Problems solved by technology

For example, because the electromagnetic waves emitted by the radio are horizontal or vertical plates, the electromagnetic waves will be resisted or attenuated by the vertical direction (such as the floor plate) or the horizontal (dividing wall) of the building in the building, and the normal operation of the communication cannot be guaranteed.

Embodiment 1

[0013] Such as figure 1 As shown, the electromagnetic signal WiFi transmitted by the AP is directly mixed with the cable TV signal CATV that has been amplified by radio frequency (RF) in the coaxial cable, and then distributed by the high frequency distributor of the cable TV, and then passed through the passive coaxial cable The network is fed to the transmitting antenna in the user's home, and the electromagnetic signal WiFi transmitted by the AP is received by the user's broadband wireless access device; similarly, the electromagnetic signal WiFi sent by the user's broadband wireless transmitting device is passed through the passive coaxial cable network by the receiving antenna in the user's home After mixing, it reaches the receiving circuit of the AP.

Embodiment 2

[0015] Such as figure 2 As shown, the electromagnetic signal WiFi transmitted by the AP is distributed through the distributor, and then the distributed electromagnetic signal WiFi is respectively fed into the coaxial cables distributed by the centralized distributor to be mixed with the cable TV signal CATV, and then fed to On the transmitting antenna in the user's home, the electromagnetic signal WiFi transmitted by the AP is received by the user's broadband wireless access device; otherwise, it is the same as in the first embodiment.

Embodiment 3

[0017] Such as image 3 As shown, the electromagnetic signal WiFi transmitted by the AP is directly mixed with the cable TV signal CATV that has been amplified by radio frequency (RF) in the coaxial cable after being down-converted, and then distributed by the centralized distributor of cable TV, and then passed through the passive After the coaxial cable network is up-converted to the user's home, it is fed to the transmitting antenna, and the electromagnetic signal WiFi transmitted by the AP is received by the user's broadband wireless access device; similarly, the electromagnetic signal WiFi sent by the user's broadband wireless transmitting device is received by the antenna in the user's home. After being up-converted, it is mixed by the passive coaxial cable network, and then reaches the receiving circuit of the AP through up-conversion for transmission.

Abstract

The invention relates to a method for implementing wideband wireless access by coaxial cable of wired TV, and it is composed of wireless access equipment, coaxial cable of wired TV and user wideband wireless accessing / transmitting equipment, and its character is that: the electromagnetic signal of the wireless access equipment is fed back to the coaxial cable, and the electromagnetic wave passes through the floor or partition by the coaxial cable to the user wideband wireless accessing / transmitting equipment so as to be transmitted or received; for nearer transmission, the shorter coaxial cable is used to directly feed the electromagnetic wave back without frequency change; for longer-distance transmission, after the power is converted by a high frequency meter to a lower frequency efficiency, the electromagnetic wave is fed back. The invention raises the utilization benefits of the coaxial cable network of the wired TV and simultaneously solves the problem of assuring normal communication operation for wireless wideband network access by low cost.

Description

technical field [0001] The invention belongs to an Ethernet wireless access method, in particular to a method for realizing broadband wireless access by using a cable TV coaxial cable. Background technique [0002] At present, broadband wireless access technology is developing rapidly, but due to its specific operating frequency (2G-5G), its application in buildings encounters many problems. For example, because the electromagnetic wave emitted by the radio is horizontal or vertical, the electromagnetic wave will be resisted or attenuated by the vertical direction (such as the floor plate) or the horizontal (partition wall) of the building in the building, and the normal operation of the communication cannot be guaranteed. Contents of the invention [0003] The object of the present invention is to provide a method for realizing broadband wireless access by using coaxial cables without being subject to vertical or horizontal ...
