Real-time 4x4 MIMO-OFDM Testbed

Peter Jan Lüthi from  Switzerland has to his credit this Ph.D. Thesis - VLSI Circuits for MIMO Preprocessing.This is related to design, implementation and demonstration of suitable algorithms for MIMO wireless communication.

Real-time 4x4 MIMO-OFDM Testbed

"The latest mobile applications and the growing number of wireless users are increasing the demand for high-throughput wireless access solutions. Multiple-input multiple-output (MIMO) technology combined with orthogonal frequency-division multiplexing (OFDM) constitute today's most promising approach to exploit the limited radio frequency resources in a highly efficient way. "

Personal Telco Project - Oregon

The Personal Telco Project is a 501(c)(3) non-profit organization located in Portland, Oregon dedicated to the idea that users have a central role in how their communications networks are operated.

"We are a volunteer group of Portlanders who believe that 802.11 (wireless networking, or Wi-Fi) technology is both cool and empowering. "

Personal Telco Project - Oregon

"We started, in 2000, by turning our own houses and apartments into wireless hotspots (also referred to as "nodes"), and then set about building these nodes in public locations such as parks and coffee shops. Currently we have over 100 active nodes, and we eventually would like to cover the entire city of Portland, Oregon with even more."

Anritsu Corporation - Test and Measurement

Information network test & measurement for mobile & internet, RF&Microwave solutions, fibre-optic telecommunications and industrial solutions.

Anritsu Corporation - Test and Measurement

Anritsu Corporation is a Japanese company specializing in the test and measurement equipment market. Products include microwave, radio frequency (RF), and optical signal generators, spectrum analyzers, and network analyzers.

VectorStar  MS4640B Series Anritsu

The VectorStar family is Anritsu's Premium VNA line, providing the highest overall performance on a modern platform. The MS4640B VectorStar VNA offers the broadest coverage in a single instrument, 70 kHz to 70 GHz. The additional two decades at the low end are even more impressive than the guaranteed 70 GHz coverage on the high end.

VectorStar Family of RF, µW, mmW VNAs MS4640B Series

The Anritsu MS4640B Vector Network Analyzer offers a new level of performance for device modeling engineers struggling to accurately and reliably characterize their devices, for R&D engineers pushing the last fraction of a dB out of their state-of-the-art designs, and for the manufacturing engineer trying to maximize throughput without sacrificing accuracy

1931- Anritsu Electric Corporation was established by the merger of Kyoritsu Electric and Annaka Electric
