Embodiment 1

[0030] In order to solve the problem that in the prior art, when wireless network coverage is performed on multiple rooms in the network area, it is necessary to replace the high-frequency branch distributor, resulting in high wireless network coverage costs, and when high-frequency signals are transmitted on coaxial cables, Due to the problems of large attenuation and short transmission distance, this embodiment provides a signal conversion device, please refer to Figure 4 :

[0031]The signal conversion device 40 can be applied to home network coverage. It should be understood that, in addition to the home, the signal conversion device is also used for wireless coverage of the networked area where he needs to use the network. In addition to the usual family, the network area also includes offices, as well as public places such as movie theaters, shopping malls, and rail trains. The signal conversion device 40 in this embodiment has a significant advantage in realizing wir...

Embodiment 2

[0049] This embodiment will continue to introduce the signal conversion device, the signal coupling device, and the wireless network coverage system in the foregoing examples. The architecture of the wireless network coverage system provided in this embodiment is similar to that in the first embodiment, but the signal conversion device and the signal coupling device are different from those in the first embodiment. So first, see Figure 7 Schematic diagram of the structure of the signal conversion device shown:

[0050]The signal conversion device 70 includes a transceiving unit 71, a converting unit 72 and a frequency mixing unit 73, wherein the transceiving unit 71 can still receive radio frequency signals, and the converting unit 72 can convert the radio frequency signals received by the transceiving unit into coaxial adaptation signals . It should be understood that in many cases, there are more than one radio frequency signals interacting between the access device and t...

Embodiment 3

[0058] This embodiment will introduce the signal conversion device, the signal coupling device, and the wireless network coverage system in the foregoing embodiments with reference to specific examples. Please refer to Figure 9 :

[0059] Figure 9 Shown is an architectural schematic diagram of a wireless network coverage system, wherein the wireless network coverage system 9 includes an access gateway 91 , a frequency synthesizer 92 , a branch distributor 93 , a coaxial cable 94 and a coupling antenna 95 . The structure of the frequency synthesizer 92 may refer to the signal conversion device in the foregoing embodiment, and the coupling antenna 94 is a device that integrates the WLAN antenna and the signal coupling device in the foregoing embodiment.

[0060] The frequency synthesizer 92 is connected to the WiFi antenna interface of the access gateway 91, which can receive the radio frequency signal from the access gateway 91, and then performs down-frequency processing on...

Abstract

Embodiments of the present invention provide a signal conversion, signal coupling device and wireless network coverage system, wherein the signal conversion device and the signal coupling device are applied between the access device and the wireless local area network antenna. Due to the processing of the signal conversion device and the signal coupling device, It not only ensures that the access device and the wireless LAN antenna can still use radio frequency signals to interact with other external devices, but also the coaxial adaptation signal via the branch distributor must meet the requirements of the branch distributor with a frequency less than or equal to 1000MHz, so there is no need for network coverage. The high-frequency branch distributor is specially replaced to avoid the problems of high cost and equipment waste caused by the replacement of equipment. On the other hand, the frequency of the converted coaxial adaptation signal must be lower than 1000MHz, so when using the coaxial cable to transmit the signal with this lower frequency, it can avoid large attenuation, increase the transmission distance, and improve the transmission distance for users. Provide a better online experience.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a signal conversion, signal coupling device and a wireless network coverage system. Background technique [0002] With the rapid development of FTTH (Fiber To The Home, fiber to the home), it is very common for the home bandwidth to exceed 100M. In theory, such a bandwidth can provide users with a better Internet experience. But in fact, the user experience also depends on the coverage of the wireless network in the network area. The current access equipment 10, or home equipment, such as ONT (Optical Network Terminal, optical network terminal) or CPE (Customer Premise Equipment, customer terminal equipment) with its own WiFi AP (Wireless-Fidelity Access Point, wireless fidelity access point) in point) devices such as figure 1 As shown, basically, wireless signals are sent and received through an external WLAN (Wireless Local Area Networks, wireless local ...
