2 Device description
2.1 Purpose
WEP-3ax, WEP-3ax-Z wireless access points are designed for provision of users' access to high-speed safe
network.
The devices are dedicated to create L2 wireless networks interfacing with a wired network.WEP-3ax, WEP-3ax-
Z are connected to a wired network via 100/1000/2500M Ethernet interface and arrange high-speed access to
the Internet for devices supporting Wi-Fi technology at 2.4 and 5 GHz.
The devices have two (main) radio interfaces for organizing two physical wireless networks and a third
(additional) radio interface for independent air scanning.
WEP-3ax, WEP-3ax-Z support up-to-date requirements to service quality and allow transmittingmore important
traffic in higher priorities queues. Prioritization is based on the main QoS technologies: CoS (Special tags in
the VLAN packet field) and ToS (tags in the IP packet field).
Support for traffic shaping on each VAP allows to fully manage service quality and restrictions, both for all
subscribers and for everyone in particular.
The devices are designed to be installed in offices, state buildings, conference halls, laboratories, hotels, etc.
The creation of virtual access points with different types of encryption allows clients to delimit access rights
among users and groups of users.

3 Rules and recommendations for device installation
This section defines safety rules, installation recommendations, setup procedure and the device starting
procedure.
3.1 Safety rules
Do not install the device close to heat sources or in rooms with temperature below 5°C or above 40°C.
Do not use the device in places with high humidity. Do not expose the device to smoke, dust, water,
mechanical vibrations or shocks.
Do not open the device case. There are no user serviceable parts inside.
3.2 Installation recommendations
Recommended mounting position: horizontal, on the ceiling.
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.
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.
During the device installation, follow these rules to ensure the best Wi-Fi coverage:
Install the device at the center of a wireless network;
Minimize the number of obstacles (walls, roof, furniture and etc.) between access point and other
wireless network devices;
Do not install the device near (about 2 m) electrical and radio devices;
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;
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.
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.
3.3 Calculating the number of required access points
To calculate the required number of access points, you should evaluate the required coverage zone. For a
more accurate assessment, it is necessary to make a radio examination of the room. Approximate coverage
radius of confident reception of WEP-3ax, WEP-3ax-Z access points when mounted on the ceiling in a typical
office space: 2.4 GHz: 40-50 m, 5 GHz: 20-30 m. If there are no obstacles, range: 2.4 GHz: up to 100 m; 5 GHz
up to 60 m.
Table 4 describes approximate attenuation values.
Do not cover ventilation holes and do not put other objects on the device in order to prevent
overheating of device components.

3.4 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
For the example of channel allocation scheme among neighboring access points in frequency range of 2.4
GHz when channel width is 20 MHz, seeFigure 4.

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.

The "Wi-Fi clients" submenu displays information about the status of connected Wi-Fi clients.
Click the "Refresh" button to update the information on the page.
# – number of the connected device in the list;
Hostname – network name of the device;
IP Address– IP addressof the connected device;
MAC – MAC address of the connected device;
Interface – WEP-3ax, WEP-3ax-Z interface for interaction with the connected device;
Link Capacity – parameter that reflects the effectiveness of the use of a modulation access point on the
transmission. It is calculated based on the number of packets transmitted on each modulation to the
client, and the reduction factors. The maximum value is 100% (means that all packets are transmitted to
the client at maximum modulation for the maximum nss type supported by the client). The minimum
value is 2% (in the case when the packets are transmitted to the modulation nss1mcs0 for a client with
MIMO 3x3 support). The parameter value is calculated for the last 10 s.
Link Quality – parameter that displays the status of the link to the client, calculated based on the number
of retransmit packets sent to the client. The maximum value is 100% (all transmitted packets were sent
on the first attempt), the minimum value is 0% (no packets were successfully sent to the client). The
parameter value is calculated for the last 10 s.
Link Quality Common – parameter that displays the status of the link to the client, calculated based on
the number of retransmit packets sent to the client. The maximum value is 100% (all transmitted
packets were sent on the first attempt), the minimum value is 0% (no packets were successfully sent to
the client). The parameter value is calculated for the entire client connection time.
RSSI – received signal level, dBm;
SNR – signal/noise ratio, dB;
TxRate – channel data rate of transmission, Mbps;
