What does LPWA stand for?

Last updated on 


LPWA stands for Low Power Wide Area. It refers to a category of wireless communication technologies designed to provide long-range communication with low power consumption for Internet of Things (IoT) and machine-to-machine (M2M) applications. Let's break down the term "LPWA" into its key components:

  1. Low Power:
    • LPWA technologies are designed to operate with low power consumption. This is crucial for devices that may need to operate for extended periods, such as battery-powered IoT devices or sensors in remote locations.
    • The low power requirement allows devices to have longer battery life, reducing the need for frequent battery replacements or recharging.
  2. Wide Area:
    • LPWA technologies are intended to provide communication over long distances, covering wide geographic areas. This is important for applications where devices are spread out or located in remote and challenging environments.
    • Unlike short-range wireless technologies like Wi-Fi or Bluetooth, LPWA is optimized for long-range communication.
  3. LPWA Technologies:
    • Several LPWA technologies exist, each with its own specifications and characteristics. Some common LPWA technologies include:
      • NB-IoT (Narrowband Internet of Things): This is a cellular-based LPWA technology standardized by the 3rd Generation Partnership Project (3GPP). It operates in licensed spectrum and is designed for low data rate, low power applications.
      • LTE-M (Long-Term Evolution for Machines): Also a 3GPP standard, LTE-M is another cellular-based LPWA technology. It provides a higher data rate compared to NB-IoT and is suitable for applications that require moderate bandwidth.
      • LoRa (Long Range): LoRa is a wireless communication technology that operates in unlicensed spectrum. It uses a chirp spread spectrum modulation to achieve long-range communication with low power consumption.
      • Sigfox: Sigfox is a proprietary LPWA technology that operates in the unlicensed ISM (Industrial, Scientific, and Medical) bands. It is designed for low data rate, low power applications.
