What is LPWA (low-power wide-area)?

A general term for wireless communication intended to send small amounts of data, such as sensor readings, from devices that run on batteries for years to places several kilometers or more away. Keeping the transmission rate low allows even weak signals to be received, extending the range. Some, such as LoRaWAN, use license-exempt bands (such as the 920 MHz band in Japan), while others, such as LTE-M and NB-IoT, use mobile phone bands.

Show answer and explanation

Answer: A. The transmission rate is low, but it covers a wide area of several kilometers or more with little power consumption

LPWA is a general term for wireless communication intended to send small amounts of data, such as sensor readings, over long distances from devices that run on batteries for years. Keeping the transmission rate low allows even weak signals to be received, extending the range. Some, such as LoRaWAN, use license-exempt bands (such as the 920 MHz band in Japan), while others, such as LTE-M and NB-IoT, use mobile phone bands.
