Estimating RF Spectrum Utilization

|
RF spectrum utilization offers information about how much and how often a given licensed or unlicensed spectrum is used. Methods and techniques for estimating the RF spectrum utilization are needed either for spectrum sharing, assessing harmful interference within licensed/unlicensed frequency bands or for auditing the radio environment before commissioning new access nodes [1-3,6]. The paper addresses the spectrum clearance estimation and defines the associated metrics. Results pertaining to a spectrum clearance campaign in the 900 MHz and 2.5 GHz for both stationary and mobile cases are included ...Learn More

Natalie Zelkin, M.S., M-IEEE - a senior member of WI-LCC's engineering faculty, has almost fifteen years of progressive engineering and management experience in the field of wireless communications.
During the eight years of her tenure with LCC, she successfully managed RF design and optimization projects for AT&T Wireless, Southwestern Bell, Nextel, and other domestic and international clients. A Fellow with the Institute since 2000, she has developed and taught iDEN™ radio planning and optimization courses for the US and overseas clients. She led the development of the Institute's LMDS/MMDS curriculum. She has also developed the Institute’s RF radiation safety curriculum.
Her engineering experience and principal research interests include the TDMA systems (including GSM, iDEN™, and IS136), fixed wireless broadband, and RF radiation safety. Her work has also involved CDMA and experimental technologies.
Her interest in teaching goes way back to the days she taught Mathematics and Physics to high school students. During her employment with LCC, she developed, taught, and managed a set of workshops on frequency planning for various systems utilizing software/hardware tools. She has also edited and coauthored the LCC Optimization Processes document.
She has completed her undergraduate and graduate studies with master’s degree in Electrical Engineering at Moscow Telecommunications Institute and is a current member of IEEE.
