Embodiment 1

[0035] see figure 1, the gigabit broadband access system of wireless and wired integration, the central controller ICWS (1) is sequentially connected to the optical fiber distribution network ODN (2), the wired and wireless access station CWAP (3), the coaxial distribution network CDN (4) and Wired and wireless network unit CWNU (5) constitutes. The central controller ICWS is responsible for ICW system management, including CWAP management, user equipment CWNU management, network management and system configuration management. The Wired Wireless Access Point CWAP provides reliable, secure and high-performance all-wireless connectivity for cable television network operators. The network terminal CWNU is a distributed active antenna terminal, which realizes broadband access for users and full wireless gigabit coverage in the home.

Embodiment 2

[0037] This embodiment is basically the same as Embodiment 1, and the special features are as follows:

[0038] The central controller ICWS (1) is located at the front end of the network and is responsible for the control and management of the entire network, including support for user service authentication, authentication, billing, network service planning, and network security implementation.

[0039] The wired and wireless access station CWAP is located at the optical node of the cell, and generates a signal from the Ethernet data signal according to the 802.11n / ac protocol, and transmits it through the antenna to realize the wireless coverage of the user's outdoor cell.

[0040] The signal generated by the wired and wireless access station CWAP according to the 802.11n / ac protocol is mixed with the radio and television signal through down-frequency technology, sent to the coaxial antenna distribution network, and delivered to each room of the user by the coaxial distributi...

Embodiment 3

[0044] This embodiment is basically the same as Embodiment 1, and the special features are as follows:

[0045] see figure 2 , a schematic diagram of the wired and wireless converged broadband access network system combined with EPON network. Downlink direction: ICWS (1) sends user data signals, broadcast TV signals, and network management OAM signals generated by them to the front-end equipment OLT (9) of the EPON network (8), and the passive optical distribution network PODN (10) Delivered to each cell node ONU (11). The ONU demodulates the user's Ethernet data and broadcast TV signals and sends them to the CWAP (3). CWAP converts the data signal according to the 802.11n / ac protocol to realize the conversion of the data signal. After the conversion, the signal is divided into two channels, one is sent by the antenna (6) to achieve wireless signal coverage within the cell area; the other is sent to the coaxial antenna distribution network (4) through the frequency reducti...

Abstract

The invention relates to a wireless-cable hybrid gigabit broadband access system. The wireless-cable hybrid gigabit broadband access system is constructed through sequential connection of a central controller ICWS with an optical distribution network (ODN), a cable-wireless access point (CWAP), a coaxial distribution network (CDN) and a cable-wireless network unit (CWNU), wherein a central controller CWTS is responsible for management of the wireless-cable hybrid gigabit broadband access system, including management of the CWAP, user management, network management and system configuration management; the CWAP provides reliable, safe and high-performance all-wireless communications for a cable television network operator; and the CWNU is combined with a coaxial home network to provide a distributed active antenna terminal in order to realize broadband access of a user and all-wireless gigabit coverage in a home. Through adoption of the wireless-cable hybrid gigabit broadband access system, user indoor-outdoor broadband wireless access based on an existing hybrid fiber coax can be realized.

Description

technical field [0001] The invention belongs to the technical field of broadband access, and in particular relates to a wireless and wired gigabit broadband access system. The present invention combines the coaxial home distribution network and wireless WiFi technology, utilizes the coaxial distribution network to realize the distributed antenna function and the propagation and distribution function of TV signals and data signals, realizes the unification of wired access and wireless access, and the wireless indoor and outdoor coverage Unite. Background technique [0002] With the penetration of Internet services, broadband wireless mobile access has become the development direction of the next generation network in order to meet the needs of fast access anytime and anywhere. However, traditional wired broadband technologies, such as EPON, EOC and other technologies, although they can realize broadband access for users, do not have the capability of wireless access. The tr...
