METHOD FOR UPDATING TERMIAL FIRMWARE AND OPERATING DATA USING WIRELESS COMMUNICATION BETWEEN TERMINALS

摘要

A method for updating a firmware of a terminal installed on a transport means without having to access a server installed on the garage of the transport means. The terminal is capable of downloading new firmware from another terminal installed on another transport means when the terminal is unable to access the server or when it is not recommendable to access the server. For this purpose, each terminal must be able to provide their own version information of the firmware they have.
