Question
Which of the following is not LPWAN technologies?a.NB-IoTb.WiFic.SigFoxd.LoRa
Solution
The answer is b. WiFi. This is because WiFi is not a Low Power Wide Area Network (LPWAN) technology. LPWAN technologies are designed for long range communications at a low bit rate among connected objects, such as sensors operated on a battery. The main advantage of LPWAN technologies over WiFi is their power efficiency, long range, and lower cost. WiFi, on the other hand, is a high power, short range technology that is typically used for internet access in homes, offices, and public places.
