Method for promulgating message between vehicles and devices

Abstract

A method and device for transmitting the audio and / or data information about upgrade, advertisement, searching, help, etc between cars features that each car is equipped with a bluetooth (or 802.11) device and all the bluetooth devices have a common password for allowing the log-on between cars to create links between them. The information can be transmitted from one car to another cars and in turn to other cars in cascade mode.

Description

technical field [0001] The present invention relates to a method and device for disseminating information between vehicles, especially a method and device suitable for a vehicle carrying a wireless communication device, capable of wirelessly disseminating a message to other vehicles through a viral transmission framework. Background technique [0002] At present, in addition to the use of radio for communication in the early days, the wireless communication of vehicles also has the use of vehicle-mounted mobile phones containing GSM modules or GPRS modules to carry out wireless transmission of voice or data data recently. [0003] However, the security of the early radio was not high; the later GSM module, or GPRS module, or even the future 3G module belongs to the long-distance communication architecture. In order to cover the entire communication range, the communication industry must comprehensively build a large number of bases in a large area In order to complete a wire...

Problems solved by technology

[0003] However, the security of the early radio was not high; the later GSM module, or GPRS module, or even the future 3G module belongs to the long-distance communication architecture. In order to cover the entire communication range, the communication industry must comprehensively build a large number of bases in a large area In order to complete a wireless communication network, the construction cost is high and the construction time is long, which makes the communication industry spend a lot of money, and its communication range is still limited to the range of the base station.

[0004] In addition, the communication rate of the above-mentioned existing long-distance communication structure is high. Even if the consumers are close at hand, consumers still have to pay the high long-distance communication rate, which is really unreasonable. In turn, it limits various commercial application opportunities and hinders other non-commercial developments. It cannot be widely used in all walks of life, which is not ideal.
