Course Description:

This course is about how wireless networks will enable the Internet of Things (IoT).  Low power and Lossy Networks (LLNs) are networks of embedded devices, such as sensors, that have limited power, memory, and processing capability. These low cost devices are often battery operated and can only handle limited amounts of data. Due to the embedded nature of these devices, they are subjected to a high variance of environmental factors, interference, and noise. Network protocols must be designed to operate effectively in what is referred to as a “lossy” environment where transmitted messages are often lost.

The growing importance of LLN becomes apparent when you look at how LLN networks will be used. Applications include the Internet of Things (IoT), Machine to Machine (M2M) communications, and Smart City. In other words, the number of devices that connect these networks will be in the tens of billions.

Using IP as the core network protocol for LLN has distinct benefits. Most important is that it enables these devices to connect to the Internet. However it also allows these devices to leverage standard Web-based interfaces and standard management tools, as well as being able to leverage a suite of support protocols such as IPsec for security and ICMP for control messaging.  However TCP/IP protocols are not designed to support low power devices that operate in a highly lossy environment. This course will take the learner through the different protocols that make up this exciting world of interconnected things. This course will discuss:

  • The wide variety of different wireless protocols used to connect these devices to the Internet:

    • Bluetooth Low Energy (BLE)

    • IEEE 802.15.4 Low Rate Wireless Personal Area Networks (LR-WPAN) 

    • Long Range Wide Area Network (LoRaWAN)

  • The higher layer protocols that allow applications to run on these devices:

    • ZigBee

    • WiSUN

    • Wireless HART

    • ISA100

  • Protocols that enable IP to work effectively in a lossy environment:

    • IPv6 over Low power WLAN’s (6LoWLAN)

    • Routing Protocol for LLN (RPL)

The course will include labs on 802.15.4, ZigBee, 6LoWPAN, and RPL. Learners will use Wireshark to explore the details of these protocols, look at message flows, and discuss the impact on network performance.  This is a lab based course. 

This course also provides an introductory overview of the important application protocols emerging in this segment to support Web services, sensor applications, metering, industrial control, and smart city solutions.


Course Objectives:

  • Become informed as to why LLNs are underpinning the evolution to the Internet of Things
  • Discover the challenges of providing connectivity to devices that are operating in highly variable and lossy RF environments
  • Build a solid understanding of the wireless protocols that have been defined to support connectivity of low power devices
  • Understand the different mechanisms important for enabling sensors and other low power devices to connect to the Internet
  • Reveal what higher layer protocols are enabling applications and services to run over wireless Low Power and Lossy Networks (LLN)
  • Gain insights into the importance of LLNs and how we can better manage that importance in our job functions


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 fundamental operations of Wireless Low Power Lossy Networks (LLN’s) 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 protocol underpinning the Internet of Things (IoT)
  • Operations individuals that will provide configuration and support services
  • Network Design Engineers that need to understand Wireless Low Power Lossy Networks (LLN)
  • 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 LLN
  • Certification Track individuals that need to expand their knowledge and studies
  • Network Administrators

Course Prerequisites:

This course is designed to appeal to anyone needing the skills and knowledge of Wireless Low Power Lossy Networks 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 IP networking. Familiarity with the Wireshark packet analysis tool is also preferred.
