Course Description:

Regulators in the US, Europe, and other regions around the world have allocated spectrum in the upper 5 GHz band for the deployment of Intelligent Transport System (ITS). ITS applications include traffic and safety alerts, local information and maps, and traffic management and control.

IEEE 802.11p defines how a Wi-Fi radio can be modified to support communications between vehicles, or between vehicles and roadside units. These enhancements support communications at vehicular speeds, over a greater range, making 802.11p the preferred technology over other sensor and radar technologies.

In the US and Europe the use of 802.11p has been mandated at the lower MAC and physical layer. At the higher layers, the US integrated the IEEE 1609 specification, and Europe the ETSI EN 302 specification.

This course starts with an overviews of the ITS activities around the world, including spectrum allocation and channel plans. It then details the 802.11p MAC and physical layer, explaining how great mobility and range is achieved. It also discusses QoS for control information and how urgent messages are handled.

The course then describes the higher layer IEEE 1609 protocol, features and capabilities. It details how 1609-4 supports operations in multiple frequency channels, and the primitives that provide support to the higher layer 1609.3 network services. It then covers the 1609.3 network services, including the WAVE Short Messaging protocol (WSMP), which is used to send control and safety messages. The course also discussed the routing advertisement messages that support the transmission of IPv6packets over the WAVE network.

Course Objectives:

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

  • Describe the challenges of implementing vehicular communications
  • List the different frequency channels available for vehicular communications
  • Distinguish between control and service channels
  • Define the physical layer changes to support great range and higher mobility
  • Understand how to connect to an 802.11p network and receive data
  • Have insight into the mechanism used by 802.11p to prioritize control traffic and emergency services
  • Be familiar with the IEEE 1609 standards including 1609.4 multi-channel operations and 1609.3 WAVEShort Messaging Protocol


The target audience for this course is anyone in Engineering, Test, Customer Support, Technical Marketing, or Sales and Marketing that requires an understanding of the IEEE 802.11p 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 protocol underpinning the Internet of Things (IoT)
  • Operations individuals that will provide configuration and support services
  • Network Design Engineers that need to understand Intelligent Transport System (ITS) applications
  • 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 vehicular communications
  • 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 the 802.11p Protocol or needing to understand the wireless technologies that are enabling the Internet of Things (IoT). The course does not require any prior wireless or Wi-Fi specific knowledge. However, it is highly desirable that learners have rudimentary knowledge of networking fundamentals. Familiarity with the Wireshark packet analysis tool is also beneficial.

Course Materials:

Students will be provided with a Course Student Guide via the Online School of Network Sciences.  From here they will have access to:
