Frequency Hopping

Frequency hopping is a technology used in remote controlled race cars to ensure a stable and interference-free connection between the car and the controller. It works by allowing the car to rapidly switch between different radio frequencies in a pre-determined sequence. This sequence is carefully planned to avoid interference from other devices operating on the same frequency band.

Here’s how it works:

  1. The car and controller are equipped with a frequency hopping system that allows them to communicate on different frequencies in a pre-determined sequence.
  2. When the car is powered on, it automatically starts hopping through the available frequencies in the sequence.
  3. The controller sends a signal to the car, instructing it to switch to a specific frequency in the sequence.
  4. The car receives the signal and switches to the specified frequency, allowing the controller to send commands to it.
  5. The car continues to hop through the sequence, constantly monitoring for any interference. If interference is detected, it will automatically switch to a different frequency in the sequence.

By using frequency hopping, remote controlled race cars can maintain a stable and interference-free connection, even in environments with many other devices operating on the same frequency band. This ensures that the car can be controlled accurately and reliably, providing a better overall racing experience.
