Embodiment Construction

[0022] In order to allow users to use wireless communication products more conveniently, wireless communication products with the function of integrating heterogeneous wireless signal transmission are gradually launched. For a wireless communication device that functions as a Zigbee coordinator and a WiFi access point (AP) at the same time, a WiFi antenna and a Zigbee antenna are installed inside.

[0023] According to the Zigbee specification, a Zigbee end device or router can use the Zigbee connection provided by the coordinator. For example, two Zigbee products, one is a Zigbee wireless communication device (router), and the other is a Zigbee terminal device (sensor) into a join process. After the two Zigbee products are successfully connected, it means that the two products can transmit data to each other through the Zigbee specification. Once the Zigbee terminal device is triggered, it can notify the Zigbee wireless communication device.

Abstract

The invention discloses a wireless communication device for transmitting and receiving heterogeneous radio-frequency signals. The wireless communication device comprises a first antenna, a second antenna, a first transceiver, a second transceiver and a controller. The first transceiver controls the first antenna through a first transceiving path to transmit and receive the first radio-frequency signals according to a first wireless communication standard. The second transceiver controls the second antenna through a second transceiving path to transmit and receive the second radio-frequency signals according to a second wireless communication standard. The wireless communication device and a terminal device are connected according to the second wireless communication standard to be in the joint process stage. The controller decreases the transmission power for transmitting the first radio-frequency signals in an adjustment mode or decreases the receiving sensitivity of the second radio-frequency signals in an adjustment mode.

Description

technical field [0001] The invention relates to a wireless communication device, and in particular to a wireless communication device for sending and receiving heterogeneous radio frequency signals. Background technique [0002] Since most countries regulate the radio wave spectrum, many wireless communication standards must use limited open frequency bands. For example, the operating frequencies of the ZigBee specification and the Wireless Local Area Network (WiFi) specification are both industrial / scientific / medical bands (Industrial Scientific Medical band, referred to as ISM). Since the frequency bands of the two specifications both fall on 2.4GHz, the ZigBee signal and the WiFi signal are likely to interact with each other. [0003] The method of reducing interference in the prior art is to adjust the working frequencies of the ZigBee signal and the WiFi signal, and keep the working frequencies of the ZigBee signal and the WiFi signal away from each other. For example...
