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. WEP-2ac and WEP-2ac Smart are Wi-Fi access points of the Enterprise class. The devices are dedicated to be installed inside buildings as access points and to create a seamless wireless network using several identical access points (roaming) on a large area.
This manual specifies intended purpose, main technical parameters, design, installation procedure, safe operation rules and installation recommendations for these devices.

Device description

Purpose

WEP-2ac and WEP-2ac Smart wireless access points (hereinafter the devices) are designed to provide users with access to a high-speed and safe network.

The device is dedicated to create L2 wireless networks interfacing with a wired network. WEP-2ac and WEP-2ac Smart are 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 devices have two radio interfaces to organize two physical wireless networks.

WEP-2ac and WEP-2ac Smart support 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). Besides the standard methods of prioritization, devices allow you to assign demands for traffic transmission almost in every packet field from MAC to TCP/UDP port. The ACL rules and shaping allow you to control access, quality of service and restrictions for all subscribers as well as for each subscriber individually.
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.

Delivery package

The delivery package includes:

  • Wireless access point WEP-2ac/WEP-2ac Smart;
  • Mounting kit;
  • User manual on a CD (optionally);
  • 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 install the device close to heat sources or in rooms with temperature below 5 °C or above 40 °C.
  2. Do not use the device in places with high humidity. Do not expose the device to smoke, dust, water, mechanical vibrations or shocks.
  3. Do not open the device case. There are no user serviceable parts inside.

Do not cover ventilation holes and do not put other objects on the device in order to prevent overheating of device components.

Installation recommendations

  1. The recommended mounting position: horizontal, on a ceiling.
  2. Before installing and enabling the device, check it for visible mechanical defects. If defects are observed, 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, follow these rules to ensure the best Wi-Fi coverage:
    1. Install the device at the center of a wireless network;
    2. Minimize the number of obstacles (walls, roof, furniture and etc.) between access point 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. It is not recommended to place the device inside a false ceiling as metal frame causes multipath signal propagation and signal attenuation.
  5. During the installation of several access points, cell action radius must overlap with action radius of a neighbouring 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.

Calculating the number of required access points

To calculate the required number of access points, 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: 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.

MaterialChange of signal level, dB
2.4 GHz5 GHz
Organic glass-0.3-0.9
Brick-4.5-14.6
Glass-0.5-1.7
Plaster slab-0.5-0.8
Wood laminated plastic-1.6-1.9
Plywood-1.9-1.8
Plaster with wire cloth-14.8-13.2
Breeze block-7-11
Metal lattice (mesh 13*6 mm, metal 2mm)-21-13

Channel selection for neighbouring access points

It is recommended to set nonoverlapping channels to avoid interchannel interference among neighbouring 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 neighbouring access points in frequency range of 2.4 GHz when channel width is 20 МHz, see Figure 4.


Figure 4 – Diagram of channel allocation among neighbouring 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 – Diagram of channel allocation between neighbouring 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.

For WEP-2ac Smart in the 5 GHz band, the Smart Antenna uses the beam switching method — this is more than 700 radiation patterns that dynamically change during the operation of the access point. WEP-2ac Smart constantly evaluates the location of customers and sources of radio interference, and then selects the optimal radiation pattern for each moment in time from 700 templates.
