Shipcontroller uses a bidirectional radio communication system based on the standardized IEEE 802.15.4 protocol in the 2.4GHz band, offering numerous advantages:
- The bidirectional radio allows for continuous dialogue between the remote controls and the boat's transceivers. The radio link is permanently monitored, and the remote will immediately alert you in case of a radio link loss, loss of engine control, or other events or incidents.
- The 2.4GHz band and the 802.15.4 protocol are worldwide approved, unlike the 833MHz and 915MHz systems, which have significant regional restrictions. This means you can use your Shipcontroller system globally without legal limitations.
- Although it uses the same radio band as WiFi, the radio channels are different (there are 16) to avoid potential interference.
- It provides robust and reliable communication thanks to the DSSS (Direct Sequence Spread Spectrum) technique:
- It spreads the signal over a wider frequency band than necessary, distributing the energy across a broader spectrum, making it more resistant to narrowband interference.
- The signal is modulated using pseudo-random sequence codes. Only the receiver that knows this sequence can demodulate and recover the signal, reducing the possibility of interference or signal corruption.
- It offers an adequate data transmission speed to support a virtually unlimited number of control channels and the telemetry of navigation data.
- It supports point-to-point and multipoint configurations, allowing the implementation of the Shipcontroller NET system with multiple radio nodes and multiple remote controls.
- It supports 128-bit AES encryption for secure communications.
Each Shipcontroller system has a unique set of keys and identifiers, making it very difficult for the radio system to be intercepted: there are 10³⁸ possible keys.
