Commercial radio technology has reached a new inflection point. The communications market and the underlying technology that provides voice and data services are evolving to provide higher data rates in the same frequency spectrum to ever more users. This seminar provides an overview of the changes occurring in the RF communications industry and the new technologies being developed: OFDM (Orthogonal Frequency Division Multiplex), OFDMA (Orthogonal Frequency Division Multiple Access), and MIMO (multiple-input, multiple-output). It covers the fundamentals of these new technologies, shows how these technologies are used in the WiMAX and WLAN standards, and discusses the test challenges and new test techniques for these technologies.
Participant Objectives:
This is the introductory seminar of a multi-part series on OFDM technologies and testing.
By attending this seminar you will learn:
- What OFDM is and how it differs from traditional digital modulation techniques.
- How OFDM is applied to WiMAX and WLAN technology standards.
- What OFDMA is, how it relates to OFDM, and where it is used.
- What MIMO is, how it differs from SISO, and how these apply to WiMAX and WLAN.
- Signal generation and analysis test instrumentation considerations for OFDM.
Target Audience:
This seminar is recommended for R&D engineers and manufacturering test engineers of wireless devices utilizing OFDM and MIMO technologies such as WiMAX, WLAN, LTE and UMB.
