Answers
D.
2G/2.5G
Suggested answer: C

Explanation:

2G/2.5G: 2G connectivity remains a prevalent and viable IoT connectivity option due to the low cost of 2G modules, relatively long battery life, and large installed base of

2G sensors and M2M applications.

3G: IoT devices with 3G modules use either Wideband Code Division Multiple Access

(W-CDMA) or Evolved High Speed Packet Access (HSPA+ and Advanced HSPA+) to achieve data transfer rates of 384Kbps to 168Mbps.

4G/Long-Term Evolution (LTE): 4G/LTE networks enable real-time IoT use cases, such as autonomous vehicles, with 4G LTE Advanced Pro delivering speeds in excess of

3Gbps and less than 2 milliseconds of latency.

5G: 5G cellular technology provides significant enhancements compared to 4G/LTE

networks and is backed by ultra-low latency, massive connectivity and scalability for

IoT devices, more efficient use of the licensed spectrum, and network slicing for application traffic prioritization.
