Course Length: 2 Days

Prerequisites: None

Course Objectives:

This course is designed to provide the student with required knowledge of and testing skills for Ethernet based services to wireless networks; commonly called Gig-E circuits. This course also teaches the student how to test Gig-E networks based on the RFC2544 standard, using popular test equipment including the QT600® network interface when appropriate. The course is approximately two days in length and a series of on-line webinars lasting two hours each are scheduled at regular intervals. Please visit our website for dates and tuition fees.
