How you learn
With a web browser, you attend one 2-hour live / interactive online class each week over a period of four weeks in our virtual classroom, where the instructor explains concepts and conducts demonstrations. You can ask the instructor questions during class sessions via chat integrated in the virtual classroom or between classes through email. As an option (included in the course tuition), you can complete practical hands-on experiments under the guidance of the instructor, reading assignments, and quizzes that reinforce the learning experience. Experiments include the use of RF measurement and packet analysis tools that you may already have (or you can use freely-available tools, such as NetStumbler and Wireshark). Ideally, you should also have an 802.11n access point or router (and computer with 802.11n client card) for most of the experiments.
Note: You should complete our Wireless LAN Fundamentals course before attending this course.
What you learn
This course is divided into four modules that provide extensive hands-on experiences implementing wireless LANs.
Module 1: Defining the Architecture for an 802.11n Wireless LAN
Learn how to specify the most effective 802.11n architecture as the basis for enterprise mobility, wireless IP telephony and vertical applications.
This module begins by describing how to define wireless requirements, which are important to know before getting too far with designing a wireless LAN. The module then focuses on how to design the wireless LAN access network and distribution system, with emphasis on high performance, scalability and redundancy. Students practice defining requirements and specifying wireless LAN architectures based on scenarios given in class (and your existing projects if desired).
Module 2: Performance and Roaming Considerations
Learn how to fine-tune an 802.11n wireless LAN to provide high-throughput, effective security and fast roaming.
This module describes applicable components and configuration settings for achieving high performance with 802.11n wireless LANs, effective security and fast roaming. Students practice defining necessary components and configuration settings for achieving various levels of performance and roaming.
Module 3: Wireless Security Considerations
Learn how to choose and configure an effective security solution for an 802.11n wireless LAN.
This module describes 802.11 / Wi-Fi security mechanisms,
802.1x port-based authentication, virtual private networks, intrusion detection systems,
rogue access point detection, and typical enterprise wireless security polices.
Students practice defining security solutions for various scenarios
given during class (and your existing projects if desired).
Module 4: Performing 802.11n Wireless Site Surveys
Learn how to identify the optimum installation locations for 802.11n access points.
This module explains the steps necessary for performing a site survey for 802.11n deployments. This includes test equipment, survey methods and strategies for providing signal coverage throughout different types of facilities and difficult-to-cover areas, such as elevators. Students practice performing site survey testing at their workplace, home, or other venue.
