Checking the radio settings

Pre-configuration in the lab

Before installing the devices to the siteson site, we recommend to configure the basic parameters in the lab and making to make sure that the link is establishing. Step-by-step instructions for a wireless link configuration are given in the "Setting up a basic PtP link" article, we . We also recommend to pass review the "InfiLINK 2x2 / InfiMAN 2x2: Initial Link Configuration and Installation" online course.

Note
titleNOTE

During the configuration of the devices configuration in a lab, take into account the following requirements:

  • Make sure that the devices are not directed at each other in order to prevent the damage of the radio modules damage. It is possible recommended to place the devices at a distance from each other, with the antennas directed to the floor.
  • A The minimum transmit output power must be set on the devices.
  • In case of using two R5000-Omx or R5000-Lmn devices, it is recommended to connect them in the link directly , with using RF cables and RF attenuators with an attenuation of at least 40 dB for each polarization (the installation\deinstallation of the RF attenuators and of the RF cables should only be performed when the devices are switched off).
  • Failure The failure or damage of the device's radio module in case of disregarding these requirements violation void a is not covered by warranty.

Checking the radio parameters

If the wireless link is not establishing in lab conditions: , make sure that the radio parameters are set to the values determined at during the planning stage, the . The correct devices configuration of the device can be obtained using the Configuration Generator tool found on the IW Academy website. To establish a wireless link, one device must be configured as the Master, the second (or all subscribers of the base station in the point-to-multipoint topology) - as the Slave. The following parameters must be identical on both devices:

To check the wireless link parameters go to the "Basic settings" - Link settings" section. Make sure that the "Enable Link" checkbox is on.

Если на устройстве отсутствует интерфейс радио, это может быть связано с нахождением в режиме восстановления при сбросе устройства при помощи ERConsole. Завершите процесс восстановления, вернув устройство к заводским настройкам во вкладке "Обслуживание".

Проверка версии ПО

Web-интерфейс

В разделе "Обслуживание" убедитесь, что на обоих устройствах установлена одинаковая версия ПО: MINT или TDMA. Инструкция по переходу между версиями ПО MINT и TDMA доступна в статье "Переход с версии MINT на TDMA". Рекомендуем обновить устройства до последней бета-версии ПОIf the device does not have a radio interface, the reason for such behavior can be the recovery mode present during the reset of the device using the ERConsole. Complete the recovery process by returning the device to the factory settings from the Maintenance section.

Pay attention to the red values of the parameters in the interface statistics "Mode" column:

  • Operating frequency - red value of this parameter indicates an absence of data transmission due to the spectrum scanning by the DFS tool;
  • TX Power - red value for this parameter may indicate a problem with the transceiver's hardware.

Checking the firmware version

Web interface

In the "Maintenance" section, make sure that the same software version is installed on both devices: MINT or TDMA. Instructions for switching between the MINT and TDMA software versions are available in the article "How to upgrade your network from MINT to TDMA". We recommend to update the devices to the latest beta software version.

Проверка соответствия требованиям размещения устройств

Проверка сетевой инфраструктуры

Если канал связи не устанавливается после монтажа на площадке, убедитесь, что устройства не были повреждены в процессе транспортировки, проверьте целостность сетевой инфраструктуры, кабелей и источников питания.

Command line interface

To upload the software via the command line, use the "flashnet" command described in the "General Purpose Command Set" article.

Checking the installation requirements

Checking the network infrastructure

If the link is not established after the installation on site, make sure that the devices were not damaged during shipping, check the integrity of the network infrastructure, the cables and the power supplies.

Checking the installation requirements

Check if the suspension height, azimuth and elevation of the antenna match with the values obtained from InfiPLANNER. Make sure that the obstacles on the path profile are not higher than those specified during the planning phase.

Поиск помех

Web-интерфейс

Используя встроенный инструмент "Спектроанализатор" просканируйте эфир с обеих сторон канала связи, чтобы убедиться в отсутствии помехи, способной препятствовать установке беспроводного соединения, на рабочей частоте устройств и на смежных частотах. Текущая модуляция (скорость передачи данных) будет выбрана устройством в зависимости от соотношения принимаемого сигнала от удалённого устройства к шуму и помехе (CINR). Для работы на высших модуляциях параметр CINR должен быть больше или равен 28 дБ. Получить точную информацию о интересующей частоте можно наведя на неё курсором мыши. В всплывающем окне снизу доступна информация о частоте, уровне шума (в дБм), максимальном зафиксированном уровне сигнала (Max RSSI), среднем уровне сигнала (Сред. RSSI). Показатель "High RSSI" позволяет оценить количество источников сигнала, если значение существенно отличается от показателя среднего RSSI, то источников помех несколько. Показатели отображают уровень сигнала в дБ, в скобочках указан сигнал в дБм.

Interference detection

Web interface

Using the built-in Spectrum Analyzer tool, scan the air on both sides of the link to make sure there is no interference that could corrupt the signal on the device's operating frequency and on the adjacent frequencies. The current modulation (bit rate) will be selected by the device depending on the carrier to interference and noise ratio (CINR). To operate at higher modulations, the CINR parameter must be greater or equal to 28 dB. To get accurate information about the frequency, hover the mouse cursor over it. The pop-up window below provides information about frequency, noise level (in dBm), maximum signal level (Max RSSI), average signal level (Average RSSI). The "High RSSI" indicator allows to estimate the number of signal sources. If the value differs significantly from the average RSSI, then there are several interference sources. The indicators show the signal level in dB, while the signal in dBm is indicated in parentheses.

Note
titleNOTE

It is recommended to run the spectrum scanning simultaneously on both devices to avoid a misrepresentation due to the signal received from the remote device.
