Abstract
The invention relates to a network transmission method, in particular to a method for realizing wifi long distance transmission by catenulated connected network. The method for realizing wifi long distance transmission by catenulated connected network comprises the following steps: a) wired connection is provided between two wireless routers to form a sub-network which serves as a communication cell; b) two wireless routers in the communication cell respectively build wireless bridging with superior and subordinate communication cells, one wireless router receives from and sends data to the superior communication cell, and the other wireless router receives from and sends data to the subordinate communication cell; c) a plurality of communication cells are connected in an end-to-end manner to form a catenulated transmission network so as to realize the wifi data long distance transmission. The communication cell device features low cost and convenient installation and is suitable for wireless monitoring in long and narrow route-type zone, the signal does not attenuate stepwise, and wifi data communication of any distance can be realized.
Description
Technical field
The present invention relates to network transfer method, be specially the method that realizes the wifi long-distance transmissions by the continuous network of chain.
Background technology
Existing wifi wireless communication distance is shorter, the open field communication range also only has about 300 meters, but in actual applications, usually there is the long and narrow scope of dozens or even hundreds of kilometer to need the network coverage, as the wifi signal covering of oil pipeline, electric power transmission network, highway, subway line etc.The method that improves the wifi wireless communication distance at present has two kinds: first kind is to adopt directional antenna, and behind the use directional antenna, communication distance can be brought up to from 300 meters of original omnidirectional antenna about 2000～3000 meters; Second kind is the mode that adopts the wireless repeater relay, promptly adopt a plurality of wireless repeaters to do the forwarding of signal, in this manner, when doing signal forwarding, do not do by repeater the verification and the examination of data correctness, caused no matter useful signal still is a noise signal and all transmitted simultaneously, the noise data of the voluminous more life of progression of process repeater is many more, noise signal amplifies step by step, thereby cause transmission bandwidth and signal stabilization sharply to descend, unavailable until data, testing the result factually shows, adopt trunking scheme to improve the wifi wireless communication distance, multipotency is accomplished 6 grades of relayings, and the transmission range maximum can reach about 8 kilometers, and existing two kinds of realization technology are not all accomplished tens of kilometers wifi transfer of data.
Summary of the invention
The present invention provides a kind of method that realizes the continuous network realization of the chain wifi long-distance transmissions of the remote wifi transfer of data more than tens kilometers just at above technical problem.
Concrete technical scheme of the present invention is as follows:
Method by the continuous network realization of chain wifi long-distance transmissions may further comprise the steps:
A) adopt two wireless routers to form a sub-network by wired connection, with this sub-network as a communication unit;
B) two wireless routers in the communication unit are set up wireless bridge joint with the superior and the subordinate communication units respectively, and wireless router and higher level's communication unit carry out data transmit-receive, and another wireless router and subordinate's communication unit carry out data transmit-receive;
C) several this communication units join end to end, and form the transmission network of a chain, thereby realize the long-distance transmissions of wifi data.
Wireless router in the communication unit adopts the directional antenna of two different azimuth, promptly communicates by letter with the communication unit of the superior and the subordinate respectively by two antennas, and each antenna all possesses and independently receives sending function.
Technique effect of the present invention shows: the communication unit equipment cost is low, easy for installation, relatively be suitable for using on the wireless monitor in the long and narrow zone of route class signal can not decay step by step, can realize the wifi data communication of any distance, no longer be subjected in the past the hundreds of rice of scheme or the restriction of a few km distances, bandwidth can obviously not reduce yet, and avoids the problem that noise data amplifies in the repeater relay transmission course.
Embodiment
The invention will be further described below in conjunction with embodiment
Embodiment:
Method by the continuous network realization of chain wifi long-distance transmissions may further comprise the steps:
A) adopt two wireless routers to form a sub-network by wired connection, with this sub-network as a communication unit;
B) two wireless routers in the communication unit are set up wireless bridge joint with the superior and the subordinate communication units respectively, and wireless router and higher level's communication unit carry out data transmit-receive, and another wireless router and subordinate's communication unit carry out data transmit-receive;
C) several this communication units join end to end, and form the transmission network of a chain, thereby realize the long-distance transmissions of wifi data.
Wireless router in the communication unit adopts the directional antenna of two different azimuth, promptly communicates by letter with the communication unit of the superior and the subordinate respectively by two antennas, and each antenna all possesses and independently receives sending function.
Can not decay step by step by the signal after the method for the continuous network realization of chain wifi long-distance transmissions, can realize the wifi data communication of any distance, no longer be subjected in the past the hundreds of rice of scheme or the restriction of a few km distances, bandwidth can obviously not reduce yet, and avoids the problem that noise data amplifies in the repeater relay transmission course.
