In an effort to maximize utilization of the available spectrum to address the explosive growth of wireless data traffic, Lextrum, Inc. has reached another development milestone, completing the hardware and firmware integration of its in-band full duplex passive suppression and active cancellation technology. Based upon initial testing, Lextrum has verified that its proprietary in-band full duplex hardware and firmware technology can mitigate an aggregate 120 dB of self-interference resulting in 100 percent throughput improvement over current Time Division Duplex-based systems like those utilized in 3G and Wi-Fi networks. 

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 time and/or and frequency division duplexing methods by delivering up to a 100 percent throughput improvement over temporal based systems. Lextrum will complete its in-band full duplex technology integration with a 3GPP Release 15 LTE Software Defined Radio (SDR) by year-end. The company expects to begin over-the-air interoperability testing of its in-band full duplex enabled 4G LTE-A proof-of-concept SDR using its FCC granted experimental license starting next quarter.

“Whether it is in a cellular network or Wi-Fi, there can be no doubt that the numbers of networked devices are exponentially growing. To support potentially millions of new connections, we need to overcome the inherent capacity limitations of wireless spectrum and that is why we believe in-band full duplex technology has the potential to unlock the power of wireless networks today and in the future,” said Bob Hopkins, CEO of Lextrum.
