Which statement about bandwidth and range is incorrect?

• A. NFC has Low BW and Low Range
• B. Mobile 4G/LTE has Low BW and Low Range
• C. Bluetooth has Low BW and Low Range
• D. Lora has Low BW and Low Range

Answer: (B)

Bandwidth and range describe how much data can be sent per second and how far a signal can travel. LTE/4G is built for high-speed data and wide coverage, using cell towers to connect devices over large areas. That means it has high bandwidth and a broad range, not low. So the statement claiming mobile 4G/LTE has low bandwidth and low range is incorrect. The other technologies fit their typical profiles: NFC is near-field with very low data rates and a few centimeters of range; Bluetooth generally offers short-range communication with modest data rates; LoRa uses very low data rates but can achieve long-range connectivity.
