Internet of Things (IoT) Practice Exam

To successfully send signals via radio stations, you should:

1. Increase power energy of radio station or decrease bandwidth

2. Decrease power energy of radio station or decrease bandwidth

3. Increase power energy of radio station or increase bandwidth

4. Decrease power energy of radio station or increase bandwidth

The correct answer is: Increase power energy of radio station or decrease bandwidth

To successfully send signals via radio stations, increasing the power energy of the radio station is essential for extending the transmission range and improving signal strength. Higher power levels enhance the ability of the signal to travel longer distances and penetrate obstacles, which is crucial in ensuring that the intended audience receives the signals clearly. On the other hand, decreasing the bandwidth can also contribute positively to signal transmission. Bandwidth refers to the range of frequencies over which the radio signal is transmitted. By reducing bandwidth, the signal can become more robust against noise and interference, leading to clearer reception. A narrower bandwidth can thus facilitate better communication within that limited frequency range, reducing the likelihood of overlap with other signals. The combination of increased power for long-range communication and decreased bandwidth for signal clarity makes this option particularly effective for successful signal transmission through radio stations.
