Embodiment Construction

[0010] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0011] Such as figure 1 As shown, the home gateway mainly adopts the ADSL+WiFi integration method. The system includes: external power supply, memory, CPU central processing unit, wired LAN processing circuit, wireless LAN processing circuit, ADSL2+ processing circuit, ATM processing circuit, USB Interface circuit and indicator circuit. The main functions and specific implementation steps of the home gateway: First, the ADSL signal is processed and disassembled according to the ATM data (asynchronous transmission mode) through the ATM processing circuit; second, the ADSL signal after the ATM processing circuit is modulated and demodulated. Enter the ADSL2+ processing circuit, modulate and demodulate the data on the copper wire, and convert it into a digital signal; third, send the signal processed by the ADSL2+ processing circuit to the CPU central processing un...

Abstract

The invention relates to an intelligent home gateway, which comprises a central processing unit CPU, a storage unit, a cable local area network processing circuit, a wireless local area network processing circuit and the like, wherein the storage unit, the cable local area network processing circuit, the wireless local area network processing circuit and the like are connected with the CPU. The home gateway also comprises an ATM processing circuit and an ADSL2+ processing circuit, wherein the ATM processing circuit analyzes data from a copper wire and decomposes the data in an asynchronous transmission mode; and the ADSL2+ signal processing circuit demodulates the data, transmitted by the copper wire, of Internet, converts the data into a digital signal and transmits the digital signal to the CPU for the CPU to uniformly regulate and control the digital signal, and finally the digital signal is converted by the wireless local network processing circuit into a Wi-Fi wireless broadband signal to be broadcast or is processed by the cable local area circuit and transmitted to terminal equipment connected with the interface of the cable local area circuit. The home gateway integrates the functions of an ADSL asymmetric digital subscriber line and Wi-Fi, provides users with an intelligent and flexible home network interface unit, and better serves the users by effectively using the increasingly developed network.

Description

Technical field [0001] The invention relates to an intelligent home gateway, in particular to a home gateway that integrates asymmetric digital subscriber line ADSL and wireless broadband WiFi. Background technique [0002] The home gateway is an access device that connects the networked information equipment in the home and the broadband access network. It is a simple, intelligent, standardized, and flexible entire home network interface unit, which can vary from The external network receives the communication signal, and then transmits the signal to a certain smart device in the home through the home network, and uses an increasingly developed network to enable users to manage and control the internal devices of the home through external devices. In the past, home gateways generally only had a single asymmetric digital subscriber line ADSL function or a single wireless access device AP function, and their use range was limited and their applications were not flexible enough. S...
