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."
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.
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
The target audience for this course is anyone in Engineering, Test, Customer Support, Technical Marketing, or even Sales and Marketing that requires an understanding of the Zigbee Protocol and seeks to comprehend the challenges of implementing the Internet of Things (IoT) as applied to their job function.
Ideal candidates are:
- Individuals looking to understand the wireless sensor protocola enabling the Internet of Things (IoT)
- Operations individuals that will provide configuration and support services
- Network Design Engineers that need to understand wireless low rate sensor networks
- Network Management individuals that are providing element and network management tools
- Technical sales individuals that must be able to correlate features with functionality
- Technical marketing individuals that want more than just a basic understanding of sensor networks
- Certification Track individuals that need to expand their knowledge and studies
- Network Administrators
This course is designed to appeal to anyone needing the skills and knowledge of the 802.15.4 protocol or needing to understand the wireless technologies that are enabling the Internet of Things (IoT). The course does not require any prior wireless knowledge. However, it is highly desirable that learners have rudimentary knowledge of networking fundamentals. Familiarity with the Wireshark packet analysis tool is also beneficial.
