2 Device description
2.1 Purpose
WEP-2L wireless access point is designed for provision of users' access to high-speed safe network.
The device is dedicated to create L2 wireless networks interfacing with a wired network. WEP-2L is connected to a
wired network via 10/100/1000M Ethernet interface and arrange high-speed access to the Internet for devices
supporting Wi-Fi technology at 2.4 and 5 GHz.
The device has two radio interfaces to organize two physical wireless networks.
WEP-2L supports up-to-date requirements to service quality and allows transmittingmore important traffic in
higher priorities queues. Prioritization is based on main QoS technologies: CoS (special tags in VLAN packet field)
and ToS (tags in IP packet field).
ACL rule creation functionality and support for traffic shaping on each VAP allows you to fully manage access,
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
The recommended installation: Horizontal, on a 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 to provide Wi-Fi coverage area with the best characteristics take into account
the following rules:
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 radius of coverage
area of WEP-2L with a good-quality signal in case of mounting on a ceiling in typical office: 2.4 GHz 40-50 m, 5
GHz: 20-30 m. In the absence of obstacles, the coverage radius: 2.4 GHz up to 100 m; 5 GHz up to 60 m.
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.

Plaster with wirecloth -14,8 -13,2
Breezeblock -7 -11
Metal lattice (mesh 13*6 mm, metal 2 mm) -21 -13
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.

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.

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.
