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. Please note that the center frequency must be equal for "master" and "slave" unit to establish the radio link. When a wireless link has been established Slave unit will continuously inherit radio frontend parameters from Master unit excluding frequency channel grid. So, if you change some values on Master they will be set on Slave automatically. |
Center frequency | Frequency should be selected manually in accordance with the actual frequency grid. The Quanta 70 accepts values i range 71000-76000. |
Power limit | This parameter limits the transmitter power, there are two modes:
Tx Power + Antenna gain |
Air frame
Parameter | Description |
---|---|
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. Following values are available: 0.1; 0.2; 0.5 ;1; 2; 5 ms. |
Downlink/Uplink ratio | Only for Master device. Allows to configure quotes for uplink and downlink directions. Available values depend from frame length. |
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 frequency range available to use. Values can be set as a range (71000-72500) or as a list (71500, 73400, 75600) with the step from 0,125 MHz till 10000 MHz.
