Question
George is a security professional working for iTech Solutions. He was tasked with securely transferring sensitive data of the organization between industrial systems. In this process, he used a short-range communication protocol based on the IEEE 203.15.4 standard. This protocol is used in devices that transfer data infrequently at a low rate in a restricted area, within a range of 10-100 m. What is the short-range wireless communication technology George employed in the above scenario?

Explanation
Zigbee is the correct answer. Zigbee is a short-range wireless communication protocol built directly on the IEEE 802.15.4 standard. It is specifically designed for devices that transmit data infrequently at low data rates, operating within a range of 10–100 meters - exactly matching the scenario described. Zigbee is widely used in industrial IoT, building automation, and sensor networks. The other options do not fit: MQTT is a messaging protocol (not a wireless communication standard), LPWAN (Low Power Wide Area Network) covers distances of several kilometers and is NOT based on IEEE 802.15.4, and NB-IoT is a wide-area cellular IoT technology - also not IEEE 802.15.4 and not short-range.
