Which three IoT wireless mesh protocols are built on top of 802.15.4? (Choose three.)

  • Bluetooth Low Energy
  • near field communication
  • 6LoWPAN
  • ZigBee
  • Wi-Fi
  • Thread

Explanation: The IEEE 802.15.4 protocol was originally developed for use in personal-area networks (PANs) and consists of physical (PHY) and media access layer specifications. Due to the layered architecture, developers have been able to create diverse upper-layer protocols to allow ZigBee, Thread, and 6LoWPAN to run on top of 802.15.4.
