Internet of Things (IoT) Practice Exam

What kind of power do IoT networks generally require?

1. Low power energy

2. High power energy

3. Send signals not far from transmitter

4. A and B are correct

The correct answer is: A and B are correct

In IoT networks, the general requirement for power is primarily low power energy. This is because many IoT devices are designed to operate on minimal energy due to their often remote placement, limited battery capacity, and the need for prolonged operational life between battery replacements or recharges. Low power consumption is crucial for enabling devices to function effectively over extended periods without frequent maintenance. While there are scenarios where some IoT applications may require higher power, such as in networks involving industrial IoT devices which might require more robust processing capabilities, the majority of IoT devices are indeed optimized for low power operation. This is part of their design to facilitate connectivity in environments where power sources might not be readily available, leveraging technologies such as Low Power Wide Area Networks (LPWAN) and energy-efficient protocols. As for the aspect of signal range, IoT devices typically send signals that do not need to cover extensive distances because they are often part of a denser network structure. They can frequently rely on proximity to gateways or other devices to transmit data effectively within a localized area, thus necessitating less power for short-range communication. Therefore, the answer highlights the understanding that while IoT networks may sometimes utilize various power levels depending on the specific use case, they primarily aim for efficiency
