Patent number: 11696155Abstract: Presented are Ergodic Spectrum Management (ESM) systems and methods that take advantage of the presence of statistical consistencies (“ergodicity”) and correlations, such as a wireless network's average dimensional consistencies of probability distributions (in time, space, and frequency) of channel gains, to adaptively learn qualitative and quantitative network/user behavior; estimate or predict network performance; and guide locally implemented radio resource management (RRM) decisions of wireless multi-user transmissions in a manner such as to reduce interference and improve latency; connection stability; efficiency; and overall wireless performance. ESM also enhances end-users' Quality of Experience (QoE) by allowing movement across bands and regions as users/devices roam. A remote-cloud-based resource management implementation of ESM's Learn-ed Resource Managers (LRMs) removes the need for heavy edge-computing close to radio cells.Type: GrantFiled: February 27, 2020Date of Patent: July 4, 2023Assignee: ASSIA SPE, LLCInventors: John M.

Publication number: 20230188311Abstract: Embodiments of the present invention provide systems, devices and methods for improving the performance and range of wireless communication systems. In various embodiments, a wireless and wireline architecture is implemented to allow a channel to more efficiently span physical barriers within the channel. The wireline portion of the channel may leverage pre-existing copper deployed within a building by interfacing copper with north and south transceiver nodes that allow the signal to propagate through a physical structure on the wire itself resulting in significantly less signal degradation compared to the signal having to traverse the physical structure wirelessly.Type: ApplicationFiled: February 14, 2023Publication date: June 15, 2023Applicant: ASSIA SPE, LLCInventors: John M.
