DALLAS, November 17, 2021 / PRNewswire / – COMSovereign Holding Corp. (NASDAQ: COMS and COMSP) (“COMSovereign” or the “Company”), a U.S. developer of 4G LTE Advanced and 5G communications systems and solutions, today announced that its Over-The-Air Testing (“OTA “) of its revolutionary Lextrum In-Band Full Duplex (IBFD) auto-interference cancellation technology. As a result of the completed tests, the company now introduces ASTARA ™ (Adaptive Simultaneous Transmit and Receive Antenna), an electronically reconfigurable stand-alone antenna technology specifically designed for self-interference cancellation applications. The new antenna system may allow some wireless network operators to quickly benefit from Lextrum’s IBFD technology with up to 100% increase in simultaneous bandwidth.

In-Band Full Duplex, the ability to simultaneously broadcast and receive wireless signals over a single wireless channel, has the potential to dramatically increase throughput and spectral efficiency in increasingly crowded spectrum bands and contested. Lextrum’s proprietary full-duplex in-band technology addresses the limitations of traditional time-division duplexing (TDD) methods by providing up to twice the throughput in any given channel and reducing the occupied bandwidth required for them. systems based on frequency division duplexing (FDD). Since it almost eliminates the need for additional guard band spacing, the overall reduction in bandwidth compared to traditional FDD can be more than a factor of 2.

Dr. Scott Velasquez, Director of Research at COMSovereign, said: ASTARA ™ is a breakthrough in spectral efficiency and is an essential enabling technology for practical IBFD communications operating on the most widely deployed frequencies, including the C and S bands which are crucial for emerging 5G deployments. Lextrum’s IBFD essentially doubles the data capacity of communications by using the same frequency band for simultaneous transmission and reception (STAR), and with the introduction of this new antenna technology, we are able to provide to the telecommunications industry a valuable new solution that addresses spectrum usage, one of the most significant challenges they face. “

ASTARA ™ strengths include:

  • ASTARA ™ is an electronically reconfigurable antenna that provides up to 70 dB of self-interference cancellation within the antenna itself. Efficient antenna calibration can be performed quickly and regularly, for example, during training intervals which are already provided for in the standards of modern communication systems to optimize the antenna cancellation performance in very demanding environments. variable or mobile
  • This new system exclusively available from Lextrum uses a reconfigurable array antenna to provide self-interference cancellation with bandwidth greater than 100 MHz to accommodate modern wideband and high-speed 5G waveforms.
  • Unlike traditional beamforming or beam steering approaches which require a large number of elements and complex adaptive control algorithms, the reception characteristics of ASTARA ™ can be electronically tuned to cancel its transmit signal without affect its beam, even in the presence of near-field reflections.
  • ASTARA ™ technology can be combined with other interference cancellation techniques, including digitally assisted analog cancellation, such as COMSovereign’s patented Adaptive Signal Cancellation (ASC ™) technology and fully digital signal separation techniques to provide total cancellation greater than 120 dB of self-interference cancellation.
  • Lextrum’s IBFD and antenna technologies will be available for licensing to radio manufacturers looking to upgrade their products to support bandwidth doubling through full duplex in-band operation.

“Confirmed by strong live test results, we believe Lextrum’s IBFD technology is an essential enabling technology for 5G where radio access network (RAN) densification will create significant challenges for network operators seeking to maximize the value of their billion – dollar investments in spectrum. This unique and valuable technology is a key differentiator in the market and that is why we are so excited that it is an integral part of our product roadmap for COMSovereign as we commercialize our next generation of 5G radios, including Polaris. G2 scheduled for introduction next year, ”added Dr. Dustin McIntire, CTO of COMSovereign.

A white paper titled “Full duplex in-band communications using a new adaptive reconfigurable antenna” Written by Scott R. Velazquez, Ph.D. and Dustin H. McIntire, Ph.D, detailing the live testing of Lextrum’s full duplex in-band and electronically reconfigurable ASTARA ™ antenna technology has been submitted for presentation at the GOMACTech 2022 conference scheduled for March 21st – 24, 2022. GOMATech was created primarily to examine developments in microcircuit applications for government systems. Established in 1968, the conference focused on advancements in systems developed by the Department of Defense and other government agencies and was used to announce major government initiatives in microelectronics.
