In one aspect, a controller and one or more noise generation units can be used to inhibit passenger devices from connecting to ground-based cellular stations while on-board. The noise generation unit can be configured to generate a noise signal. If a loss of power to an on-board cell station is identified, the noise generation can generate a different noise signal in response. ## Claims ### Claim 1 A method for monitoring a cellular network on board an aircraft, comprising: providing a network control unit comprising a general control system operatively linked to a noise generation unit;
