ParameterDescription
Unit role

One units must be set to Master and the other one to Slave.

Dynamic frequency selection

Following modes are possible to operation:

  • Frequency selection off - the center frequency must be selected manually.
  • Mandatory DFS and radar detction - the least noisy frequency will be selected in accordance with the set frequency grid. The device will block the frequency in case it detects a radar.
  • Instant DFS - the least noisy frequency will be selected in accordance with the set frequency grid. The device will change frequency in case the strong interference appears.
  • Instant DFS and radar detction - the least noisy frequency will be selected in accordance with the set frequency grid. The device will change frequency in case the strong interference appears and block the frequency in case it detects a radar.
Note
titleNOTE

The radar detection mode is only available with "ETSI" regulatory domain. Instant DFS and radar detection are only available for the Quanta 5 family devices.

For detailed description of the listed modes proceed to the Instant DFS article.
Regulatory domain

Regulatory domain automatically limits the wireless device operation which is may be needed to meet the local law requirements. Each regulatory domain may limits the following parameters:

  • Range of available center frequencies
  • Requirement of use LBT (Listen Before Talk) technique.
  • Maximum EIRP (Equivalent Isotropically Radiated Power) value.
  • Requirement of use radar detection technique.
Fixed center frequency

Available only on the Slave unit.

  • Enabled - center frequency must be set manually on wich the Slave unit will operate.
  • Disabled - center frequenct will be selected automatically based on frequency channel grids.
Downlink/Uplink center frequencies

Allows to manually set the center frequency. The Quanta 5 family devices allow independent frequencies configuration for uplink and downlink streams. When same frequencies are used on both streams, transmission will be carried out in time division duplex (TDD) mode, when different frequencies are assigned for uplink and downlink directions can use the same frequency or differenttraffic, the transmission mode will change to hybrid frequency division duplex (H-FDD). The uplink frequency can be configured only on the master.

Note
titleNOTE

Downlink - the direction from Master to Slave, Uplink - the direction from Slave to Master. These directions are correct for the whole link and do not depend on the roles of the devices.

Power limit

This parameter limits the transmitter power, there are two modes:

  • Transmitter output power - limits the power of transmitter to the set value.
  • EIRP - limits the total system power calculated as: Tx Power + Antenna gain + Cable loss (an antenna gain and cable losses should be specified in the fields below).
