3 Installation rules
This section defines safety rules, installation recommendations, setup procedure and the device starting
procedure.
3.1 Safety rules
1. Do not install the device near heat sources and in rooms with environment temperature below 5°С or higher
40°С.
2. Do not use the device in room with high level of humidity. Do not expose the device to smoke, dust, water,
mechanical vibrations or shocks.
3. Do not open the case of the device. There are no user serviceable parts inside.
3.2 Installation recommendations
1. Recommended location for device installation: horizontal, on a ceiling.
2. Before you install and enable the 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. If the device has been exposed for a long time at a low temperature, it must be left to stand for two hours at
room temperature before use. After a long stay of the device in conditions of high humidity, let it stand
under normal conditions for at least 12 hours before switching on.
4. During the device installation to provide Wi-Fi coverage area with the best characteristics take into account
the following rules:
a. Install the device at the center of the wireless network;
b. Minimize the number of obstacles (walls, roof, furniture, etc.) between WEP-2ac/WEP-2ac Smart and
other wireless network devices;
c. Do not install the device near (about 2 m) electrical and radio devices;
d. It is not recommended to use radiophone and other equipment operating at the frequency of 2.4 GHz,
5 GHz in Wi-Fi effective radius;
e. Obstacles in the form of glass/metal constructions, brick/concrete walls, water cans and mirrors can
significantly reduce Wi-Fi action radius. It is not recommended to place the device inside a false
ceiling as metal frame causes multipath signal propagation and signal attenuation.
5. In case of the installation of several access points, cell action radius must overlap with action radius of a
neighboring cell at level of -65 ÷ -70 dBm. Increasing this level up to -75 dBm is allowed if it does not involve
the use of VoIP, streaming video and other traffic that is sensitive to losses in a wireless network.
3.3 Calculating the required number of access points
To calculate the required number of access points, you need to evaluate the required coverage zone. For a more
accurate assessment, it is necessary to make a radio examination of the room. Approximate radius of coverage
area of WEP-2ac with a good-quality signal in case of mounting on a ceiling in typical office: 40-50 m at 2.4 GHz
and 20-30 m at 5 GHz. In case of no obstacles, the radius of the coverage area is up to 100 m at 2.4 GHz and up to
60 m at 5 GHz.
The table below describes rough attenuation values.
Do not cover ventilation holes and do not put other objects on the device in order to prevent
overheating of device components.
