Unit role

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

Please note that the following settings must be equal for "master" and "slave" unit to establish the radio link:

  • Center frequency - there are two ways:
    • Manually via "Downlink center frequency" and "Uplink center frequency" parameters. In this case wireless link will be setup at once.
    • Automatically with "Automatic selection of center frequency" function. In this case frequency channel grids must be set on both units. At the initial phase Master unit will select its center frequency automatically from grid, after that Slave unit will scan frequencies from its grid and wireless link will be established when Slave will find the center frequency which Master operates on.
  • Channel width - should be the same and set manually on both units.

When a wireless link has been established Slave unit will continuously inherit radio frontend parameters from Master unit excluding frequency channel grids. So, if you change some values on Master they will be set on Slave automatically.

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.
Automatic selection of center frequency

There are several way to define center frequencies in Quanta 5:

  • Frequency selection off - center frequency will be set manually.
  • DFS and radar detection - center frequency will be set automatically according to frequency channel grids. In this mode Master unit will switch to the different frequency if high level interference or radar will be detected. Slave unit will switch too after some time.
Independent UL/DL center frequencies

Units may transmit on diffrerent center frequencies.

  • Enabled - uplink and downlink frequencies can be set to different values.
  • Disabled - uplink and downlink frequencies will be the same.
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:
