Problems solved by technology
The current TV network adopts the broadcast mode, and users can only receive TV programs through the access devices such as amplifiers and splitters, and cannot perform two-way communication, and cannot carry out voice services and data services.
[0006] To sum up, the current types of telecommunications services are networked separately, and services are connected to dedicated terminals through dedicated access devices, resulting in waste of line resources. In some areas, repeated networking is carried out, and users carry out various In service, different access devices are required for different services, which increases user costs

The present invention discloses a wireless access forwarding device. The device includes a signal receiving and transmitting device, a signal conversion device and cables for connecting the two above devices. The signal receiving and transmitting device is used for receiving, processing and transmitting a radio-frequency signal carrying audio service, broadcast television service and data service. The signal conversion device is used for respectively transmitting the signal carrying the audio service, the broadcast television service and the data service received by the signal receiving and transmitting device to an audio service terminal, a broadcast television service terminal and a data service terminal, at the same time used for transmitting a baseband signal carrying the audio service, the broadcast television service and the data service transmitted by the audio service terminal, the broadcast television service terminal and the data service terminal to the signal receiving and transmitting device. The cables comprise a High-Definition Multimedia Interface (HMDI) line for transmitting the digital television service signals, a coaxial cable as a physical carrier for the broadcast television service channel, and multiple pairs of cables for transmitting the network service signal or IP telephone service.
Description
technical field [0001] The invention relates to the field of network communication, in particular to a wireless access forwarding device which realizes the three-network integration of a telecommunication network, a broadcast television network and a computer communication network by using wireless broadband network technology. Background technique [0002] With the development of communication technology, telephone technology, data network technology and cable TV technology have developed quite maturely as single service technologies. [0003] For the telephone technology that is mainly used for voice services, its network topology is shown in Figure 1. The user's telephone terminal is connected to the distribution box through a cable, and the distribution box is connected to the telecom core network through a cable. The machine receives the voice signal and carries out the voice service. At present, computers can be connected through access devices such as Asymmetric Digi...
