2. It is required to cover unused antenna connectors by safety cover included in the device delivery package.
3. Do not install the device during a thunderstorm. There is a risk of being struck by lightning.
4. You must follow requirements for voltage, current and frequency specified in the user manual.
5. Measuring devices and computer must be grounded before connecting to the device. Potential difference between cases of equipment and measurement devices must be no more than 1 V.
6. Check the cable integrity and security of mounting to the connectors.
7. Do not install the device near heat source and at places where temperature may reach values below -40°С or higher 60°С.
8. You should satisfy established standards and requirements for working at height during the device installation on the high-rise constructions.
9. The device exploitation should be performed by specially prepared engineering and technical personnel.
10. Connect only to operational service equipment.

Installation recommendations

1. The recommended installation: attaching to a mast/pole or wall;
2. Before you install and enable device, check the device for visible mechanical defects. If defects are observed, you should stop the device installation, draw up corresponding act and contact the supplier.
3. During the device installation to provide Wi-Fi coverage area with the best characteristics take into account the following rules:
   1. Install the device at the center of a wireless network;
   2. Minimize the number of obstacles (walls, roof, furniture and etc.) between WOP-2ac and other wireless network devices;
   3. Do not install the device near (about 2 m) electrical and radio devices;
   4. It is not recommended to use radiophone and other equipment operating on the frequency of 2.4 GHz, 5 GHz in Wi-Fi effective radius;
   5. Obstacles in the form of glass/metal constructions, brick/concrete walls, water cans and mirrors can significantly reduce Wi-Fi action radius.

During the installation of several access points, cell action radius must overlap with action radius of a neighboring cell at level of -65 ÷ -70 dBm. Decreasing of the signal level on cells borders to -75 dBm is permitted if it involves the use of VoIP, streaming video and other traffic that is sensitive to losses in wireless network.

Channel selection for neighboring access points

It is recommended to set nonoverlapping channels to avoid interchannel interference among neighboring access points.

 
Figure 3 – General diagram of frequency channel closure in the range of 2.4 GHz

Example of channel allocation scheme among neighboring access points in frequency range of 2.4 GHz when channel width is 20 МHz, see Figure 4.

Figure 4 – Scheme of channel allocation among neighboring access points in the frequency range of 2.4 GHz when channel width is 20 MHz

Similarly, the procedure of channel allocation is recommended to save for access point allocation between floors, see Figure 5.

Figure 5 – Scheme of channel allocation between neighboring access points that are located between floors

When width of used channel is 40 MHz there is no non-overlapping channels in frequency range of 2.4 GHz. In such cases, you should select channels maximally separated from each other.

Network cable connection

For corrosion protection the device includes a counterpart of the hermetic RJ-45 connector.

Step-by-step installation:

1. Insert the cable into the housing through the outer retaining nut as shown in figures 18 and 19. Tighten the outer retaining nut to secure the case to the cable.

2. Perform crimping of the cable using a standard RJ45 connector.

When connecting, use the circuit diagram shown in the figure below.

3. After crimping, loosen the outer retaining nut and insert the connector all the way into the slot of the connector counterpart. The «tongue» of the connector should be pressed against it. Tighten the outer retaining nut to secure and seal the connector.

4. Insert the counterpart in the socket and tighten the mounting nut well. It depends on the reliability of the contact and tightness of the connector.

Antenna connector sealing procedure

1. Before connecting the cable to the connector, inspect the cable braid for damage and check for an O-ring in the nut of the connector, the location is shown in Figure 25 (a, b).

2. Connect the cable to the connector of the device (antenna) and tighten the nut, as shown in Figure 26 (a, b).

3. Cut the rubber sealing tape to the appropriate length: 0.15 m of waterproofing tape is required to seal one SMA connector (Figure 26a), 0.3 m of waterproofing tape is required for an N-type connector (Figure 26b), as shown in Figure 27 (a,b).

4. Remove the protective layer from the rubber band as shown in Figure 28.

Figure 28

5. Start wrapping from the cable side, with a 10-15 mm step away from the crimped part. Fix the end of the tape on the cable braid at an angle of 15...25 degrees to the cable axis, and, stretching the tape slightly, start wrapping the cable and the connector, advancing towards the device body. Lay the coils overlapping each other, no folds are allowed on the coils. The cable wrapping is shown in Figure 29 (a, b).

6. Having reached the housing of the device (antenna) by the edge of the tape, it is required to make a turn around the connector, pressing as much as possible the edge of the tape to the housing, then continue winding the tape at a different angle, moving away from the housing. When winding, do not forget to stretch the tape and press it tightly to the previously wound coils. At the tip of the ribbon, reduce the stretch and press it tightly against the coils on the cable braid, as shown in Figure 30 (a, b).

7. Cut PVC tape (duct tape) to the appropriate length: 0.28 m of duct tape is required to seal one SMA connector, 0.6 m of duct tape is required for an N-type connector. Tape is required to protect the rubber band from UV rays. The duct tape is shown in Figure 31.

Figure 31

8. Start wrapping from the cable braid, having preliminarily stepped back from the first coil of the rubber tape by 5-10 mm. Fix the end of the tape on the cable at an angle of 15...25 degrees to the cable axis, and, slightly stretching the tape, start wrapping the cable and the connector, advancing towards the device body. Lay the coils overlapping each other, no folds are allowed on the coils. The winding of the cable is shown in Figure 32.

Figure 32

9. Having reached the housing by the edge of the tape, it is required to make a turn around the connector, pressing the edge of the tape to the housing as much as possible, then continue winding the tape at a different angle, moving away from the housing. When winding the tape tightly, do not allow any folds. On the last turns of the tape, reduce the stretch to zero and lay the last turn without stretching, as shown in Figure 33 (a, b).

10. Check the sealed connector for visible areas of rubber tape.
