IoT Wireless Technology Quick Guide

Wireless communication technology options used in IoT can vary significantly in terms of their maximum communication range, and the range often depends on factors like the transmission power, frequency band, and environmental conditions. Here's a list of IoT protocols sorted roughly by their maximum communication range, from shorter ranges to longer ranges:

Near Field Communication (NFC):

  • Range: Very short range, typically up to 10 centimeters.
  • Use Case: Mostly used for close-range contactless data transfer, such as mobile payments and smart access cards.

Bluetooth Low Energy (BLE):

  • Range: Typically up to 100 meters, but can vary depending on power settings and environmental conditions.
  • Use Case: Commonly used for short-range applications like wearable devices, beacons, and proximity sensing.
Zigbee:
  • Range: Typically up to 100 meters in open space, but can vary based on the Zigbee profile and physical environment.
  • Use Case: Suitable for home automation, industrial monitoring, and building management systems.
Z-Wave:
  • Range: Typically up to 100 meters, but the actual range can vary depending on the specific device and network configuration.
  • Use Case: Commonly used in smart home applications for devices like lights, locks, and sensors.
Thread:
  • Range: Typically up to 250 meters or more in open space.
  • Use Case: Used for home and industrial automation, particularly in mesh network configurations.

Wi-Fi (IEEE 802.11):
  • Range: Typically up to 100 meters indoors, but can be extended with repeaters and mesh networks.
  • Use Case: Commonly used for high-speed data communication in homes and businesses.
LoRaWAN (Long Range Wide Area Network):
  • Range: Varies depending on factors like frequency band and antenna height but can extend up to several kilometers.
  • Use Case: Suitable for low-power, long-range IoT applications such as agriculture, smart cities, and environmental monitoring.
Sigfox:
  • Range: Typically several kilometers, depending on network infrastructure and local conditions.
  • Use Case: Used for low-power, long-range IoT applications with a focus on low data rates.
NB-IoT (Narrowband IoT):
  • Range: Typically several kilometers or more, depending on the cellular network infrastructure.
  • Use Case: Utilizes existing cellular networks for IoT applications, offering extended coverage.
LTE-M (LTE for Machines):
  • Range: Similar to NB-IoT, with coverage extending over several kilometers.
  • Use Case: Leverages LTE networks for IoT applications with improved coverage and data rates.
Satellite Communications:
  • Range: Global coverage, suitable for remote and off-grid IoT applications.
  • Use Case: Used in applications where terrestrial networks are unavailable or impractical, such as maritime and remote monitoring.

    Please note that the actual range of these technologies can vary based on many factors, including regulatory limits, interference, and the specific hardware and network configurations used. When selecting a technology for your IoT project, it's essential to consider both the required range and other factors such as power consumption, data rate, and scalability to ensure it meets your project's needs.
