Course Title Broadband Wireless: Evolution, Technology, Infrastructure, and Regulation
Course type
Private Class
Aimed At

Those with some non-wireless technical background (such as in Math, Physics, or a branch of Engineering) and some prior exposure to telecommunications, e.g., technical managers, software and hardware engineers, marketing and sales professionals, OSS/BSS personnel and others who wish to learn more about wireless, with emphasis on the latest broadband wireless technologies.
Prerequisites

While there are no formal prerequisites for this course, technical background and some prior exposure to telecommunications will be helpful.
Course in a Nutshell

This three day course provides an intensive “technical light” overview of the evolution, market drivers, capabilities, and technologies of broadband wireless.

The course begins with a discussion of the principles that underlie cellular telecommunications, cellular system components (including base stations and towers), and network design issues. Discussed next is the evolution of cellular from GSM and CDMA to WCDMA/UMTS and CDMA2000. This is followed by a discussion of WiMAX and LTE, the current broadband wireless technologies. The course concludes with a look at spectrum regulation. Upon course completion, you will have acquired an understanding of how broadband wireless networks work and the forces that shaped their evolution.
Customize It!
