Press Releases

DALLAS, Feb. 15, 2022 /PRNewswire/ -- COMSovereign Holding Corp. (NASDAQ: COMS and COMSP) ("COMSovereign" or the "Company"), a U.S.-based developer of 4G LTE Advanced and 5G communication systems and solutions today announced that its Chief Research Officer, Dr. Scott Velazquez has been selected to present three technology whitepapers at the upcoming GOMACTech 2022 conference scheduled for March 21 - 24, 2022. Established in 1968, the GOMACTech conference has focused on advances in systems being developed by the Department of Defense ("DoD") and other government agencies and has been used to announce major government microelectronics initiatives.

During the conference, Dr. Velazquez will present three whitepapers discussing advanced, patented wireless communications and optical networking solutions developed by COMSovereign including: Lextrum's ASTARA™ In-Band Full Duplex ("IBFD") antenna technology; Innovation Digital's application of TM Technologies' Transpositional Modulation for spectral efficiency; and VEO's enabling modulator and photodetector designs for high-performance ultra-wideband photonic links. Collectively, these critical enabling technologies address radio spectrum efficiencies required for 5G communications and forthcoming optical/photonic data computing and networking.

Dr. Scott Velazquez, Chief Research Officer at COMSovereign, said, "The opportunity to present three of COMSovereign's groundbreaking technologies at GOMACTech, directly to key decision makers and some of the foremost experts in advanced communications technology in the DoD is exciting and serves as a platform for us to validate the potential value inherent in our IP portfolio."

Details of the presentations include:

• VEO - Novel Modulator and Photodetector for High Speed/High Performance Analog/Digital Photonic Links
  VEO's patented silicon-rich-nitride (SRN) modulator and patent pending slab-assisted silicon germanium (SiGe) photodetector are two novel components enabling next generation performance for optical communications networks. Leveraging its stronger electro-optical effect, VEO's SRN modulator is expected to deliver a 10X improvement in transmission speed, energy efficiency, and loss compared to today's state-of-art silicon modulators. VEO's SiGe photodetector uses a novel slab-assisted coupling structure to enhance power handling, receiving speed, and efficiency, enabling higher speed and higher signal-to-noise photonic links, significantly enhancing optical networking applications such as 5G+ networks, data centers, and remote antenna solutions.
  
  
• Innovation Digital / TM Technologies - Transpositional Modulation (TM) for Spectrum Efficiency and Obfuscated Communications
  Transpositional Modulation (TM) is a patented radio frequency waveform technology that offers dramatic bandwidth increases for existing wireless and wired networks. TM accomplishes this by enabling the simultaneous transmission of two or more distinct data paths on a single carrier signal. This effectively allows for increases in the efficiency of the carrier waveform by up to 50% or more. Proprietary and patented digital pre-distortion (DPD) linearization techniques by Innovation Digital are used to reduce distortion in the transceiver hardware to allow the addition of transparent TM signals without exceeding regulatory emissions requirements. In effect, TM can coexist simultaneously in a signal transmission with the existing modulation technologies allowing the transmission of more data for a given bandwidth. In addition, obfuscated communications are made possible since the additional TM signals are indistinguishable from typical noise and distortion.
  
  Transpositional Modulation is a proprietary technology developed and owned by TM Technologies, Inc. and is being combined with Innovation Digital's (a COMSovereign company) DPD technology under a cross-licensing agreement using next generation RF solutions for development of a new line of advanced telecommunications radios.
  
  
• Lextrum ASTARA™ - In-Band Full-Duplex Communications Using a Novel Adaptive Reconfigurable Antenna
  ASTARA™ (Adaptive Simultaneous Transmit and Receive Antenna), is a standalone, electronically reconfigurable antenna technology specifically designed for self-interference cancellation applications. The new antenna system can enable some wireless network operators to quickly benefit from Lextrum's IBFD technology with up to a 100% increase in simultaneous bandwidth without replacing any radio hardware already in use. Lextrum's IBFD technology essentially doubles the data capacity of communications by using the same frequency band for simultaneous transmission and reception (STAR), providing the telecommunications industry with a valuable new solution that addresses efficient spectrum usage, one of the most significant challenges faced in 5G wireless networking."
