Dual-band wireless router and data transmission method thereof

Abstract

Embodiments of the invention provide a dual-band wireless router and a data transmission method. When the dual-band wireless router respectively transmits data to the respectively connected at least one electronic device through two frequency bands, one electronic device is selected from each frequency band and one of the two selected electronic devices that has a higher network usage priority is determined with regard to the data transmission rate; and when the data transmission rate between the dual-band wireless router and the electronic device having the higher network usage priority is less than a threshold, the dual-band wireless router increases the signal power of one frequency band to which the electronic device having the higher network usage priority and reduces the signal power of the other frequency band. The scheme disclosed in the embodiments of the present invention achieves that when the dual-band wireless router work in the two frequency bands simultaneously, influence on the signals between the frequency bands is reduced, so as to make the wireless transmission more practical.

Description

technical field [0001] Embodiments of the present invention relate to the field of wireless communication, and in particular to a dual-band wireless router (WirelessRouter) and a data transmission method thereof. Background technique [0002] A wireless router is a combination of a simple access point (Access Point, AP) and a broadband router. It is a router with a wireless coverage function, which is mainly used for user Internet access and wireless coverage. [0003] The wireless router can be regarded as a repeater, which forwards the broadband network signal connected to the wall of the home to nearby wireless network devices through the antenna, such as laptops, mobile phones supporting wifi, tablets and all devices with WIFI function. [0004] Popular wireless routers on the market generally support four access methods: private line XDSL / CABLE, dynamic x Digital Subscriber Line (Digital Subscriber Line, xDSL), and Point to Point Tunneling Protocol (PPTP).

Problems solved by technology

[0014] With the development and maturity of WIFI technology, more and more wireless routers support 2.4Ghz and 5Ghz WIFI transmission in two frequency bands to meet more devices, but the distance between the antennas of wireless routers is relatively small, the WIFI of the two frequency bands When working at the same time, they will interfere with each other and affect the rate of wireless transmission.

[0015] The use of the network by electronic devices in the home is equal. As long as it is connected to the wireless router, the wireless router will convert the requested data and perform data transmission on the 2.4Ghz or 5Ghz WIFI network. This method will inevitably cause wireless network failure. Working at the same time, the signals of two frequencies interfere

For example, a mobile phone and a wireless router are using a 5Ghz WIFI network through a 5Ghz frequency band WIFI connection, but at the same time a computer is downloading data through a 2.4Ghz frequency band. The rate is affected by the 2.4Ghz band wireless of the computer and wireless router

[0016] Therefore, the existing dual-band wireless routers transmit wireless signals with the maximum power when the two frequency bands are working at the same time. have an impact
