Signal processing method and wireless network access equipment

Abstract

The embodiment of the invention provides a signal processing method and wireless network access equipment, and the signal processing method is applied to the wireless network access equipment. The the method comprises the following steps that: the wireless network access equipment detects whether first adjacent channel interference exists between a first channel used by an accessed wireless local area network and a current working frequency band of a cellular network accessed by the wireless network access equipment or not; wherein the first adjacent channel interference is interference generated when a frequency band of a channel used by the wireless local area network is adjacent to a working frequency band of a cellular network; and if the first adjacent channel interference exists and a channel switching condition is satisfied, the wireless network access device switches the currently used first channel to a second channel of a wireless local area network, and the first adjacent channel interference suffered by the second channel is smaller than that of the first channel. By switching the first channel and the second channel, the first channel is isolated from the current working frequency band, so that mutual interference between a wireless local area network and a cellular network is avoided.

Description

【Technical field】 [0001] The embodiments of the present application relate to the technical field of wireless communication, and in particular, to a signal processing method and a wireless network access device. 【Background technique】 [0002] The cellular network (Cellular Network) can also be called the mobile network (Mobile Network). A cellular network is a mobile communication hardware architecture. Common cellular network types include: Global System for Mobile Communications (GSM) network, 3G network, 4G network, 5G network, etc. [0003] Wireless Local Area Network (WLAN) refers to a local area network that does not use any wires or transmission cables. Wireless LAN uses wireless electromagnetic waves as the medium for data transmission. The common standard for wireless LAN is the IEEE 802.11 standard. [0004] In actual user application scenarios, users can use terminal devices to access the Internet through cellular networks or wireless LANs, but the performanc...

Problems solved by technology

However, both the cellular network and the wireless local area network use wireless electromagnetic waves for communication, and they need to compete for the use of the air interface (air interface) environment at the same time, resulting in the situation that the working frequency band of the cellular network and the working channel of the wireless local area network are adjacent to each other. Mutual interference of LAN signals

Mutual interference between the cellular network and the wireless LAN signal will reduce the user experience of using the wireless LAN network and affect the communication quality of the cellular network
