Internet of Things (IoT) Practice Exam

In IoT networks, what are we seeking in terms of signal transmission?

1. Sending signals far, using low power energy

2. Sending signals near using low power energy

3. Sending signals far, using high power energy

4. Sending signals near, using high power energy

The correct answer is: Sending signals far, using low power energy

In IoT networks, the primary goal for signal transmission is to efficiently send signals over long distances while minimizing power usage. This is particularly important in IoT applications, where devices are often battery-operated and require energy efficiency to prolong their operational lifespan. By using low power energy, IoT devices can communicate effectively without draining their power sources quickly, thus making them more sustainable and effective in various applications ranging from smart homes to industrial environments. The ability to send signals over a long range is particularly beneficial in scenarios where devices may be spread out across a wide area, like in agricultural sensors or citywide smart infrastructure systems. This balance of range and energy efficiency is crucial for the scalability and practicality of IoT solutions. As such, the choice of sending signals far while using low power energy aligns perfectly with the overarching objectives in the development and deployment of IoT technology.
