System and method to deterministically and dynamically prevent interference to the operation of safety-of-life radio equipment
First Claim
1. A system to deterministically and dynamically prevent interference to the operation of safety-of-life radio equipment in a vehicle, the system comprising:
- a radio management system in the vehicle; and
a wireless network frequency controller in the vehicle, the wireless network frequency controller communicatively coupled to the radio management system, wherein the wireless network frequency controller is operable to restrict the operational frequency of any one or more of internal wireless communication devices in the vehicle and any one or more of wireless sensors, in the vehicle, that are communicatively coupled to the wireless network frequency controller based on input from the radio management system, so that all the safety-of-life radio equipment is not being interfered with by the internal wireless communication devices and the wireless sensors that are communicatively coupled to the wireless network frequency controller.

Abstract
A system to deterministically and dynamically prevent interference to the operation of safety-of-life radio equipment in a vehicle is provided. The system includes a radio management system and a wireless network frequency controller communicatively coupled to the radio management system. The wireless network frequency controller is operable to restrict the operational frequency of any one or more of internal wireless communication devices and any one or more of wireless sensors that are communicatively coupled to the wireless network frequency controller. The restriction of the operational frequency is based on input from the radio management system. The restriction of the operational frequency ensures that all the safety-of-life radio equipment has interference-free operation with the internal wireless communication devices and the wireless sensors that are communicatively coupled to the wireless network frequency controller.
