Voice radio communication requirements

In Simple Terms

F1 teams can use radio systems to talk between the driver and pit crew, but these systems must be completely separate from the car's main computer and can only transmit voice—no other data like telemetry or performance information is allowed through the radio.

• Radio systems must be independent and not connected to the FIA Standard ECU (except for authorized connections)
• Voice communication only—no data transmission allowed through the radio system
• Prevents teams from using radio as a data channel to unfairly share performance information
• Ensures fair competition by limiting what information can be shared between car and pit crew
