Problems solved by technology

However, since this method involves the modification of the WiFi protocol, the implementation is relatively complicated, the cost is relatively high, and the response speed is slow
If the ZigBee service already exists in reality, the intervention of the WiFi service at this time will cause errors in ZigBee data transmission

Embodiment Construction

[0033] figure 2 It is a working flowchart of a method for reducing mutual interference between ZigBee and WiFi in the same device according to an embodiment of the present invention.

[0034] The present invention provides a method for reducing mutual interference between ZigBee and WiFi in the same device. The coordination service of ZigBee module and WiFi module parameters is configured in the same device. When the system of the device starts one of the ZigBee and WiFi services , detect whether another service has been started, if the other service has been started, the system selects the physical channel of the one service to avoid the physical channel of the other service, if the other service If the service is not started, the system will automatically select the physical channel of the service. Because in the same device, the working status of each module is known, the host can easily obtain the working information of each module, and carry out corresponding coordinati...

Abstract

The invention provides a method of reducing mutual interference between ZigBee and WiFi in same equipment. ZigBee module and WiFi module parameter coordination service is configured in the same equipment. When the equipment starts one business in ZigBee and WiFi, whether the other business is started is detected; if the other business is started, the system chooses a physical channel of a certain business so as to avoid a physical channel of the other business; and if the other business is not started, the system automatically selects the physical channel of the service. Through coordination on physical channels of the ZigBee module and the WiFi module, mutual interference between the ZigBee module and the WiFi module can be ensured to be totally avoided, and as modification of an agreement is not involved, realization is extremely simple, the setting speed is fast, the mutual interference problem between the ZigBee module and the WiFi module can be solved, and communication reliability is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for reducing mutual interference between ZigBee and WiFi in the same device. Background technique [0002] With the development of science and technology, compared with the traditional communication equipment limited by wired connection, the more convenient, fast and flexible wireless network has been developed rapidly. Wireless network communication technologies such as WiFi and ZigBee are more and more widely used in daily life. [0003] WiFi is a wireless network technology based on the IEEE802.11 standard. It is one of the most popular network protocols in daily applications. It is deployed in offices, homes, entertainment and even outdoor areas in cities. The WiFi protocol works in the 2.4GHz Industrial Scientific Medical (ISM) frequency band. ZigBee is a short-distance, low-power, wireless personal area network protocol based on the IEEE802.15.4 protocol. ...
