About Saraband Wireless

Incorporated in 2000 in the Commonwealth of Virginia, Saraband Wireless is a privately held company whose main purpose is the development of propagation analysis circuits and systems for enhancing performance of broadband wireless in licensed and unlicensed bands.  Our founders are pioneers in digital signal processing, forward error correction coding, and modulation.  

Our company history

Saraband is the recipient of National Science Foundation grants and shareholder funding.  Development of intellectual property (IP) in the form of patents, company secrets, and practical experience building and testing hardware can be time-consuming and expensive; we know because we started out by following this path.  One of our survival techniques is our willingness to wait out lengthy patent deliberations while chipping away at larger and larger swaths of IP relating to core requirements of advanced high speed broadband systems.  Our intellectual property portfolio now contains gatekeeper patents and patents pending on multiple input multiple output (MIMO) technology, diversity combining, mobile wireless, satellite-based unwanted emitter location systems, and high bits per Hz orthogonal frequency division multiplexed (OFDM) modulation. 

Our people

Donald S. Arnstein                President

Dr. Arnstein's specialty is the performance of tradeoffs, system design and analysis for efficient, robust, interoperable, secure, high bits per Hz communications. He is an expert on satellite communications, on anti-jam & low probability of intercept communications, and on the use of channel sounding techniques for non-line-of-sight wireless communications. He is the author of many peer reviewed papers and conference presentations and is an inventor on U.S. patents and patents pending. He designed the authentication and encryption mechanisms for the Thuraya satellite and the Spaceway Project. Dr. Arnstein is a Senior Member of the IEEE, past Secretary of the Washington D.C. chapter of the Communications Society, and has served as an Associate Professorial Lecturer at the School of Engineering and Applied Sciences at George Washington University.  He has an Sc.D. degree from UCLA, and was a Lincoln Laboratory Staff Associate.

Paul M. Ebert                        Vice President

Dr. Ebert is a Life Senior Member of the IEEE and a nominee for Fellow Grade.  He received an Sc. D. from MIT, and has worked at Bell Labs, MITRE, and Comsat.  Dr. Ebert has extensive experience in the theoretical aspects of communications, such as OFDM, digital filters, software defined modems, and channels with feedback,  as well as actual implementation.  He designed what is now the international standard airborne collision avoidance system called TCAS.  He is a founder of Saraband Wireless and co-inventor of embedded propagation measurements.  He has recently performed on-site consulting for Comtech's Mobile Datacom Division.  At Mobile Datacom, he designed an all digital satellite packet communication and location system for hand held transceivers.  At Adsystech in Maryland, he did performance analysis for the FAA on airborne GPS receivers.  At Comsat corporation in Clarksburg MD, he led the team that designed and built new all-digital transmission Inmarsat earth stations. At MITRE Corp., he invented and built the first prototype of the aircraft collision avoidance system, now required in all large commercial aircraft.  He was on the team at Bell Labs that invented the current OFDM modulation and demodulation scheme used in wireless communications.  Paul's Bell Labs paper on OFDM recently appeared in an anthology compiled by IEEE Communications Society called The Best of the Best (2007).

Kim Tran                              CFO

Ms. Tran is a founder of Saraband Wireless and its Chief Financial Officer. She has an extensive background in finance and administration with Fortune 500 companies as well as start-up companies in the Washington D.C. area. She has specialized in financial planning, analysis, and treasury. Her experience includes line of credit arrangements, straight and convertible debt and equity issuance, and investor relations. She received an MBA in Finance and Marketing from Columbia University in New York City.

Kiet Truong                          Implementation Consultant

Mr. Truong is a founding partner of Saraband Wireless. He helped develop commercialization plans for Saraband Wireless' channel measurement equipment, and he has more than 25 years of experience developing electronic designs. He has extensive experiences in satellite and wireless communication systems, DSP-based software radio receiver designs, SONET/SDH optical networking, ATM networking and packet switching, router/switch architectures. As a hardware design engineer working at Cisco systems, Mr. Truong was responsible for supporting the integration and test team of the Cisco’s ONS-15454 and ONS-15327 Optical SONET/SDH Add/Drop Mux products. The product combined transport and multiplexing functionalities and is deployed in MAN fiber optic ring networks.  While at COMSAT Laboratories he was responsible for development of several ATM-over-Satellite products. He also gained proficiency with Cadence Concept design tools, schematic capture, simulation and Altera Maxplus CPLD/FPGA design tools. Prior to this, Mr. Truong was at COMSAT RSI where he worked with DSP software for Inmarsat satellite modems, for land earth station and satellite network control center equipment such as Inmarsat Mini-M SCPC Modem, which supports SCPC voice, fax, and data modes, Inmarsat Mini-M TDM and TDMA modem. He also worked on the Inmarsat Standard A TDM and TDMA modem, the Inmarsat Standard B SCPC modem, Inmarsat Standard C TDM and TDMA modem, and Inmarsat Standard M SCPC modem.
