Anti-interference capabilities are the lifeline for unmanned systems to maintain reliable connectivity and autonomous control in complex environments. They effectively resist signal interference from other devices, the electromagnetic environment, or malicious attacks, ensuring the real-time and accurate transmission of critical commands (such as steering, obstacle avoidance, and emergency stops), while also guaranteeing the stable and uninterrupted return of high-definition video and sensor data. This not only directly determines mission success or failure but also serves as a core safety cornerstone to prevent system loss of connectivity, loss of control, and even collisions or crashes.
IWAVE’s wireless communication data links deliver the strong anti-jamming performance based on the following technologies:
Intelligent Frequency Selection (Interference Avoidance)
Intelligent frequency selection (interference avoidance) is an emerging anti-interference technology that effectively avoids interference and maximizes the reliability and stability of wireless transmission.
The key to IWAVE's unique intelligent frequency selection (interference avoidance) lies in three key processes: interference detection, decision-making, and handover execution. Interference detection involves real-time monitoring of interference and background noise at each frequency during normal communication, providing the foundation for decision-making. Decision-making is performed independently by each node, selecting the optimal frequency based on optimizing its own reception performance. Handover execution occurs after the optimal frequency is selected. This handover process prevents data loss, ensuring stable and continuous data transmission.
IWAVE's unique intelligent frequency selection (interference avoidance) technology enables each node to dynamically select different optimal frequencies for inter-frequency networking, thereby optimizing overall network performance and effectively avoiding interference.
Frequency Hopping
Frequency hopping is the most commonly used communication technology for anti-interference and anti-interception.
In frequency-hopping communication, both parties change frequencies according to a pre-agreed pseudo-random hopping sequence. To ensure normal communication between the radios, the frequency-hopping system must first synchronize the hopping pattern. Then, the transceiver must hop to the same frequency at the same time according to the agreed-upon hopping sequence to transmit bursts of wireless data.
Frequency hopping provides frequency diversity and interference mitigation, effectively improving the transmission quality of wireless links and reducing the impact of interference on wireless transmission. Even if some frequencies are interfered with, normal communication can still be carried out on other unaffected frequencies. Furthermore, compared to fixed-frequency communication, frequency-hopping communication is more discreet and difficult to intercept. Without knowing the hopping pattern and hopping period, it is difficult to intercept the corresponding communication content.
Interference Prevention
Interference prevention is the integrated application of multiple anti-interference technologies. Its primary purpose is to mitigate various types of interference during communications. Even in high-interference environments (with a 50% probability of transmission interruption), it ensures stable network connections and data transmission.
This superior capability can be combined with frequency hopping and other communication modes to ensure system robustness.
