Which technology provides extended coverage for IoT devices?

The choice indicating the IoT-optimized GSM Network is correct mainly because this technology is specifically designed to extend the coverage and improve the connectivity options for IoT devices. These networks leverage existing GSM infrastructure while incorporating enhancements that make them more suitable for low-power, wide-area network (LPWAN) applications commonly used in IoT scenarios.

GSM-optimized networks prioritize factors such as extended battery life, efficient data transmission, and wider coverage that are essential for IoT devices that often operate in remote or underserved areas where traditional cellular connectivity might falter. Such networks are designed to facilitate thousands of devices communicating over a single base station at very low data rates, which is ideal for most IoT applications.

In contrast, options not selected like the Extended Coverage Mobile Network may also suggest coverage improvements, but they lack the specific IoT focus that makes the third choice more relevant. Similarly, the GSM Optimization Network and Enhanced Satellite Communication System do not target the unique requirements of IoT usage as effectively as an IoT-optimized GSM Network does, particularly in terms of power efficiency and coverage density.
