Problems solved by technology

[0005] However, due to the asymmetry of the CTC channel, CTC technology cannot achieve two-way symmetrical communication
Specifically, although packet-level CTC (cross-protocol communication at the data packet layer) can realize two-way communication, the asymmetric transmission power leads to an extremely asymmetric communication range
For example, the maximum transmission power of WiFi can reach 20dBm. When sending data packets from WiFi to ZigBee, the characteri

Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0033] In the prior art, cross-protocol communication technologies are mainly divided into two categories: physical-level CTC (cross-protocol communication at the physical layer) and packet-level CTC (cross-protocol communication at the data packet level).

[0034] The cross-protocol communication of the physical layer simulates a signal similar to that of the receiving end at the sending end, and generates a data packet compatible with the receiving end. Represented by WEBee, by ch...

Abstract

The embodiment of the invention provides a symmetric cross-protocol communication method and device for an asymmetric channel. A set of target CTC channels comprises overlapped CTC channels, namely, the total frequency band range of all the target CTC channels covers the frequency band range of the overlapped CTC channels; in cooperation with a chip sending mode of the method, data is sent by using four overlapped channels of a ZigBee end and a WiFi end; even if the data noise of part of channels is very high, data identification can also be carried out through data in other channels; CTC communication from the ZigBee end to the WiFi end is achieved, the utilization rate of overlapped CTC channels can be increased, the data transmission distance from the ZigBee end to the WiFi end is increased, and it is possible to establish symmetric CTC on asymmetric CTC channels.

Description

technical field [0001] The present application relates to the technical field of communication, in particular to a symmetrical cross-protocol communication method and device for asymmetric channels. Background technique [0002] The Internet of Things technology depicts the future grand plan of the Internet of Everything. Any independently addressable object can be integrated into people's lives through network interconnection, providing people with intelligent and convenient services. The Internet of Things technology has received more and more attention in the application field, and wireless network technology, which is one of the core technologies of the Internet of Things, has also developed rapidly. The wireless network protocols represented by ZigBee (Zifeng), Bluetooth (Bluetooth), and WiFi (Wireless Fidelity) were proposed according to different application requirements, and then continued to develop in their respective application fields. The wireless sensor networ...
