The "Radio settings" section allows to configure radio parameters to establish wireless connection.
Radio settings are divided into the following categories:
Radio frontend
Parameter | Description |
---|---|
Unit role | One units must be set to Master and the other one to Slave. |
Dynamic frequency selection | Following modes are possible to operation:
NOTE 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. |
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:
|
Fixed center frequency | Available only on the Slave unit.
|
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 traffic, the transmission mode will change to hybrid frequency division duplex (H-FDD). The uplink frequency can be configured only on the master. NOTE 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:
|
Air frame
Parameter | Description |
---|---|
Channel width | Channel width, shoud be the same on both Master and Slave units. Available values: 3.5, 5, 7, 10, 14, 15, 20, 28, 30, 40, 50, 56 MHz. |
Frame length | Frame period affects the following wireless link metrics:
Please note that frame period value is strongly depends on interference conditions. If larger frames will be dropped the larger payload is lost and system performance is decreased significantly. If smaller frames will be dropped the smaller payload is lost. Available values: 1, 2, 5, 10 ms. |
Downlink /Uplink ratio | In automatic mode, the ratio changes dynamically in accordance with the transmitted traffic. Manual mode allows to set a fixed value. Available values depend from:
|
Automatic modulation and transmit power control
Parameter | Description |
---|---|
AMC strategy | There are following AMC strategies available:
|
Automatic transmit power control | ATPC allows to control transmitter output power automatically based on target RSSI value. If actual RSSI level is lower then unit increases transmitter output power of the remote unit and vice versa. ATPC could not set value that may exceed the "Power limit" value.
|
Target RSSI | RSSI value which will be used by ATPC as target. |
Frequency channel grids
The frequency grid allows to limit the scan range in case the center frequency is automatically selected. Also Instant DFS will use these restrictions when monitoring the noise situation. Narrow grid of available frequencies speeds up scanning and link establishing process. Manual center frequency selection will also be limited to the values indicated in the grid.
NOTE
Please note grids shoud be the same on both Master and Slave units.
