Quanta 5: Installation and Configuration



Quanta 5 diagnostic tools area: a dashboard, a system log, in some cases, the Alignment and Spectrum analyzer utilities. More detailed information about these tools you can find in Mounting and Antenna alignment.


This section is intended to provide the main information about the wireless unit operation. 

The Dashboard displays a read-only summary of the current link status information, local and remote device signal strength, capacity for downlink and uplink, current values of the basic configuration settings and Ethernet network status.

The “Radio” tab displays the current settings of the wireless connection, as well as the link load in the uplink and downlink directions.

In the "Wired interface" tab, the Ethernet interface status can be monitored, as well as duplex mode and traffic load for reception and transmission. The wired interface statistic is available on the right side, it can be reset by the "Clear counters" button.

  • Runt packets - packets less than 64 bytes in size.
  • Oversize packets - pckets larger than 1518 bytes.
  • FCS errors - packets dropped due to checksum mismatch.
  • Port overflow errors - packets dropped due to port buffer overflow.
Modulation and Coding Scheme

On Quanta 5 device, modulation and coding schemes are selected independently for each channel (uplink and downlink) for both polarizations. Current modulation for each channel is displayed in the MCS subsection.

Received Signal Strength Indicator

The RSSI indicator displays the received signal level for each channel (uplink and downlink) and both polarizations. Available values:

  • -90...-80 dBm - close to the receiver sensitivity level, only the lowest modulations are available. 
  • -80...-60 dBm - average input range.
  • -60...-40 dBm - the recommended range for achieving best performance.
  • >-40 dBm - input signal level is too high.

Error vector magnitude - indicator of the measured input signal quality, telling how far are the received constellation symbols compared to the ideal symbols of the constellation. The parameter value must be as high as possible in absolute value. The recommended level should be more than 21 dB in absolute value.

Retries and Frame loss

Retried and lost packets need also to be tracked. Retries should tend to zero, link with the retries value more than 5% should not be allowed to operation.

System Log

An important tool in troubleshooting, which allows to track changes that preceded the link degradation. To view the system log, go to "Service" → "Maintenance" → "Device information" and click the "Show log" button.
