Introduction

Annotation

Modern tendencies of telecommunication development necessitate operators to search for the most optimal technologies, allowing you to satisfy drastically growing needs of subscribers, maintaining at the same time consistency of business processes, development flexibility and reduction of costs of various services provision. Wireless technologies are spinning up more and more and have paced a huge way for short time from unstable low-speed communication networks of low radius to broadband networks equitable to speed of wired networks with high criteria to the quality of provided services.

WOP-2ac device is a Wi-Fi access point of Enterprise class. The device enclosed into hermetic case which allows to use the access point outdoor in different climatic conditions – at temperatures from –40 to +65 °С. This manual specifies intended purpose, main technical parameters, design, installation procedure, safe operation rules and installation recommendations for WOP-2ac.

Delivery package

The delivery package includes:

• WOP-2ac wireless access point;
• Mounting kit;
• 1 connectors for RJ-45;
• Operating manual (supplied on a CD);
• Conformity certificate;
• Technical passport. 

Installation order

This section defines safety rules, installation recommendations, setup procedure and the device starting procedure.

Safety rules

1. Do not open the device case.. There are no user serviceable parts inside.
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 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.
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.

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.
