What Students are saying about this class:

  • "Wireless sensor network is very important for fog/edge computing. As part of IoT development team where our customers are using fog computing with sensors etc it is important to be aware with the sensor networks."
  • "Best parts: the Wireshark lab; the whiteboarding; and learning the characteristcs (pros/cons) of the different PHY technologies to the application."

Course Description:

The IEEE 802.15 group focuses on wireless personal area networks (WPAN). In particular, the 802.15.4 standard specifies the MAC and physical layer that provides support for low data rate transmission with low power utilization. There are several higher level specifications that have built sensor network solutions based on 802.15.4, including ISA100.11a, MiWi, WirelessHart, Wi-SUN, and ZigBee. This means that the 802.15.4 standard underlies most of the sensor networks used in home automation, smart utility networks, and industrial control and monitoring applications.

This course details the frequency bands and channels defined in 802.15.4-2003 and 2006 and used in ZigBee sensor networks. It compares and contrasts the operational differences between a beacon-enabled network and a non-beacon enabled network. If shows how a WPAN is formed and data is sent over the data link. It also describes the MAC and physical layer enhancements defined in 802.15.4e and g that are used in industrial sensor networks ISA100.11a and WirelessHart, as well as the smart utility and metering network Wi-SUN.

The course includes lab exercises to reinforce key learnings. The lab looks at the details carried in 802.15.4 beacon and data frames. They also illustrate how 802.15.4 sensor networks are formed, and enable sensors to subsequently connect and send data. The lab exercises use the Wireshark™ packet analysis tool, but no prior knowledge of Wireshark is required. Students are expected to install the Wireshark tool prior to attending the class.

Course Objectives:

At the end of this course, the learner will be able to:

  • Describe the evolution of the 802.15.4 specifications
  • List the different physical layers supported by 802.15.4 and .4g
  • Distinguish between the frequency bands and channels used by 802.15.4 based technologies
  • Discuss the pros and cons of using a beacon-enabled versus a non-beacon-enabled network
  • Define the addresses used by 802.15.4 to send and receive data frames
  • Understand how to establish and connect to an 802.15.4 network
  • Be familiar with the MAC and PPDU headers
  • Have insight into techniques and mechanisms used by 802.15.4 to reduce power consumption
  • Understand the enhancements added to the 802.15.4 specifications to support industrial and smart metering sensor applications
