ULTRALOGIC PATENTS FOR SUCCESSFUL WIRELESS DOMINATION


ULTRALOGIC patents enable extraordinary opportunities for faster, smarter, massively-parallel communications worldwide.  Soon everyone and everything can be connected.  We believe it can be done intelligently.

For example, ULTRALOGIC patents provide extremely resource-efficient procedures for antenna alignment, initial access, grant request and polling, and on-message demodulation.  To enable the promise of super-throughput MIMO communications in dense urban environments, our innovations push the boundaries on speed by enabling connectivity at the highest frequencies, where phase noise dominates most others.  And for even greater reliability, especially in mission-critical and life-or-death communications, ULTRALOGIC inventions show how to identify and rectify individual message faults in real-time as the message is received.

ULTRALOGIC breakthrough innovations enable smarter vehicles, smarter manufacturing, and smarter consumer products.  For example, we developed ways to precisely map traffic patterns in real-time for precision traffic control and collision avoidance.  ULTRALOGIC is a technology leader in applying Artificial Intelligence to solve communication roadblocks by reducing complex problems to fast, low-power solution algorithms - which even low-complexity devices can handle. 

We developed technology for adjusting modulation on-the-fly to avoid or minimize the current noise and interference, thereby opening the door to faster ultra-reliable communications.  As another example, we enable resource-efficient DRX polling by developing single-bit user-alert message protocols and cascaded signaling protocols.  As a third example, innumerable self-organizing local networks are the future of sidelink communications, and we developed ways to form, join, and localize such fluid networks at high resolution, using fast, low-complexity messaging.

Unlike expensive hardware technologies, our inventions are all software-based for easy, low-cost installation and upgrading.  ULTRALOGIC innovations do not replace 5G or 6G standards; we extend them - by providing fast, low-complexity connectivity to a wider range of users.  For example, ULTRALOGIC patents show how industrial sensors can avoid the tedious and time-consuming blind search to identify incoming messages, and instead to instantly recognize their messages even with a low-complexity processor.  Further innovations enable rapid, low-cost, low-power procedures to find and log on to the closest available base station, a valuable boon for future mobile users.

    Resource-Efficient Custom Downlink Search-Space in 5G/6G - July 27, 2022

    Receiving downlink messages is a huge energy waster because each user device needs to scan every possible time/frequency/size combination continuously. This is solved by assigning a particular time and frequency resource to each user, such that every downlink message to that user must start in the assigned space.
    Result: GREATLY REDUCED COMPUTATIONAL DEMANDS.

    Artificial Intelligence Fault Localization in 5G and 6G Messages - June 28, 2022

    This patent uses artificial intelligence and machine learning to determine which specific message elements, of a corrupted message, are faulted. The receiver can then attempt to mitigate those faulted message elements, or request a retransmission of the faulted portion of the message.
    Result: HIGHER RELIABILITY WITHOUT RE-TRANSMISSIONS.

  • US 17,848,828
    Selection of Faulted Message Elements by Modulation Quality in 5G/6G - June 24, 2022

    Message faults result in delays and additional background due to retransmission requirements. In this patent, the specific faulted message elements are identified by measuring the modulation quality. The receiver may then attempt to recover the message without requesting a retransmission.
    Result: LOWER LATENCY.

  • US 17,846,100
    Demarking the Start and End of 5G/6G Downlink Messages - June 22, 2022

    Placing a distinctive bit pattern at the start and end of each message helps the receiver identify messages in the stream of data, and to pick out the messages intended for it. A different bit pattern is used at the start and the end.
    Result: REDUCED COMPUTATION REQUIREMENTS.

  • US 17,842,901
    Modulation Quality and Fault Mitigation in 5G/6G - June 17, 2022

    To detect individual faulted message elements, the receiver can measure how far the amplitude and phase deviate from the calibrated modulation levels. Large deviations indicate a faulted message element, leading to recovery of the corrected message.
    Result: REDUCING RE-TRANSMISSION BURDENS.

  • US 17,841,235
    Geographical Localization of 5G/6G Network Users and Base Stations - June 15, 2022

    Disclosed are rapid, efficient ways for users and base stations to set up directed "beams" toward each other, thereby obtaining greatly increased reception quality at a fraction of the transmitted power.
    Result: SAVING WASTED POWER.

  • US 17,841,061
    Demodulation Reference for High Background Rejection in 5G or 6G - June 15, 2022

    In a busy wireless environment, the interference can change quickly. Disclosed are compact, single-element demodulation references that can be embedded within a message at numerous places, to provide a real-time mitigation of current interference and noise.
    Result: FEWER MESSAGE FAULTS.

    Polarization Encoding for High-Density 5G/6G Communication - April 25, 2022

    Wireless waves are usually polarized in the vertical direction. In this patent, the other polarization state, horizontal, is also employed for carrying data. Expanded modulation tables are disclosed exploiting the extra degree of freedom.
    Result: HIGHER INFORMATION DENSITY WITH NO INCREASE IN BANDWIDTH.

  • US 17,685,655
    Short-Form 5G/6G Pulse-Amplitude Demodulation References - March 3, 2022

    In pulse-amplitude modulation, a message can be demodulated by amplitude measurements alone. This patent discloses extremely compact demodulation references, which assist the receiver in demodulating the message correctly despite noise and interference.
    Result: FEWER DROPPED MESSAGES, SHORTER TRANSMISSIONS.
