In a marine sanctuary, an oceanographic telemetry network uses surface buoys to transmit environmental data via amplitude modulation (AM) to a central coastal receiver. The network consists of 18 high-priority deep-sea buoys and 12 secondary coastal weather buoys, all operating within the same region.
The regulatory agency has allocated a frequency band for these AM transmissions from 450 kHz450\text{ kHz}450 kHz to 850 kHz850\text{ kHz}850 kHz.
Determine whether all 30 buoys can transmit simultaneously with a maximum baseband signal frequency of 8 kHz8\text{ kHz}8 kHz per buoy without spectral overlap. Support your answer with calculations of both the available bandwidth and the total required bandwidth, and state the communication consequence if this setup is attempted.
