Lesson 1

Lesson 1: Building the Right Wireless Network, Downloadable Version

Deploying a wireless network does not start with access point, but with a clear definition of needs. In this lesson, you will learn the standard requirements of common environments, from enterprise office to Healthcare and outdoor.

Duration: 00:44:47  File Size: 67 MB


Lesson 2

Lesson 2: Application Specific Needs, Downloadable Version

In this lesson, you will learn to fine tune your design based on the target application requirements. TCP-based and UDP-based applications do not have the same network behavior, and each major application type translate into a slightly different network design.

Duration: 00:45:05  File Size: 67 MB


Lesson 3

Lesson 3: Determining the Right Cell Size, Downloadable Version

Once you know the type of network you want to deploy, you need to determine the size and shape of each cell. There are many factors to consider when creating this type of design, ranging from client and application parameters to common sense and industry best practices. This lesson will provide you with the parameters you need to change a flat AP service area into an efficient cell.

Duration: 01:05:16  File Size: 105 MB


Lesson 4

Lesson 4: Site Survey Techniques, Downloadable Version

Before deploying access points, you need to perform a site survey. This lesson will guide you through the elements you need to verify during the survey, and will provide information about the tools, techniques and tips commonly used to perform a successful site survey.

Duration: 00:50:12  File Size: 85 MB


Lesson 5

Lesson 5: How to Position an AP, Downloadable Version

Positioning APs takes into account the environment and the people. You would not place the APs the same way, or use the same antennas, to cover a corridor close to a parking lot, or to cover the same corridor close to a busy street. This lesson will give you the parameters you need to take into account when deciding of access point positions.

Duration: 00:59:02  File Size: 97 MB


Lesson 6

Lesson 6: Basic and Advanced Configurations, Downloadable Version

Once APs are physically deployed, you need to configure each AP parameters. This lesson will guide you through common good practices when configuring standard parameters (from channel to power, various intervals and security) and advanced parameters such as 802.11w, 802.11r, 802.11k or 802.11u.

Duration: 01:08:26  File Size: 115 MB


Lesson 7

Lesson 7: Deployment Good and Bad Practices, Downloadable Version

Years of Wi-Fi network deployments have shown that some parameters are optimal for small networks, and become issues in larger networks. Some possible configurations are simply bad practices that hinder the cell efficiency. This lesson will guide you through the good and bad of configurations that area available on most access points.

Duration: 00:56:42  File Size: 97 MB


Lesson 8

Lesson 8: When Things Work: Capturing and Understanding Frame Exchanges, Downloadable Version

Once your network is deployed, common tests can be used to validate that performances match your expectation. This lesson will guide you through these tests. This lesson will also use capture tools to offer the keys to understanding the wireless exchanges occurring in a cell, and assess if frames are exchanged normally, or if an issue is to be suspected.

Duration: 01:51:28  File Size: 207 MB


Lesson 9

Lesson 9: Capturing Exchanges for Troubleshooting-Wireshark and Excel Example, Downloadable Version

Once troubleshooting starts, free capture tools offer power means to export and reuse capture frames to understand the source of the issue. Poor signal? Interference issues? Application problems? The right utilization of the captures can provide the clues. This lesson will show you how.

Duration: 01:04:20  File Size: 137 MB


Lesson 10

Lesson 10: Troubleshooting Application Specific Issues, Downloadable Version

When issues hit several clients of the same type, capture analysis can reveal problems common to a vendor, a chipset, or an application. This lesson will give you specific keys to troubleshoot upper layer issues, but also to perform specific analysis when tackling VoWLAN or video over wireless issues.
