Device and method for inhibiting coexistence interference of WiMAX and WiFi

Abstract

The invention discloses a device and a method for inhibiting coexistence interference of WiMAX and WiFi. When a user receives radio-frequency signals of a wireless network by the device, a WiMAX filter module filters WiFi radio-frequency signals received by a WiMAX antenna, WiMAX radio-frequency signals are converted into the WiFi radio-frequency signals, and a WiFi filter module filters out-of-band interfering signals of the WiFi radio-frequency signals which is then sent to the user by a WiFi antenna; when the user sends the radio-frequency signals to the wireless network by the device, theWiFi filter module filters the WiMAX radio-frequency signals received by the WiFi antenna, the WiFi radio-frequency signals are converted into the WiMAX radio-frequency signals, and the WiMAX filter module filters the out-of-band interfering signals of the WiMAX radio-frequency signals which is then sent to the wireless network by the WiMAX antenna, thus reducing the interference between WiMAX and WiFi, increasing the data transmission rate and avoiding waste of frequency spectrum resources.

Description

technical field [0001] The invention relates to an interference suppression technology in a wireless network, in particular to a device and a method for suppressing coexistence interference of WiMAX and WiFi when WiMAX and WiFi coexist. Background technique [0002] World Interoperability for Microwave Access (WiMAX, World Interoperability for MicrowaveAccess) is a metropolitan area network technology based on the 802.16 series: 802.16d, 802.16e wireless standards, operating frequency bands are 2.3GHz, 2.5GHz and 3.5GHz, a The base station can provide a maximum downlink data transmission rate of 40Mbps for multiple fixed users within a radius of 3 to 10 kilometers, and provide a maximum downlink data transmission rate of 15Mbps for multiple mobile users within a radius of 3 kilometers. The biggest advantage of WiMAX It covers a wide working distance and allows use in mobile environments such as cars and cruise ships. [0003] Wireless local area network (WiFi, Wireless Fide...

AI Technical Summary

Problems solved by technology

In view of the above analysis, when WiMAX and WiFi coexist, it is easy to cause mutual interference between the radio frequency signals between WiMAX and WiFi, thereby greatly reducing the data transmission rate

[0005] In the prior art, the method of reducing the frequency band used by WiMAX or WiFi is usually used to expand the frequency band interval between the two, and minimize the interference of radio frequency signals between WiMAX and WiFi. For example, the frequency band used by WiMAX is limited to 2525MHz-2690MHz. Or limit the frequency band used by WiFi to the range of 2400MHz-2452MHz; however, although the above method can reduce the mutual interference between the two radio frequency signals, it causes a lot of waste of spectrum resources
