Mobile asset cellular device transmission detection system and method
First Claim
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.

Abstract
A mobile asset cellular device transmission detector system and method comprises a mobile asset cellular device transmission detector, a wireless processing unit, an event recorder, and a digital video recorder. The wireless processing unit includes event recorder interface software, digital video recorder interface software that obtains data from the digital video recorder, wireless navigation (Wi-Nav) software that obtains data from the Wi-Nav, global positioning system (GPS) software that obtains data from a GPS and geo-fence software. The cellular device transmission detector continually checks for cellular device transmissions within a mobile asset and whether those transmissions were associated with an impact, rollover, operator action or geo-fence defined location and/or boundary. When a cellular device transmission was made, the wireless processing unit triggers an episode and sends event recorder information, GPS location and speed, audio and video recordings, and impact and rollover information to a back office.
