1. A system for detecting operation of a cellular device onboard a mobile asset, comprising:

  • one of a directional and an omnidirectional receiving antenna configured to detect radio frequency energy produced by the cellular device onboard the mobile asset and communicate with a wireless processing unit onboard the mobile asset;

    a cellular device transmission detector onboard the mobile asset, the cellular device transmission detector configured to communicate with the antenna and the wireless processing unit and continually check a transmission status of the cellular device based on the radio frequency energy detected by the antenna; and

    a wireless processing unit onboard the mobile asset, the wireless processing unit configured to communicate with the cellular device transmission detector and receive an operating indication indicative of a first condition of the cellular device from the cellular device transmission detector on a second condition that the transmission status indicates that the first condition of the cellular device is operating.
