First, choose the right wireless bridge:
1, according to the needs of the environment to choose the right wireless bridge, reference factors include the bridge's operating frequency band, transmission distance, antenna gain;
2. Select the appropriate networking scheme, peer-to-peer networking, relay networking, or point-to-multipoint networking. The specific solution can be consulted before the purchase of equipment, bridge manufacturers design reasonable solutions;
3. The bridge equipment must be paired with the model. Different models of Levin's products can be used in the same group of networks but may not be compatible with other brands of products.
4, depending on the installation site of the electromagnetic interference environment, long-distance transmission of outdoor wireless bridge is generally recommended to choose 5.8G wireless bridge.
Second, the choice of installation location:
1. Installation of height wireless bridges In the process of wireless transmission, obstacles such as trees, buildings, and large-scale reinforced buildings will weaken the blocking of wireless signals. In order to improve the wireless transmission performance and prevent the signal from being damaged and the signal is weak, the user should try to ensure that there are no obstructions in the transmission path of the wireless bridge and meet the visual transmission conditions at both ends.
Both ends of the visual can not be simply understood as point-to-point visually, meaning that there must be no obstacles or potential obstacles in the Fresnel zone (radio wave terminology) in which the antenna propagates. In the above figure, the ellipse area is simply understood as the Fresnel zone, ensuring that there are no obstacles in this area. The main RF energy between the antennas is transmitted in this area, so the transmitting antenna must be higher than the height of the obstacle to maintain a line-of-sight path between it and the receiving antenna to ensure that the communication link is normal. 
2. Debugging of angles and signals Because the quality of the wireless bridge signal is directly related to the bandwidth and stability of the link, further debugging of the wireless bridge signal must be performed after the installation is completed (by adjusting the directions of the antennas on both sides, pitch angle, etc. Way to achieve the purpose of adjusting the signal strength). The signal strength status can be checked according to the signal status indicator of the bridge device or software.
Third, the installation method <br> <br> specific wireless bridge mounting method apparatus can operate in accordance with the instructions for later guidance.
1, installation precautions:
1 When the pole is installed, the selected pole should not be too thin or too thick to ensure that the standard harness can be installed directly;
2 Keep the device away from metal objects/adverse factors. (eg heating, air conditioning pipes, large ceiling structures, upper structure of buildings, and main power lines);
3 The installation of the equipment should ensure the stability is not loose;
4 If the bridge device is an external antenna, the connection of the device must be ensured;
5 When connecting the network interface of the device, it is necessary to strictly follow the installation instructions for the network bridge. If the operation is not properly performed, such as water inlet of the network port, the interface may be burned or the circuit board may be short-circuited, which may result in the failure of normal use of the device.
6 The network cable should not be bent or knotted, nor should it be too close to the strong circuit cable, otherwise it will affect the transmission. The outdoor construction must select the outdoor network cable to prevent the insulation sheet from aging.
2. Bridge installation lightning protection requirements in the field:
When wireless bridges are installed in the field, if there are no tall buildings or lightning rods in the vicinity, lightning protection measures must be taken into consideration. Lightning conductors are usually used. Generally, lightning rods are not installed separately when they are installed in the urban area or surrounded by lightning rods. When installing a bridge, it is best to use a POE lightning protection module. Ryan Technology will generally recommend adding to customers, but this kind of lightning protection module is used to prevent static electricity, surges, lightning and other damage to the wireless bridge, and it cannot prevent direct lightning.
3, power supply requirements:
The power supply voltage of the PoE power supply module of the bridge is 110V~240V. If the voltage is lower or higher than this, the normal operation of the device or the PoE power supply module may be damaged. In view of unstable field power supply voltage and high voltage, it is necessary to design a set of PoE power supply solutions (such as stabilized power supply and UPS power supply) that are suitable for working voltage. When using the PoE module to supply power to the bridge through the network cable, it is recommended that the distance be less than 100 meters.
4, equipment grounding requirements:
The wireless bridge should be grounded. If the equipment is not grounded, the equipment may operate abnormally or be damaged. The grounding resistance of the equipment should be less than 4 ohms, and it must not be shared with lightning rods and strong electric lines. If the PoE power ground wire is used, it also needs to be grounded. The user can ground with a super Category 5 (or more) shielded Ethernet cable with a ground wire combined with a PoE adapter to easily and effectively prevent static electricity and lightning strikes.
