The WiFi base station antenna system can supply a plurality of independent non-interfering channels simultaneously and ensures that the data information transmission and the service of images and voice can be optimally transmitted on the individual independent channel without being interfered by other information.
Description
Technical field
The present invention relates to a kind of base station antenna system, particularly relate to a kind of WiFi base station antenna system that a plurality of non-interfering channels can be provided simultaneously.
Background technology
Traditional WiMAX WiFi base station though there are many channels (channel) to switch in same frequency, for example has 11 to 13 channels to switch in 2.4GHz frequency (802.11b and 802.11g), then can only provide single channel at one time.If will enable a plurality of channels simultaneously in order to increase bandwidth, meeting produces the phase mutual interference and makes the base station functions paralysis between the channel.Unless special breakthrough is arranged, traditional WiFi base station can only make with single channel in a frequency.If different frequencies, for example 2.4GHz and 5GHz, then mutual interference can simultaneously and be used by the antenna isolation of different frequency.
General wireless telecommunication system is in order to solve the channel interference problem, make the base station can use a plurality of channels simultaneously to increase the bandwidth of communication, communication system on artificial satellite and ground etc. for example, general all use the channel filter to obtain enough isolation to avoid phase mutual interference between channel, but cost is very expensive.In the WiFi system,, therefore can't accept expensive channel filter, and the channel filter can't reach enough isolation cheaply because use a large amount of base stations., traditional WiFi system can obtain rational system power and rational cost so can't only relying on the channel filter.
Just in the multi-media radio communications market of develop rapidly, 3G can't provide enough bandwidth to be fact proved at present, even this point has indicated that 4G in the future still can't satisfy the huge bandwidth demand in multimedia market.And the WiFi system yet can't provide enough cheap bandwidth at present.So need break through present situation technically, make the WiFi base station reach: (1) provides multichannel simultaneously; (2) each channel can provide at least 54 million bandwidth; (3) interference problem between the solution adjacent channel.Only in this way could alleviate the bottleneck of multi-media radio communications market bandwidth.
The demand of multi-media radio WiFi communications market has the demand of very high-quality to QoS (service quality) except the requirement of bandwidth.In multimedia application, except a large amount of transmission of Internet data message, to image and voice quality require high.But these the three kinds required processing environments of service are different with conditionally complete, unless there is the good QoS ability can these three kinds services of separate processes otherwise the multimedia quality is a big bottleneck.The base station of present traditional WiFi system can only provide a channel to handle three kinds of services of different nature simultaneously, so just can't satisfy the QOS demand in the wireless transmission process.
Summary of the invention
The purpose of this invention is to provide a kind of WiFi base station antenna system that a plurality of non-interfering channels can be provided simultaneously, the channel that this system can provide a plurality of complete independences not interfere with each other simultaneously also makes the service of data information transfer, image and voice independently optimizing transmission separately on the channel and not disturbed by other types information.
Technical scheme of the present invention is:
A kind of WiFi base station antenna system that a plurality of non-interfering channels can be provided simultaneously, comprise the Wifi base station, it also comprises n channel filter, the corresponding channel filter of each channel of described Wifi base station, the employed channel filter of each channel are used to provide 20～30dB isolation to come to isolate with adjacent channel; N circular polarization aerial, the axial ratio of each circular polarization aerial are 1～2dB; Be provided with a contrapolarization controller between each is to immediate circular polarization aerial, described contrapolarization controller is used to make this to the circular polarization aerial contrapolarization; Be provided with n WiFi network interface card in described Wifi base station, each WiFi network interface card is connected with a circular polarization aerial behind a channel filter.
The present invention has following beneficial effect:
In technical scheme of the present invention, the employed channel filter of each channel is used to provide 20～30dB isolation to isolate with adjacent channel, therefore, compare with the isolation of traditional need 50 to 60dB such as deep space satellite communication, channel filter cost of the present invention is very low; The present invention has adopted circular polarization aerial, compares with traditional linearly polarized antenna, and the axial ratio of circular polarization aerial is 1～2dB, and isolation effect is very good; By being provided with a contrapolarization controller between each is to immediate circular polarization aerial, the contrapolarization controller is controlled this to circular polarization aerial and make their contrapolarizations.Promptly, the present invention combines by the signal isolation features of above-mentioned channel filter, the contrapolarization signal isolation features of circular polarization aerial and the signal isolation features of the space length between arbitrary circular polarization aerial and the immediate with it circular polarization aerial, and the present invention can reach the base station antenna system that a low cost is provided and realizes easily.Thereby the present invention can make the WiFi base station that several independent fully channels that does not interfere with each other are provided simultaneously, thereby can increase the whole system bandwidth; And also make the service of data information transfer, image and voice independently optimizing transmission separately on the channel and not disturbed, thereby can provide optimized service quality by other types information.
