Abstract

The invention discloses a coaxial access network unit device with WIFI (wireless fidelity). The coaxial access network unit device comprises an RJ(registered jack)-45 data interface group, an Ethernet exchange chip, an EOCMAC (ethernet over coax media access control) chip, an EOC (Ethernet over coax) physical layer chip, a network transformer, a duplex filter, a data coaxial F interface, a wired television coaxial F interface, a radio frequency chip and antennae, wherein a low-frequency output port of the duplex filter is connected with the data coaxial F interface, and is connected with the network transformer and the EOC physical layer chip in sequence and then is connected with the EOCMAC chip by an MII (media independent interface) data interface; and the high-frequency output port of the duplex filter is connected with the wired television coaxial F interface. With the adoption of the coaxial access network unit device, the current wired television network is sufficiently used, high-speed data access of a wired television user can be conveniently and economically achieved, thereby the requirements that the multi-data terminal device of the user is simultaneously accessed by adopting a wireless manner and a wired manner.

Description

technical field [0001] The invention relates to a coaxial access network unit device equipped with wireless WIFI, which is suitable for simultaneously receiving cable TV signals and transmitting and receiving broadband data signals; the device belongs to the technical field of coaxial broadband multi-service access networks. Background technique [0002] At present, the application of communication systems has been developed by leaps and bounds. Digital technology and network technology have been popularized and applied. The demand for input is increasingly strong, and the trend of "triple play" is becoming more and more obvious. [0003] According to data, the investment in subscriber lines accounts for 40%-50% of the investment in the entire access network. If the existing network can be used to realize broadband network access, then the laying of expensive new communication networks can be avoided. Cable television network (CATV), as one of the networks with the widest c...
