a cellular network is expensive, especially with many IoT devices.

A. signaling

B. security

C. bandwidth

D. power consumption

Answer: Option D

Solution(By Examveda Team)

In the context of Internet of Things (IoT), the use of a cellular network can be costly, particularly when dealing with a large number of IoT devices. One of the significant contributing factors to this expense is the power consumption of the devices. Cellular communication requires energy for transmitting and receiving data, which can drain the limited power resources of IoT devices, especially those with small batteries or located in remote areas.

This power consumption issue often necessitates frequent battery replacements or recharging, leading to increased operational costs and maintenance efforts. In scenarios where IoT devices are deployed on a massive scale, managing their power needs becomes a critical concern to ensure the sustainability and cost-effectiveness of the IoT deployment.

Therefore, the correct answer is Option D: power consumption. Options A (signaling), B (security), and C (bandwidth) are also relevant factors to consider in IoT deployments but are not directly linked to the statement about the costliness of cellular networks for IoT devices.
