to enjoy stable communication without being conscious of changes in the surrounding radio wave environment. As one solution to this problem, this paper proposes a partial download function that divides the desired content data into smaller quantities for transmission and also selects areas with a good radio wave environment for downloading data while suspending communication in places where reception is poor. The results of driving tests are presented to demonstrate the effectiveness of this partial download function.
