Introduction

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 a short time from unstable low-speed communication networks of low radius to broadband networks equitable to speed of wired networks with high criteria for 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 on a large area.
This manual specifies intended purpose, main technical parameters, design, installation procedure, safe operation rules and installation recommendations for WEP-2ac and WEP-2ac Smart wireless access points.

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 devices are 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 high requirement to the quality and allows transmitting more important traffic in more priority queue. Prioritization is provided due to QoS main technologies: CoS (tags in VLAN packet fields) and ToS (tags in IP packets). Besides the standard methods of prioritization, the 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 (supplied on a CD);

Installation rules

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

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.

   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. 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:
   1. Install the device at the center of the wireless network;
   2. Minimize the number of obstacles (walls, roof, furniture, etc.) between WEP-2ac/WEP-2ac Smart 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 at 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. 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. Decreasing of the signal level on cells borders to -75 dBm is permitted if it does not involve the use of VoIP, streaming video and other traffic that is sensitive to losses in a wireless network.

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.

Channel selection for neighboring access points

• It is recommended to set non-overlapping channels to avoid interchannel interference between neighboring access points.

• The example of channel allocation scheme among neighboring access points in the frequency range of 2.4 GHz when channel width is 20 МHz:

Scheme of channel allocation among neighboring access points in the frequency range of 2.4 GHz when channel width is 20 MHz

• It is recommended to save the same allocation scheme between floors, see the figure below: 

Scheme of channel allocation between neighboring access points that are located on different floors

• When the width of used channel is 40 MHz, there is no non-overlapping channels in the frequency range of 2.4 GHz. In such cases, you should select channels maximally separated from each other:

Channels used in a range of 5GHz when channel width is 20, 40 or 80 MHz
