Description
Technical field
The utility model relates to wireless communication technology field, particularly a kind of WAP (wireless access point) of Wireless MESH network.
Background technology
In Wireless MESH network, the main effect of WAP (wireless access point) (AP) is that wireless network is inserted core net, secondly each terminal equipment that links to each other with wireless router is linked together, make the terminal equipment that wireless network card is housed to share the resource of core net by AP.Traditional MESH network can only provide limited autgmentability, and one or more new AP adds fashionablely in network, need carry out the manual of each equipment and be provided with, and is very inconvenient.
In addition, in order to have exploitativeness, Wireless MESH network must be the network of low time delay, for Ingress provides independent wireless bandwidth link (being similar to full duplex is connected) with the Egress backhaul traffic.
In the single-frequency scheme, all information are all on same channel, AP only uses a channel, this channel is shared by wireless client and backhaul traffic (transmitting between AP), and when more AP joined in the network, the bandwidth that is used for backhaul traffic will occupy more and more higher ratio, only stay seldom a part of capacity to give wireless client, can not transmit and receive data simultaneously, and when another AP was transmitting in its coverage, this AP can not send data.
In the double frequency scheme, a channel is used for connecting wireless client specially, and another channel is used for carrying out the wireless backhaul transmission specially---and Return Channel is shared by Ingress and Egress flow simultaneously.Thus, wireless client traffic will obtain the improvement of some, but the performance of the whole network is still undesirable owing to the bottleneck problem of backhaul.

The wireless signal of described first wireless module or second wireless module covers other WAP (wireless access point) and terminal equipment in this network in wireless mesh network, support automatic discovery feature, described automatic discovery feature comprises the position of other wireless modules in the described WAP (wireless access point) of automatic discovery, automatically find the position of other modules, and determine described WAP (wireless access point) to adopt wired mode or wireless mode to be connected automatically with outside cable network.
Described first wireless module comprises a finite state machine (FSM, Finite StateMachine) module, realizes automatic discovery feature by described finite state machine module.Described automatic discovery feature comprises the position of other wireless modules in the described WAP (wireless access point) of automatic discovery, finds the position of other modules automatically, and determines described WAP (wireless access point) to adopt wired mode or wireless mode to be connected with outside cable network automatically.
Described first wireless module uses 802.11 different agreements with described second wireless module, and wherein a side adopts the 802.11a agreement, and then the opposing party uses the 802.11b/g agreement.
Owing in this WAP (wireless access point), comprise two wireless modules at least, can there be a wireless module can be used for the terminal equipment that other access points and this WAP (wireless access point) under the present networks cover is connected to other Wireless MESH networks, like this, the terminal equipment that moves under present networks is when entering other Wireless MESH networks, do not need to login again and carry out actions such as mobile context switching, directly second wireless module by WAP (wireless access point) in the former network is connected with other Wireless MESH networks, therefore effectively improve the mobility in the Wireless MESH network, ensure the continuity when network switches.
Each WAP (wireless access point) of the utility model is used the dedicated wireless link interface of 2.4GHz, 4.9GHz and three channels of 5.8GHz at least, one of them channel is used for the flow of client, second channel is used for Ingress wireless backhaul flow, and the 3rd channel is used for Egress wireless backhaul flow.The utility model scheme is compared with single-frequency or double frequency scheme good performance is provided, because each link all is operated in independently on the channel, special-purpose back haul link (Backhaul) can transmit and receive data simultaneously, support the combination of multiple wireless coverage and backhaul, can improve the service efficiency of system effectively a plurality of frequencies.
