COMSovereign Holding Corp. announced that its completed Over-The-Air testing of its breakthrough Lextrum In-Band Full Duplex (IBFD) self-interference cancellation technology. As a result of the completed testing, the Company is now introducing ASTARA? (Adaptive Simultaneous Transmit and Receive Antenna), 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. 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 congested and contested spectrum bands. Lextrum's proprietary in-band full duplex technology addresses the limitation of traditional Time Division Duplexing (TDD) methods by delivering up to twice the throughput in a given channel and reduces the occupied bandwidth required for Frequency Division Duplexing (FDD) based systems. As it nearly eliminates the need for additional guard band spacing, the overall reduction in bandwidth as compared to traditional FDD can be greater than a factor of 2. ASTARA? highlights 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 provisioned in modern communications systems standards to optimize the antenna's cancellation performance in highly variable or mobile environments This novel system exclusively available from Lextrum uses a reconfigurable array-based antenna to provide self-interference cancellation with a bandwidth that exceeds 100 MHz to accommodate modern wideband, high data rate 5G waveforms. Unlike traditional beamforming or beam steering approaches which require large numbers of elements and complex adaptive control algorithms, ASTARA?'s reception characteristics can be electronically tuned to cancel its transmit signal without affecting its beam pattern, even in the presence of nearfield reflections. The ASTARA? technology can be combined with other interference cancellation techniques including digitally assisted analog cancellation such COMSovereign'spatented 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 via in-band full duplex operation.
