Which technology is described as being closest to the standard of mobile technology?

• A. NSF
• B. Bluetooth
• C. LoRa
• D. RFID

Answer: (C)

Mobile IoT relies on connectivity that can travel with devices over large areas while keeping power use very low. LoRa fits this need as a standardized LPWAN technology that provides long-range wireless communication with very low energy consumption. Its LoRaWAN protocol supports roaming and handover between gateways, so moving devices can stay connected across wide regions without draining the battery. This combination—wide-area reach, low power, and a formal standard—fits the idea of a mobile technology standard better than the other options. RFID is limited to short-range identification, Bluetooth is designed for close-range links, and NSF isn’t a wireless communication standard.
