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. Do not install the device near (about 2 m) electrical and radio devices;
   3. It is not advised to use radio-phones and other devices, working on frequency of 5 GHz, within a range of Wi-Fi wireless network;
   4. Obstacles in the form of glass/metal constructions, brick/concrete walls, water cans and mirrors can significantly reduce Wi-Fi action radius.
4. 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.

Frequency bands and channels in the range of 5 GHz for Wi-Fi

Data transmission in the 5 GHz band is used for IEEE 802.11a/n/ac standards. The number of channels used varies by country. Figure 3 shows the distribution of frequency channels in the 5 GHz band with a width of 20 MHz, 40 MHz, 80 MHz.
To calculate the Wi-Fi channel central frequency f, MHz, use the equation:

f = 5000 + (5*N),

where N – Wi-Fi channel number.

Figure 3 – Channels allocation in range of 5 GHz when channel width is 20, 40 or 80 MHz

When using the WOP-12ac-LR device, the following rules should be considered:

1. When working with one radio interface, any of the available channels is selected.
2. When working with two radio interfaces: Radio1 – channels from 36 to 64; Radio2 – channels from 100 to 144 or from 149 to 165.
3. When working with three radio interfaces: Radio1 – channels from 36 to 64; Radio2 – channels from 100 to 144; Radio3 – channels from 149 to 165.

Network cable connection

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

Figure 11 – Hermetic RJ-45 connector on the device and counterpart in disassembled form

Figure 12 – Counterpart of hermetic metal connector

Step-by-step installation:

1. Insert the cable into the housing through the outer retaining nut as shown in figure 13. Tighten the outer retaining nut to secure the case to the cable.

Figure 13 – Fastening the counterpart 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.

Figure 15 – View of the counterpart attached to the cable

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.

Figure 16 – View of the connected cable to the device network interface

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 17 (a, b).

2. Connect the cable to the connector of the device (antenna) and tighten the nut, as shown in Figure 18 (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 18a), 0.3 m of waterproofing tape is required for an N-type connector (Figure 18b), as shown in Figure 19 (a,b).

4. Remove the protective layer from the rubber band as shown in Figure 20.

Figure 20

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 21 (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 22 (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 23.

Figure 23

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 24.

Figure 24

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 25 (a, b).

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