Installation recommendations

1. Recommended location for device installation: communications mast/pole.
2. 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.
3. Install the device vertically on communications mast or pole in the way that the LAN port is pointed down.
4. In order to provide better receiving signal level, the sectoral antenna of a base station should be in line of sight of WB-2P-LR5. You may achive the highest signal level by antenna alignment with the help of RSSI indicators.
5. The transmitting part of the device is located on the other side from brackets. This area should be directed to base station sectoral antenna.

Note, that channel bandwidth of 80 MHz will operate only according to 802.11ac standard. If the base station has 5 or 10 MHz bandwidth, you should select the same bandwidth on the user station.
• Security mode – select security mode for wireless network:
  • Off – encryption of the wireless network is off, low security.
  • WEP – WEP authentication. WEP-key should consist of hexadecimal digits and be of 10 or 26 symbols lenght or it might be a string (a-z, A-Z, 0-9, ~!@#$%^&*()_-+= symbols) with lenght of 5 or 13 symbols. The mode is hidden in the web interface.

The function is proprietary, the transmission is not carried out according to IEEE 802.11 standards, where it is supposed to use different center frequencies for data and management traffic with 40/80 MHz bandwidth. When using the WB-2P-LR5 with WOP-2ac-LR5 devices with enabled fixed center frequency, activation at the subscriber station is not required, because happens automatically at the moment of connection to the base station.
• Limit Channels – the list of frequencies on which the air is scanned to connect to the base station.

For example, if a channel 100L (5490-5530) with a 40 MHz band is set on the BS, then in the list of allowed channels should be selected all the channels in this frequency range: 98 - 106 channel inclusive. With this setting, the WB-2P-LR5 will only scan the frequency range of 5,490 - 5,530 MHz and successfully connect to the BS on the 100L/40 channel;
