Abstract
The invention provides a wireless network signal transmission system, which comprises a mixer, a coaxial cable, a frequency divider and a duplex antenna. The mixer can mix wireless network signals and television signals, the coaxial cable is connected with an output end of the mixer, the frequency divider is connected with the coaxial cable and divides the wireless network signals and the television signals, and the duplex antenna is connected with an output end of the frequency divider and transmitting the wireless network signals. By the wireless network signal transmission system, the number of access points of the wireless network can be reduced, cost is reduced and frequency spectrum interference is avoided.
Description
Technical field
The present invention relates to a kind of wireless network signal transmission system.
Background technology
Along with the continuous development of radio network technique, dispose wireless network in the increasing family.In the prior art, conventional wireless network arrangement adopts the wireless network access point (AP) such as wireless router to realize often, and promptly each household family needs a wireless network access point, and cost is very high.In addition, under the situation of radio spectrum resources growing tension, wireless network access point of each household causes the interference between the wireless frequency spectrum easily, and the waste of frequency spectrum resource.
Summary of the invention
The technical problem that the present invention will solve provides a kind of wireless network signal transmission system, can reduce the quantity of wireless network access point, reduces cost, and avoids spectral interference.
For solving the problems of the technologies described above, the invention provides a kind of wireless network signal transmission system, comprising:
Wireless network signal and TV signal are closed the frequency mixer on road;
The coaxial cable that links to each other with the output of said frequency mixer;
Link to each other with said coaxial cable, with said wireless network signal and TV signal frequency divider along separate routes;
The duplexed antenna that links to each other with the output of said frequency divider, said wireless network signal is propagated.
Alternatively, said duplexed antenna links to each other with the output of said frequency divider through power governor.
Alternatively, said frequency divider and power governor are the lumped parameter lc circuit.
Alternatively, said power governor and said duplexed antenna integrate.
Alternatively, said duplexed antenna is gum cover omnidirectional duplexed antenna or dull and stereotyped directed duplexed antenna.
Alternatively, said wireless network signal transmission system also comprises: the wireless network access point that sends said wireless network signal.
Alternatively, said frequency divider comprises a plurality of frequency dividers that are distributed in a plurality of rooms.
Alternatively, said wireless network signal transmission system also comprises: link to each other, receive the television set of said TV signal with another output of said frequency divider
Alternatively, said coaxial cable is a cable tv coax.
Compared with prior art, the present invention has the following advantages:
In the wireless network signal transmission system of the embodiment of the invention; Wireless network signal and TV signal are closed the road and transmit through frequency mixer via coaxial cable; Adopt frequency divider to supply the user to use in the back along separate routes wireless network signal and TV signal at user side; The existing wired television coaxial cable transfers to different domestic consumers with wireless network signal in the conventional family thereby can utilize; Solved the shielding problem of wall, need not in each family, to arrange special-purpose Wi-Fi access point separately, helped the process that reduces cost, reduces maintenance, improves resource efficiency, solves the wireless frequency spectrum interference problem and promote the integration of three networks wireless signal.
Description of drawings
Fig. 1 is the structured flowchart of the wireless network signal transmission system of the embodiment of the invention.
Embodiment
Below in conjunction with specific embodiment and accompanying drawing the present invention is described further, but should limit protection scope of the present invention with this.
Fig. 1 shows the structural representation of the wireless network signal transmission system of present embodiment, comprising: wireless network access point (AP) 10, frequency mixer 11, coaxial cable 12, one or more frequency divider 13, duplexed antenna 14 and wireless device 15.
Wherein, wireless network access point 10 sends wireless network signal (like the WIFI signal etc.), is preferably powerful AP equipment, to improve signal quality.
After wireless network signal that frequency mixer 11 sends wireless network access point 10 and TV signal are closed the road, export coaxial cable 12 to through output.Wherein, TV signal can be cable TV signal, wireless television signal (like CMMB TV signal etc.).
The signal that coaxial cable 12 closes wireless network signal and TV signal after the road transfers to each family, for example in the room of a plurality of subscriber households in the same storied building.
All be furnished with frequency divider 13 and duplexed antenna 14 in the room of each subscriber household; Wherein frequency divider 13 is with closing the road signal along separate routes in the coaxial cable; Being about to wireless network signal separates from the signal that closes the road; Launch through duplexed antenna 14, the employed wireless device 15 of user (for example mobile phone, panel computer etc.) can receive the wireless network signal that emits, final realize with wireless network access point 10 between communicate by letter.
In the present embodiment; Duplexed antenna 14 links to each other with an output of frequency divider 13 through the power governor (not shown); Preferably, this power governor and duplexed antenna 14 integrate, and are used to regulate the power of isolated wireless network signal; Make its technical indicator that satisfies wireless transmission, for example satisfy the specification requirement of WIFI wireless transmission.
In addition, frequency divider 13 can also make user's television set can pass through this output received television signal through another output output in the back TV signal along separate routes.
To sum up; Carry out the transmission of wireless network signal and TV signal through existing wired television coaxial cable among the domestic consumer in the present embodiment; Utilize the signal shunt after frequency divider will close the road after arriving subscriber household; Be sent to duplexed antenna and television set respectively, make the domestic consumer when televiewing, can the wireless device access of radio network be surfed the Net.Through above-mentioned cloth net mode, can avoid new cable to insert in the user room, promptly do not need to set up again new cable, use one or a few high-power AP, existing limited television coaxial cable promptly capable of using carries out the covering of wireless network signal.In addition, carry at television set under the situation of wireless access function, can also realize video on demand.
Though the present invention with preferred embodiment openly as above; But it is not to be used for limiting the present invention; Any those skilled in the art are not breaking away from the spirit and scope of the present invention; Can make possible change and modification, so protection scope of the present invention should be as the criterion with the scope that claim of the present invention was defined.
