Wireless Bridge Networking Principles in Outdoor Environment
First, for outdoor point-to-point transmission, the primary consideration is whether or not the sight distance is propagated. If there is no condition for sight distance propagation, outdoor wireless bridge equipment cannot be used. A certain range of blocking can be solved by increasing the antenna.
Second, the problem to be considered is the distance between two points, which determines the loss of the signal through the space propagation, so as to select the device transmit power, antenna gain, whether to use the amplifier, whether to need relay transmission to provide a reference.
Third, the issue to be considered is the user's bandwidth requirements.
Fourth, the issue that needs to be considered is the wireless electromagnetic environment where the project is located, that is, the presence or absence of similar signal sources needs to be detected to prevent interference between electromagnetic signals.
Fifth, the problem that needs to be considered is the climate environment where the equipment is located, such as the range of temperature changes, which provides the basis for equipment selection.
For the point-to-multipoint situation, the difference between the received signal strengths of the edge nodes needs to be considered to avoid uneven bandwidth allocation.
It is also necessary to consider the type of device interface that the user can provide (whether protocol conversion is required).
To sum up the above solutions, it is necessary to emphasize that the wireless LAN device in the public area must have the client isolation function. For companies and internal wireless LAN devices, this feature is often not required. In addition, wireless LAN devices in public areas need to support multiple authentication functions, and companies and internal wireless LAN devices do not need this function. Therefore, in the design of the program and the selection of equipment, it must be targeted, as far as possible according to local conditions.

Tape measure is a commonly used tool in daily life, and it is one of the necessary tools for the family. Luban ruler, Feng Shui ruler, and Wen Gong ruler are also Steel tape measures. Steel tape measure is a common tool for construction and decoration.
Steel tapes can be divided into self-rolling tapes, braking tapes, and rolling tapes. Other names of steel tape measure are: steel tape measure, steel box ruler.
