Systems, methods, and devices for enforcing do not disturb functionality on mobile devices

The transmissions of mobile devices in other vehicles will, obviously, be in the uplink bands monitored by the system. Again, it will be appreciated that such signals in other vehicles will vary as the vehicle in which the system antenna is located moves relative to such other vehicles. In contrast, the in-vehicle mobile device signal power will remain relatively fixed during uplink periods. The signal power of a mobile device can adjust depending on the distance of the cell tower with which it is communicating, but that signal power adjustment will typically be a relatively low difference over time and, thus, should not significantly impact any of the implementations described above.
Another implementation uses the antenna of the main controller or control device to monitor all uplink bands by itself, without the aid of any other external sources, to determine if any mobile device is present and cellularly-active instead of being off or in airplane mode. For example, if a company's policies state that ALL mobile devices must be turned off or in airplane mode during trips and the system detects that a user is not following this restriction, an alert can be sent by the system to the administrator or contact point for the company.
