• Set the secret key word for encoding of the protocol messages
  • It must be up to 64 characters long, without spaces
  • It must be the same at both ends of the link

• Allows you to configure the channel width (in MHz). The possible values are: 10, 20 or 40 MHz

• Allows you to set the air frame period duration (in ms). The value range is 2, 4, 5 or 10 ms
  • A shorter frame period gives lower latency, but also has higher overheads
  • Using longer frame periods cuts down overheads, but increases the latency

Downlink Quota (%)

• Actual downlink/uplink ratio values through specifying the downlink subframe period relative to the whole frame
• Downlink Quota available values depend from:
  • Channel width
  • Short Cyclic prefix
  • Frame period
  • Max Distance

• Enable/disable short cyclic prefix option
• Cyclic prefix is used to mitigate inter-symbol interference due to multipath propagation environment
• Cyclic prefix size is always 1/8 for 10 MHz channel width

• Allows you to

• specify the maximum link distance (in

• kilometers). The

• possible values: from 1 to 100 in increments of 1 km
• The specified value must not be lower than the actual link distance, but it is recommended keep it as close as possible to the actual distance to avoid unnecessary overheads
• The recommended strategy is to set this parameter well above the actual distance after the units have been deployed based on the measured distance value taken from “xginfo stat” output

• Enable/disable control block boost option
• Control Block Boost improves link availability in the most difficult propagation and interference conditions due to the radio frame with control information transfer at duplicate transmit power

Downlink Center Frequency, MHz

(5 GHz units)

• Allows you to configure the frequency in MHz at which data will be transmitted
• The frequency selection is automatically blocked when "Instant DFS" and "Automatic frequency selection" options are enabled

Uplink Center Frequency, MHz

(5 GHz units)

• Allows you to configure the

• frequency in MHz at which data will be received
• The frequency selection is automatically blocked when "Instant DFS" and "Automatic frequency selection" options are enabled

Center Frequency, MHz

(6 GHz units)

• Allows you to configure the center frequency

• Allows you to configure the transmit power level (in dBm). The value range is 0…27 dBm in increments of 1 dBm

• Not available in case of Instant DFS option disabled

• Allows you to select the AMC algorithm strategy:

• • “conservative” assumes using higher CINR thresholds in order to minimize the error rate

• • “aggressive” lowers the thresholds in order to use higher modulation levels and thus increase the throughput

• • “normal” represents a balance between the error rate and throughput values

• Allows you to configure the

• maximum MCS that can be used:
  • QPSK 1/2
  • QPSK 3/4
  • QAM16 1/2
  • QAM16 3/4
  • QAM64 4/6
  • QAM64 5/6
  • QAM256 6/8
  • QAM256 7/8
  • QAM256 30/32
  • QAM1024 8/10

• ATPC Master
  • The master unit manages the transmit power of the remote unit in order to achieve the target RSSI value of its own receiver
• ATPC Slave
  • The slave unit corrects the transmit power of its own transmitter according to the master unit directions
• In general "ATPC Master" and "ATPC Slave" are not related to the "master" and "slave" parameters. The same unit can be as "ATPC Master" and "ATPC Slave"

• The RSSI value of the master tries to engage the target range, the center value of which is the "Target RSSI"
• Practical range: from -20 to -70 dBm (the actual: from -40 to -70 dBm)
