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-12ac device is a Wi-Fi access point of Enterprise class. Purpose: 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.

This manual specifies intended purpose, main technical parameters, design, installation procedure, safe operation rules and installation recommendations for WEP-12ac.

Device description

Purpose

WEP-12ac wireless access point (hereinafter the device) is designed for provision of users' access to high-speed safe network.

...

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.

Device specification

Interfaces:

• 2 Ethernet ports of 10/100/1000Base-T, 1 port out them supports PoE+ technology
• Console RJ-45;

Reset to the default settings

In order to reset the device to factory settings, press and hold the 'F' button until «Power» indicator starts flashing. Device will be rebooted automatically. DHCP client will be launched by default. If the address is not received via DHCP the device will have IP address — 192.168.1.10, subnet mask — 255.255.255.0 and User Name/Password to access via Web interface: admin/password.

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 close to heat sources or in rooms with temperature below 5 °C or above 40 °C.

...

Installation recommendations

The recommended installation: Horizontal, on a ceiling.

...

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 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.

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 4.

Similarly, the procedure of channel allocation is recommended to save for access point allocation between floors, see Figure 5.

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.

Installing WEP-12ac

The device should be attached to plain surface (wall or ceiling) in accordance with the safety instruction and recommendations listed above.

The device delivery package includes required mounting kit to attach the device to plain surface.

Wall mounting

1. Fix the bracket (included in the delivery package) to the wall:

...

1.3. Align together four boltholes on bracket and boltholes on the device surface. Screw the brackets to the device surface by using screwdrive.

2. Install the device.
