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-12ac device is a Wi-Fi access point of Enterprise class. The device is dedicated to be installed inside buildings as an access point and to create a seamless wireless network using several identical access points on a large area.

Device description

Purpose

WEP-12ac wireless access point (hereinafter the device) 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-12ac 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-12ac 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). Besides the standard methods of prioritization, the device allows 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.  

WEP-12ac is 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:

• WEP-12ac wireless access point;
• Mounting kit;
• Operating manual (supplied on a CD);
• Conformity certificate;
• Technical passport.

Installation order

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

Safety rules

• Do not install the device near heat source and at places where temperature may reach values below 5°С or higher 40°С.
• 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.
• Do not cover ventilation holes and do not put other objects on the device in order to prevent overheating of device components.

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:

1. Install the device at the center of a wireless network;
2. Minimize the number of obstacles (walls, roof, furniture and etc.) between WEP-2ac 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.

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.

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-12ac 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 case of no obstacles, the radius of the coverage area is up to 2.4 GHz — up to 100 m, 5 GHz — up to 60 m.The table below describes rough attenuation values. 

Table 4 – Attenuation values

It is recommended to set nonoverlapping channels to avoid interchannel interference among neighboring access points.

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 МHz, see figure below.

Scheme of channel allocation among neighboring 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 below.

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.

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