Wireless mesh network system

Abstract

The invention discloses a wireless mesh network system. The system comprises a plurality of wireless mesh routers and terminal equipment which is accessed to a wireless network through the wireless mesh routers, wherein the wireless mesh routers are provided with wired Ethernet ports which can be directly connected to the Internet and two 802.11a / b / g wireless interfaces; one of the wireless interface is used for accessing the terminal equipment in the coverage area of the wireless mesh routers, while the other wireless interface is configured to form a return connection with the adjacent wireless mesh router; and at least one wireless mesh router is directly connected to an external Internet network through the Ethernet port. By utilizing the wireless mesh network system provided by the embodiment of the invention, forwarding nodes which should be passed when the terminal equipment is accessed to the network are reduced, and the complexity of network construction is reduced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a wireless mesh network system. Background technique [0002] In recent years, WLAN (Wireless Local Area Networks, wireless local area network) has developed rapidly in the field of wireless access. According to its huge data transmission rate, WLAN is also considered to be a part of 3G or post-3G mobile data communication. main competitor. However, WLAN also has its shortcomings, the most important of which is that the coverage of AP (Access Point, access point) is relatively limited. To provide wireless coverage in a relatively large area, it is necessary to configure multiple This access point must be connected to the gateway device through a cable, which increases the cost of building a WLAN-based public broadband network and limits the flexibility of networking. [0003] Publication No. CN1832461A discloses a wireless mesh network system, such as figure 1 As shown, ...

Problems solved by technology

[0004] However, in the above-mentioned wireless mesh network system, the gateway MGW and the access point MAP are separated, the gateway MGW only has wired access capabilities, and cannot directly provide wireless access functions for terminals; although MAP nodes can provide terminal equipment Wireless access function, but it cannot be directly connected to the Ethernet, and must be connected to the Internet wired network through the MGW, which will inevitably increase the forwarding nodes that the terminal must pass through to access the Internet, and increase the delay and signal attenuation of the terminal device accessing the Internet. reduce network bandwidth

Moreover, this networking method involves two different devices, MGW and MAP, which will inevitably increase the complexity and cost of networking.
