Paper Abstract

Overview of WiMAX Market Trend

This paper will provide an update on Mobile WiMAX market trend and a summary of Wave 2 capability. Looking beyond, the paper goes to explain in brief, what the evolution of Mobile WiMAX is like. It will introduce some of the future system profile features and standards that are currently under discussion and development, including Release 1.x and 802.16m.

MIMO Channel Modeling and Emulation Test Challenges

Modern radio designers have always looked for ways to improve spectral efficiency to transmit more bits per Hz without sacrificing signal quality. This paper covers how antenna technologies have evolved in recent years, including spatial diversity, spatial multiplexing, and beam forming, to improve signal quality and throughput. We will review common wireless propagation channel characteristics before focusing on the added complexity in MIMO channel emulation like calculating correlation matrices to simulate various channel conditions. This paper touches on MIMO theories and test challenges. Agilent MIMO solutions are discussed in the Mobile WiMAX paper.

What’s Next in 3GPP?

This paper discusses the trends of 3GPP mobile technologies: HSDPA, HSUPA, HSPA+ and LTE.

What are the requirements of LTE, and how do they differentiate from those of UMTS? How the physical layer procedures works? What are the difference between LTE & WiMAX?

This paper addresses the interests who needs to understand the concepts of 3GPP technologies. Our discussions will focus on latest 3GPP standards including physical frame structures on downlink (base station to mobile) and uplink (mobile to base station), physical layer procedures of air interface, modulations, timing & transmission power, initial cell search and random access procedures and so on.

The Mobile Digital Wireless Evolution as illustrated by DigRFv3 and MIPI

Digital wireless interface standards are emerging rapidly. What used to be the analog IQ interface between an RFIC and BBIC is being replaced with digital IQ. Additionally, with the explosion of mobile applications, for example, cameras and LCD displays, there are even more digital inputs and outputs (IOs) to contemplate. This session will discuss and present a clear test methodology for these 2 interfaces – DigRF v3 and MIPI. This can aid in making decisions on how to design more easily and effectively for test and measurement considerations.
