Problems solved by technology
[0003] However, the existing wireless bridges have the following problems: the access mode is POE (power on ethernet, Ethernet transmission power supply) electrical port, the access mode is single, and the power supply mode is single, which cannot be applied to many different scenarios; only the electrical port is supported For transmission, it is necessary to lay out network cables and make crystal heads. The process is cumbersome and is easily affected by the production process of crystal heads; network cables are mainly deployed indoors, and are not suitable for long-term exposure to the wind and sun, leaving hidden dangers to the stability and safety of signal sources in the later stage ; Fixed with cable ties, the up and down inclination cannot be changed after installation and it is easy to fall off, which increases the difficulty of commissioning and installation environment

Embodiment Construction
[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0038] The wireless bridge is mainly set up between the two networks to realize the interaction of signals. Taking the mobile communication network as an example, the PTN (Packet Transport Network, Packet Transport Network) transmission and the base station are connected to the wireless bridge through a network cable or optical cable, and the two wireless bridges perform data interaction through radio waves, and finally realize the PTN transmission and the base...

Description
technical field [0001] The invention relates to the technical field of wireless network bridges, in particular to a wireless network bridge. Background technique [0002] The existing mobile base station / camera monitoring will use wireless transmission equipment such as wireless bridges and microwaves when transmitting data back. When the base station / camera is connected to the wireless bridge, the network cable is used for data interaction. [0003] However, the existing wireless bridges have the following problems: the access mode is POE (power on ethernet, Ethernet transmission power supply) electrical port, the access mode is single, and the power supply mode is single, which cannot be applied to many different scenarios; only the electrical port is supported For transmission, it is necessary to lay out network cables and make crystal plugs. The process is cumbersome and is easily affected by the production process of crystal plugs; network cables are mainly deployed in...
