Problems solved by technology

However, since the master node and the slave node need to communicate within a certain distance range, the transmission distance is short and the anti-interference ability is poor, so it is impossible to fundamentally solve the problem of long-distance and high-efficiency wireless communication.

Abstract

The invention provides a data communication initiating method. The method comprises following steps: sending a request data packet for building communication connection, wherein the data packet comprises a local address and a target address; receiving a confirmation data packet fed back by a target end, wherein the confirmation data packet comprises transmission path information, determining the optimum transmission path to the target end according to the transmission path information; and transmitting data through the optimum transmission path. The invention also provides a data communication relaying method, a data communication receiving method and a data communication initiating device, relaying device and receiving device. Through the mode, in adoption of the methods and the devices of the invention, the long distance and high efficiency wireless transmission can be realized.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method for initiating, relaying and receiving data communication and a device thereof. Background technique [0002] Bluetooth is a wireless technology standard that enables short-distance data exchange between fixed equipment, mobile equipment, and building personal area networks (using UHF radio waves in the ISM band of 2.4-2.485GHz). Bluetooth uses frequency hopping technology to divide the transmitted data into data packets, and transmits data packets through 79 designated Bluetooth channels, each with a bandwidth of 1MHz. Bluetooth is a packet-based protocol with a master-slave architecture. A master device can communicate with up to seven slave devices in the same piconet, and all devices share the clock of the master device. Packet switching is based on a base clock defined by the master running at 312.5µs intervals. In the simple case of single-slot pack...
