Radio and Television New Media Coaxial Cable Connected to the Internet under the Internet of Things

As more and more data is uploaded or downloaded, the Internet becomes more and more important as a medium for data to the cloud. People's demand for network and network speed is becoming more and more intense. However, the convenience of accessing the Internet can not develop rapidly with cloud computing. For some areas where network cables are not laid or old network cables need to be upgraded, large-scale laying or updating of cables will cost a lot of manpower and material resources. So, can you use the existing equipment to achieve network access?
This problem is also a direction that the radio and television Internet of Things industry has been studying. In the forum of 2014 China International Internet of things Expo held last week, Zhang Xuebin of Hubei herdsman Network Technology Co., Ltd. discussed how to realize home broadband access by using existing cable TV coaxial cable in a speech on the theme of "radio and television broadband-FTTx access and home Internet of things.
Zhang Xuebin said that since the cable TV industry began to develop two-way HFC network technology in 1995, the optical fiber network has continued to extend and the cable network has continued to retreat. From the "last 1 kilometer", "last 500 meters", "last 100 meters" to the "last 10 meters" after FTTH, coaxial cable is still the characteristic and advantage of cable TV network.
With the existing cable TV fiber broadband access, the use of coaxial cable to overcome the problem of broadband into the home, into the room. "Wrangler continues to explore the communication resources and value of coaxial cable, and through independent research and development of high-frequency, broadband, multi-channel frequency division multiplexing technology, make full use of the coaxial cable widely existing in homes, hotels and other buildings and traditional video monitoring systems, to solve the" last 100 meters "broadband access, radio frequency (RF) TV signal transmission and equipment power supply and other issues, it can realize common cable transmission (super G access) of signals and power supplies such as 10/100BASE-T, CATV, 3G/WiFi/ZigBee, etc,".
Cable TV network is one of the largest access networks in China, which is the market advantage of carrying out services. Cable TV coaxial cable network not only into thousands of households, but also extends to the user's family of multiple living rooms. In other words, the "room entry rate" of CATV coaxial cable network is beyond the reach of other communication networks. If the "in-room" resources of the cable TV coaxial cable network can be used, the network tentacles of interactive TV services will be all over the effective living space of the user's home, and the access point will be everywhere, closely following the broadcast TV signal outlet.
"The widespread existence of coaxial cables is the material basis and advantageous resources of radio and television networks. Coaxial cable has many advantages such as attenuation characteristics, service life, tensile resistance, extrusion resistance and other engineering performance and cost price, "Zhang Xuebin stressed," these advantages are irreplaceable in at least 10 years ".
At present, FTTB (fiber to building head) has become the mainstream of radio and television optical network, FTTH (fiber to the home) is the development trend; "1 household, 1 line, passive centralized distribution" has become the mainstream structure of the last 100 meters cable network. The Wrangler solution covers a wide range, including broadband, narrowband, wired and wireless access networks based on coaxial cable, such as radio and television, telecommunications, interconnection, and Internet of Things. Practice has proved that the radio and television broadband network on this basis to achieve 100M broadband home has a great advantage.
