SIMULTANEOUS, SINGLE-CHANNEL TRANSMIT AND RECEIVE TECHNOLOGY DOUBLES THROUGHPUT AND MAXIMIZES SPECTRAL EFFICIENCY ESSENTIAL TO 5G

WHY THIS IS IMPORTANT

CURRENT TECHNOLOGIES HAVE PERFORMANCE LIMITATIONS

Time Division Duplex (TDD) technology uses a single channel alternating between downlink (DL) or uplink (UL) which limits capacity/throughput. Frequency Division Duplex (FDD) uses two independent channels for DL and UL but requires twice the spectrum. Neither TDD nor FDD can simultaneously transmit and receive on a single channel - a limitation that network advancements and 5G will expose.

LEXTRUM'S FULL DUPLEX TECHNOLOGIES SIMULTANEOUSLY TRANSMIT AND RECEIVE ON A SINGLE CHANNEL

Our technology resolves the limitation of current TDD and FDD by increasing network performance and doubling spectrum efficiency.

THE CONNECTED WORLD NEEDS MORE EFFICIENT SPECTRUM

About Lextrum

ABOUT US

OUR DEVELOPMENT

We were founded in 2015 at University of California, Irvine by a team of network technology specialists in the field of RF transmission. We emerged from UCI's Applied Technology incubator in 2019 after our development of patented FD transceiver intellectual property that can be easily integrated into current systems. Our use of beam steering antennas controlled by smart antenna heuristics to achieve spatial filtering of self-interference multipath is our core technology. Cancelling the major self-interference multipath energy components in the propagation domain reduces the compression of the front-end, improves linearity and increases the bandwidth that can be handled by the system by inherently reducing frequency selectivity.

In 2019, we were acquired by COMSovereign Corporation (Stock Symbol : COMS) to combine our technologies with COMSoverign communication-focused subsidiaries' products and service to support the upgrade of "Transitional" 4G LTE networks for a nationwide upgrade to the 5G platform.

RESOLVE CURRENT NETWORK TRANSMISSION LIMITATIONS

THE CHALLENGE FOR SPECTRAL EFFICIENCY

AND HOW LEXTRUM SOLVES IT

TDD AND FDD LIMITATIONS

THE LEXTRUM FD SOLUTION

FDD, and later TDD, technologies have been the foundation of 2G, 3G, and most recently 4G networks. With the advent of 5G networks, and the continually growing need for both spectrum efficiency and increased throughput, these traditional technologies have reached their limits.

The Lextrum FD solution marries the spectral efficiency of TDD with the throughput advantage of FDD, making it the obvious choice for meeting the rigorous requirements of today’s developing 5G networks. The flexibility of the Lextrum FD solution means it can support legacy 4G protocols, and new 5G protocols, allowing a seamless transition from one generation to another, as networks evolve.
