IoT Connectivity Of Low-Power Wide-Area Networks

IoT Connectivity of Low-Power Wide-Area Networks


There is an apparently vast number of options of connectivity of the Internet of Things (IoT). Some of the possible ways to connect a sensor or device to the internet are included;

  • Cellular
  • Satellite
  • WiFi
  • Bluetooth
  • RFID
  • NFC
  • Ethernet

In this article, we will learn about Low-Power Wide-Area Networks (LPWANs).


A low-power Wide Area Network (LPWAN) is a technology related to a wireless wide area network. That connects low-bandwidth, battery-powered devices with low bit rates over long ranges. We have to decrease the amount of data that we’re sending to increase range while keeping low power consumption.

LPWANs conduct minor amounts of data. That permits them to operate at very low power with ranges in miles rather than feet. For instance, a moisture sensor for agricultural drives doesn’t essential to spend a lot of data, possibly just a single number every few hours. We as well don’t want this sensor to consume a lot of power as it needs to run on a battery.

WiFi and Bluetooth absent the range ever since agriculture covers a wide area. LPWANs are very advantageous for many IoT applications. They permit tons of sensors and devices to gather and send data in excess of broad areas through long-term years on battery life. Though they can’t send abundant data, utmost sensors don’t need to.

IoT Connectivity Of Low-Power Wide-Area Networks

How does LPWAN permit low power consumption over a wide area?

  • There must be small and simple messages sent over LPWAN.
  • These messages may be communicated over a distance without a large power source due to their simplicity.
  • Decreasing the amount of data sent means lower energy at the range for machines.
  • LPWANs send and receive small packets of information at rare intervals.
  • Sensors and devices may send data over miles of range instead of feet.
  • That can last for years on the battery as an alternative of weeks or months.
  • Sometimes messages that are transmitted over LPwan aren’t received by the gateway.
  • We can commonly be overcome this by sending several messages.
  • Another way we can overcome this is by adding additional gateways to the network.
  • These solutions have power and economic costs separately.

LPWANs role in Internet-of-Things (IoT)

  • LPWAN technology consequently plays a vital role in allowing the Internet of Things.
  • These networks make it easy to have a lot of thousands of sensors and devices gathering and sending data at a lower cost.
  • They also make it possible for over longer range, and with better battery life than other connectivity options.

Some use cases comprise:

  • A car auction lot or dealership — sensors are located on vehicles to track their location and status in real-time.
  • A parking garage — sensors notice when spots are open, directing a simple Yes or No message simply when that value changes.
  • A school building — battery-powered locks may be remotely activated or deactivated, serving with overall security and crisis situations.
  • A city — waste containers all over a city may send alerts when they’re near to being full, letting for more effectual garbage collection.

Types of LPWANs

  • LPWAN is a group of many low-power, wide area network technologies.
  • It may use licensed and unlicensed frequencies.
  • It comprises proprietary or open standard options.
  • Sigfox is the proprietary, unlicensed widely deployed LPWANs today.
  • RPMA (Random phase multiple access) is a proprietary LPWAN from Ingenu Inc.
  • It has greater power consumption than other LPWAN options.
  • Similarly, the unlicensed LoRa transmits in many sub-gigahertz frequencies.
  • It enables users to define packet size.
  • SIG is the weightless type of LPWAN. It has developed three standards:
  • The unidirectional Weightless-N
  • Bidirectional Weightless-P
  • Weightless-W
  • Some sellers, with Orange and SK Telecom, are deploying both licensed and unlicensed technologies to capture equally markets.

Additional LPWAN technologies

  • GreenOFDM from GreenWaves Technologies
  • DASH7 from Haystack Technologies Inc.
  • Symphony Link from Link Labs Inc.
  • ThingPark Wireless from Actility
  • Ultra Narrow Band from different companies with Telensa, Nwave and Sigfox
  • WAVIoT


  • LPWANs allow a number of M2M and IoT applications.
  • Several of which were before constrained by budgets and power issues.
  • Picking an LPWAN to be contingent on the detailed application.
  • That is the preferred speed, data quantities and area covered.
  • LPWANs are top right for applications needful infrequent uplink message delivery of lesser messages.
  • Best LPWAN technologies also have downlink capabilities.
  • LPWANs are usually used in the following applications;
  • Smart metering
  • Smart lighting
  • Asset monitoring and tracking
  • Smart cities
  • Precision agriculture
  • Livestock monitoring
  • Energy management
  • Manufacturing
  • Industrial IoT deployments.
