Communication system, device and method

Abstract

The invention relates to a communication system and a communication method. The communication system comprises a first communication device and a second communication device. the communication distance between the first communication device and the second communication device is controlled by through a first wireless channel; data exchange is conducted by the first communication device and the second communication device through a second wireless channel; the first communication device comprises a radiocast sending module, a first main control module and various first wireless communication modules; and the second communication device comprises a radiocast receiving module, a second main control module and a second wireless communication module. The communication system and the communication method ensure that communication connection can be fast and automatically built between communication devices satisfying requirements of setting of the communication distances, data exchange can be conducted, a user does not need intervene in the accessing process, complex and fussy configuration operations of communication parameters of the user are avoided, using complexity is reduced, convenience of near field communication between the communication devices is improved and user experience is improved.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to a communication system, equipment and method. Background technique [0002] With the development of electronic information and network technology, in order to meet the needs of human work, life, study and entertainment, consumer electronic devices with different functions are constantly emerging, and the number and types of these consumer electronic devices owned by individuals are also increasing. For example, notebook computers, mobile phones, digital cameras, MID (Mobile Internet Devices), PMP (Portable Media Player), etc. In order to browse, edit, store, manage, and share data, it is often necessary to exchange data between consumer electronic devices, which is traditionally realized by using wired transmission methods such as USB. Now, more and more consumer electronic devices have integrated wireless communication modules, such as WIFI wireless communication modules, Blueto...

AI Technical Summary

Problems solved by technology

However, since wireless signals spread openly in space and the transmission distance is generally long, intruders can illegally access devices in hidden places without the physical security of wired connections, and device data security is facing challenges

In addition, to establish a connection and exchange data between two devices with a wireless communication module, a series of complicated settings need to be made between the devices, which undoubtedly increases the difficulty for users to exchange data between different devices and is not convenient.
