At the offshore wind farm 'Aeolus Prime', an array of 18 turbine sensors and 12 marine environmental buoys transmit raw acoustic and vibration telemetry data back to a central monitoring station using amplitude modulation (AM).
The licensed frequency spectrum allocated for these marine telemetry signals is restricted to the range from 450 kHz450\text{ kHz}450 kHz to 850 kHz850\text{ kHz}850 kHz.
Determine whether all 30 telemetry nodes can transmit high-resolution data with a maximum modulating signal frequency of 8 kHz8\text{ kHz}8 kHz simultaneously without overlapping. Support your answer with calculations for both the available and required bandwidth, and state the physical consequence if this configuration is attempted.
