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 theese devices.
Notes contain important information, tips or recommendations on device operation and setup. |
Notes and warnings
Warnings are used to inform the user about harmful situations for the device and the user alike, which could cause malfunction or data loss. |
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, 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, 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.

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

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 МHz, see Figure 4.
Figure 4 – 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 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.

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.

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. |
