SENTEL Awarded Patent for Technology Enhancements to Battlefield Communications Systems

SENTEL Corp. has enhanced technology that will significantly improve communications capabilities by limiting frequency interference.

SENTEL Corp. has been granted a patent by the U.S. Patent and Trademark Office for a technology that is designed to enhance communications reliability in the “fog” of the battlefield by significantly limiting signal interference.

The technology is an improvement over an earlier innovation, developed and patented jointly by SENTEL and the Space and Naval Warfare Systems Command (SPAWAR). The previous patent enabled enhanced wireless communication in limited spaces by connecting one or more Radio Frequency (RF) receivers to a single antenna while reducing significantly the amount of interference that can occur when frequency-hopping radios are employed. This latest version employs cryogenics to improve filter performance, which allows the reception of more RF signals in less required spectrum.

Spectrum Dependent (SD) systems are often limited by co-located systems that can interfere with their operation and require additional frequency separation between circuits. This technology mitigates this issue without requiring the use of additional spectrum in “systems of systems” platforms. As a result, the spectrum is used more efficiently and results in the ability to crowd more RF circuits into a smaller spectrum.

“This patent truly places us in a strong position in terms of signals and the ability to deliver reliable communication capabilities to our customers,” said Darrell L. Crapps, SENTEL’s president and chief executive officer.
