Wire network access system and wire network access method with tunable working frequencies

Abstract

The invention provides a wire network access system and a wire network access method with tunable working frequencies. The system comprises user-end two-way communication equipment, and local-side two-way communication equipment, wherein the user-end equipment is connected with a wire network through an internal or external radiofrequency device; the local-side equipment is connected with the wire network through an internal or external radiofrequency device; and the working frequencies realized by the radiofrequency devices can be tuned at any time. The wire network access system and the wire network access method with the tunable working frequencies can ensure that the user-end equipment is switched to different working frequencies at any time and performs two-way communication with the local-side equipment in the corresponding working frequencies, and can also freely determine the working frequencies of the local-side equipment according to the need, so compared with the prior wire network access system of fixed working frequencies, the system has better flexibility, can arrange more communication service, can provide better communication service, and can more fully utilize frequency spectrum resources.

Description

technical field [0001] The invention relates to a wired network access system and method with tunable working frequency. Background technique [0002] In wired network transmission, data transmission devices are usually installed at both ends of the wired network, and communicate according to a preset frequency. In order to save network resources, the existing wired network usually transmits multiple signals on the same line, and the working frequency of each signal is different. In this way, different signals can be transmitted in the same wired network to save network resources. However, in this method of the prior art, the frequencies of the data transmission device at the central office and the data transmission device at the user end are preset, so that a specific terminal receives data sent by a specific central office device. In this way, although a wired network can be used to transmit a variety of different signals, the data transmission devices at the central off...

Problems solved by technology

In this way, although a wired network can be used to transmit a variety of different signals, the data transmission devices at the central office and the terminal are frequency-locked, resulting in poor flexibility and scalability of the network.
