Engineers with GSM/GPRS experience who wish to learn about EDGE. The standard presentation of this course assumes a bachelor of science in Electrical Engineering, Mathematics, Physics, or a related subject along with an appropriate background in communications.
- Prerequisites
-
- GSM: Network Architecture, Operation, and Design (5 day(s), GSM-I)
- GPRS: Network Architecture, Operation, and Design (3 day(s), GPRS)
- Working knowledge of wireless network structure and operation, RF propagation and fading issues, and link budget analysis
- Working knowledge of packet switching and associated networking problems and solution approaches
- At least two years experience in the design and optimization of a wireless network using any major technology
- Course in a Nutshell
-
GPRS is the pivotal technology that brought packet switching to the world of mobile communications. It’s no secret that GPRS suffers from some significant drawbacks, for which it is sometimes unjustly ‘blamed’. What we fail to recognize is that GPRS was meant to be a stepping stone to bigger and better things. EDGE, often refereed to as “Enhanced GPRS” is that next step up! Edge overcomes the limitations of GPRS in truly unique ways, the discussion of which constitutes the content of this course.
If you have taken our GPRS course or are otherwise familiar with the technology, you’re well aware of the technology’s shortcomings and the fact that some of them are both serious and not solvable within the GPRS framework. After completing this course, you will know how EDGE tackles those problems, very effectively at that. You will learn what options are available to the network optimization processes and their advantages and disadvantages.
- Customize It!
-
Customize this course to your specific needs at little-to-no additional cost. We offer distinct versions tailored for:
- Network design and optimization engineers
- Equipment or application designers
- Less technical audiences such as managers, executives, business planners, sales and marketing specialists, and operations and support personnel
You can also combine this 2-day EDGE course with its prequel, the 3-day GPRS course, for an integrated five-day presentation. Ask us about the ‘combo’ discount.
