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.

Wireless users are required to state the size of their message before being allowed to transmit it, resulting in extra delays.

Result: FEWER STEPS, TIME SAVED.
Custom Downlink Search-Spaces for Low-Complexity 5G/6G Messaging - September 6, 2022
Downlink messages are difficult to receive in 5G/6G. Users are expected to "blind-search" a huge range of possible time-frequency spaces to find a message among clutter.

Wireless Message Collision Avoidance with High Throughput - October 27, 2020
Wireless transmissions often need to be delayed, to avoid conflicts. Unfortunately, in 5G, each successive delay is required to be longer than the last, which unfairly penalizes the delayed user. In this patent, the base station moves the most-delayed user to the head of the line for the next available transmission opportunity.
Result: SHORTER DELAYS, FEWER DROPPED MESSAGES.
Wireless Protocols for Emergency Message Transmission - October 27, 2020
