• Occupied bandwidth limit [kHz]
List box {possible values}, default = "25 kHz"
Occupied bandwidth is limited by granted radio channel. The standards supported by using individual
OBW limits are in Section 9.1, “ Detailed radio channel parameters” of this manual.
• Modulation type
List box {FSK, QAM}, default = "FSK"
○ FSK
Suitable for difficult conditions – longer radio hops, non-line of sight, noise / interferences on Radio
channel…
Note
FSK belongs to the continuous-phase frequency-shift keying family of non-linear modula-
tions. Compared to QAM (linear modulations), FSK is characterized by narrower bandwidth,
a lower symbol rate and higher sensitivity. As a result, the system gain is higher, power
efficiency is higher, but spectral efficiency is lower.
○ QAM
Suitable for normal conditions offering higher data throughput.
Note
QAM belongs to the phase shift keying family of linear modulations. Compared to FSK
(non-linear modulations), QAM is characterized by wider bandwidth. The spectral efficiency
is higher, power efficiency is lower and system gain is typically lower.
• Modulation
○ FSK modulations:
List box {2CPFSK; 4CPFSK}, default = "2CPFSK"
○ QAM modulations:
List box {DPSK; π/4DQPSK; D8PSK; 16DEQAM; 64QAM; 256QAM}, default = "DPSK"
• FEC
List box {2/3; 3/4; 5/6; Off}, default = "Off"
FEC (Forward Error Correction) is a very effective method to minimize radio channel impairments.
Basically, the sender inserts some redundant data into its messages. This redundancy allows the
receiver to detect and correct errors; used is Trellis code with Viterbi soft-decoder. The improvement
comes at the expense of the bitrate. The lower the FEC ratio, the better the capability of error correc-
tion and the lower the bitrate. Bitrate = Modulation rate × FEC ratio.
• Encryption
List box {Off; AES 256-CCM}, default = "Off"
AES 256-CCM (Advanced Encryption Standard) can be used to protect your data from an intrusion
on Radio channel. When AES 256 is On, control block of 16 Bytes length is attached to each frame
on Radio channel. AES requires an encryption key. The length of key is 256 bits (32 Bytes, 64 hexa
chars). The same key must be stored in all units within the network.
