Course Title
Everything Wireless: RF/Cellular Basics, WiFi, Bluetooth, WiMAX, CDMA, GSM/GPRS/EDGE, UMTS/HSPA, and LTE
Course type
- Aimed At
-
Those whose job involves working with a variety of wireless technologies or who require a broad, technical understanding of the entire field of fixed and/or mobile wireless. This includes individuals in national defense, homeland security, technical investigations, and the private sector.
- Prerequisites
-
The course assumes that the audience is well versed with Physics, Mathematics, and general engineering principles but does not have a great deal of prior experience with wireless communications technologies.
- Course in a Nutshell
-
We designed this course for the unique needs of those who are new to, or can use a refresher on, the wireless technology, have some technical (engineering or Mathematics/Physics) background, and need a comprehensive course covering the basic principles of RF/wireless as well as all of the current and emerging wireless technologies including GSM/GPRS/EDGE, CDMA, WiFI, Bluetooth, WiMAX, UMTS/HSPA, and LTE. Also included is a discussion of the location based technologies and security issues.
- Customize It!
-
We can customize this course, usually at little to no added cost, in a number of ways that include:
- If you are familiar with some aspects of wireless, such as RF propagation or wireless network architecture, we can omit or shorten their discussion.
- If you are interested in some technologies more than others, we can adjust the emphasis placed on the various topics or build the course around the mix of technologies of interest to you (including technologies other than those listed as part of this outline).
- If your background does not include Mathematics and Physics and you want us to present the course in a non-technical manner, we can do that as well.
