Problems solved by technology

However, today's gateway products require small size and volume, and the stagger distance of antennas is limited, so the effect is not obvious
At the same time, WiFi is the transmission of large data volume and large bandwidth, while the data information transmitted by Zigbee is often small, and Zigbee is often interfered by WiFi.

Abstract

A method and device forcoexistence of Zigbee network and WiFi are disclosed, the device includes a Zigbee antenna module, WiFi antenna module and a control unit, the control unit is connected with theWiFi antenna module, the Zigbee antenna module is used for accessing the Zigbee data stream, the WiFi antenna module is used for accessing the WiFi data stream, the control unit is used for accessingthe Zigbee enable signal, and the control unit is used for controlling the disconnection and communication of the WiFi antenna module. The disconnection and communication of the WiFi antenna module is controlled by a control unit, the control unit is connected to the Zigbee enable signal. The communication of Zigbee network is detected by Zigbee enable signal. When Zigbee network communicates, WiFi antenna module can be disconnected and WiFi data communication can be interrupted to ensure that space is occupied by Zigbee signal, which solves the problem that Zigbee is disturbed by WiFi.

Description

technical field [0001] The invention relates to the technical field of computer communication, in particular to a method for coexistence of a zigbee network and a WiFi network and a device for realizing the method. Background technique [0002] Zigbee network is widely used as a common access method in the Internet of Things, and WiFi is currently a widely used access method for home terminals to connect to the Internet. The Zigbee+WiFi gateway can realize the access between Zigbee Mesh network and Wifi . Since both are in the 2.4-2.4835GHz ISM frequency band, as the channel resources become more and more crowded, how to improve the coexistence between Zigbee and other wireless standards is of great engineering value. [0003] The solution in the existing technology is usually to stagger the antennas used by the two in space, so that the isolation between the WiFi antenna and the Zigbee antenna is improved, thereby reducing the interference between the two. However, today'...
