Description
Technical field
The invention belongs to signal fused access technology field, relate generally to a kind of local side apparatus and its implementation that realizes wire radio signal, WIFI signal, ethernet signal synchronous transmission.
Background technology
So far, cable TV network is all based on coaxial cable.China radio and television general bureau to the integration of three networks to the transformation at family based on coaxial cable, rather than directly Fiber to the home, mainly be because: laying expense costliness, the extensive technology of using is ripe not enough, the user terminal standard is ununified as yet, and the follow-up developments resistance of cable TV network is very big.Consider that based on these now for the transformation of the integration of three networks to the family, Chinese radio and television general bureau carries out on the basis of original coaxial cable.
EOC (Ethernet over Coax) transmission technology, it is based on the characteristics of cable TV coaxial net and the Ethernet connecting system that designs.The EOC transmission technology, utilized cable TV signal to use the high-end frequency of 45-860MHZ, the base-band data signal of Ethernet uses the low side frequency of 2-30MHZ, so both can transmit in same cable and be independent of each other, the Data Base band signal of Ethernet and TV signal are fed to by mixer on the distribution cable of former television network, deliver to the user together.At user side, by separator TV signal and data-signal to be separated, TV signal is delivered to television set, and data-signal is delivered to computer.Do not change the cable system of former TV distribution network like this, need not add category-5 cable in addition again, for the broadband access of cable TV coaxial net provides a kind of economical and practical technical scheme.
Wireless aps (Access Point) is a WAP (wireless access point), and it is the wireless exchange board that is used for wireless network, also is the core of wireless network.Wireless aps is the access point that the mobile computer user enters cable network, is mainly used in broadband home, inside, building and inside, garden, and typical range covers tens meters to rice up to a hundred, and major technique is 802.11 series at present.Most of wireless aps also have access point client mode (AP client), can carry out wireless connections with other AP, the coverage of extension network.
The WIFI wireless network is by AP(Access Point) and the wireless network formed of wireless network card.In open zone, communication distance can reach 305 meters; In the closure zone, communication distance is 76 meters to 122 meters, and convenient and existing wired ethernet is integrated, and the cost of networking is lower.The coverage of existing WIFI at home more and more widely, luxurious hotel, the mansion district, all there is the WIFI interface in the zone of airport and coffee shop and so on.But because the WIFI self-technique, there is the problem of difficulty through walls in WIFI.Because the barrier of area of space, make the WIFI signal weaker in a lot of application scenarios, coverage diminishes.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can realize the local side apparatus of wire radio signal, WIFI signal, ethernet signal synchronous transmission and utilize this equipment to realize the method that above-mentioned signal fused inserts.
Many signal fused insert local side apparatus, comprise rf input interface, RJ45 interface, frequency mixer, WAP (wireless access point), EOC module and radio frequency output interface.Rf input interface is connected with a signal input part of frequency mixer, and the RJ45 interface is connected with the signal input part of WAP (wireless access point), and a signal output part of WAP (wireless access point) is connected with another signal input part of frequency mixer; Another signal output part of WAP (wireless access point) is connected with the signal input part of EOC module, and the signal output part of EOC module is connected with another signal input part of frequency mixer; The mixer signal output is connected with radio frequency output interface.
From the wire radio signal of rf input interface input, after the frequency mixer mixing, realize synchronous transmission from the WIFI signal of WAP (wireless access point) output and the ethernet signal of EOC module output.
Utilize these many signal fused to insert the method that local side apparatus realizes that many signal fused insert, comprise the steps:
The wire radio signal of step 1. coaxial wire transmission is transferred to frequency mixer through rf input interface.
The WIFI signal of step 3. WAP (wireless access point) is transferred to frequency mixer by connecting line.
The ethernet signal of step 4. WAP (wireless access point) is transferred to the EOC module by connecting line.
Step 5.EOC module is transferred to frequency mixer by connecting line with ethernet signal.
Signal after step 7. mixing is exported by radio frequency output interface.
The invention has the beneficial effects as follows: exclusively enjoy 10Mbps bandwidth EOC and can be every user and provide 10Mbps to exclusively enjoy bandwidth, help the broadcasting and TV operation and carry out IPTV, new value-added services such as VOD program request.And can be that every user disposes and change concrete bandwidth in development, in operation, have very big flexibility according to practical business.Make full use of existing CHINA RFTCOM Co Ltd, save the line construction cost.Solve in the building and lay category-5 cable constructional difficulties problem again.Make the WIFI signal be sent to each terminal space simultaneously.This local side apparatus is installed simple, disposes fast, need not rewiring, need not to disturb residents.
