Hands-On 802.11 Wireless Installation and Troubleshooting

Course Description

This course teaches installation and troubleshooting technicians the key elements needed for installing, testing, validating and troubleshooting WiFi equipment used inside and outside building for public and private hotspot services.

The course introduces the elementary principles of radio used in WiFi services. It teaches how to survey the location in order to position access points in the appropriate location and how to avoid contention with other 802.11 services. Students are taught how to select the appropriate antenna type for the selected location and position plant inside and outside as required.

The correct safety procedures and service configuration options will be learned in this course. Students will undertake practical exercises to install devices, undertake the appropriate configuration, measure signal strength, loss, Signal to Noise ratio and survey a site.

Students Will Learn

Recognize 802.11aBG And N Devices And Describe Their Wireless Characteristics
Configure Wireless Devices To Provide Service
Survey A Site For Delivery Of Quality Mobile Services
Select And Align The Appropriate Antennas For Key Application Conditions
Troubleshoot Wireless Problems
And More...

Target Audience
