From the Editor's Desk: Communication is Vital

May 5, 2011
Author(s)
Catherine A. Remley
This is an Editorial for the June, 2011 issue of IEEE Microwave Magazine. Kate Remley, the Editor-in-Chief, writes about timely topics for the members of the Microwave Theory and Techniques Society (MTT-S).

Diode Power Probe Measurements of Wireless Signals

April 15, 2011
Author(s)
Catherine A. Remley, Hugo Gomes, Alejandro Testera, Nuno B. Carvalho, Monica Barciela
A new view of diode power probes is presented is this paper. It is shown analytically, by simulations and with measurements, that calibration procedures for diode power probes should be rethought when measuring new wireless standard type of signals. In

Measurements and Models for the Wireless Channel in a Ground-Based Urban Setting in Two Public Safety Frequency Bands

January 20, 2011
Author(s)
William F. Young, Catherine A. Remley, David W. Matolak, Qian Zhang, Christopher L. Holloway, Chriss A. Grosvenor, Camillo A. Gentile, Galen H. Koepke, Qiong Wu
We report on measured peer-to-peer (ground-based) wireless channel characteristics for an urban environment in two public safety frequency bands. Results are based upon measurements taken in Denver in June 2009. The public safety bands we investigated are

From the Editor's Desk: A Little Friendly Competition

This is an Editorial for the December, 2010 issue of IEEE Microwave Magazine. Kate Remley, the Editor-in-Chief, writes about timely topics for the members of the Microwave Theory and Techniques Society (MTT-S).

A Channel Propagation Model for the 700 MHz Band

September 1, 2010
Author(s)
Camillo A. Gentile, Nada T. Golmie, Catherine A. Remley, Christopher L. Holloway, William F. Young
Conversion from analog television in the United States combined with the appeal for broadband public safety communications is generating a lot of interest in the so-called 700 MHz band between 698-806 MHz. To our knowledge, no channel propagation model for

This is an Editorial for the August, 2010 issue of IEEE Microwave Magazine. Kate Remley, the Editor-in-Chief, writes about timely topics for the members of the Microwave Theory and Techniques Society (MTT-S).

Examining the True Effectiveness of Loading a Reverberation Chamber

July 29, 2010
Author(s)
Jason Coder, John M. Ladbury, Christopher L. Holloway, Kate Remley
In this paper we explore how placing the same amount of absorber in different locations within a reverberation chamber can have different loading effects. This difference can have a significant impact on measurement reproducibility, both for measurements

Bit Error Rate Measurements in Reverberation Chambers using a VSA

June 21, 2010
Author(s)
Catherine A. Remley, Sander Floris, Christopher L. Holloway
We discuss practical measurement implementation issues regarding the use of a vector signal analyzer for making bit-error-rate measurements in reverberation chambers. These issues include synchronizing the transmitted and received signals in spite of time

Reverberation-Chamber Test Environment for Outdoor Urban Wireless Propagation Studies

June 21, 2010
Author(s)
Helge Fielitz, Kate Remley, Christopher L. Holloway, Qian Zhang, Qiong Wu, David W. Matolak
We introduce a test environment to replicate the well-known clustering of reflections in power delay profiles from urban wireless propagation environments that exhibit late-time delays and reflections. The test set-up combines discrete reflections

Identifying RF Identification Cards from Measurements of Resonance and Carrier Harmonics

May 27, 2010
Author(s)
Henry Romero, Kate Remley, Dylan Williams, Chih-Ming Wang, Timothy X. Brown
We show that careful measurements of the unloaded resonant frequency and quality factor of radio frequency identification proximity cards allow identification of different card models and, for the set of cards we studied, identification with minimal error
