Purpose
The disclosure relates to wireless networks, specifically high-bandwidth wireless networks for distributing multi-media content. It addresses the problem that a given hotspot or wireless access point typically has a limited range and coverage area.
Plain-language scope
The system employs multiple wireless access points (nodes) that extend coverage linearly (serial or wirelessly daisy-chained) or radially. In the linear example, node 102A's radio A1 receives/transmits to a network such as the Internet and also serves users in its area; a relay radio A2 communicates with radio B1 of node 102B. Node 102B may use three radios: one to communicate with A2, a relay radio B2 to node 102C, and a third radio B3 as an access point for user U2. Thus a user U3 can access the Internet even though the distance to A1 exceeds A1's range. Nodes may be configured differently based on resources and bandwidth demands—a radio may handle multiple tasks if bandwidth demand is low, or a single task if more transceiver resources are needed. Embodiments include a wireless management system using a virtual MAC and virtual PHY to adaptively manage multiple radios, and cooperating management systems that allocate transceiver resources between users. Claim 1 recites a first access point with first and second transceivers, and a second access point with third and fourth transceivers providing user access via the wireless link.

All PTAB activity →AIA trial proceedings (IPR / PGR / CBM) filed at the USPTO Patent Trial and Appeal Board against this patent. Sourced from the USPTO Open Data Portal and refreshed every six hours; each proceeding number deep-links to the PTAB E2E docket.
No PTAB proceedings on file. This patent has not been challenged via IPR, PGR, or CBM. The absence is itself a signal — well-asserted patents eventually attract IPRs. The LLM analysis below may surface filings the ODP feed hasn’t indexed yet.
PTAB challenges
AIA trial proceedings at the USPTO Patent Trial and Appeal Board — IPR, PGR, and CBM. Petitioners, judge panels, claim-level invalidation outcomes from Final Written Decisions, and Federal Circuit appeals. The single most important defensive datapoint after litigation history.
Assignment history
Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.
Prior art
Earlier patents, publications, and products that may anticipate or render the claims unpatentable.
Obviousness
Combinations of prior art that suggest the claimed invention would have been obvious under 35 U.S.C. § 103.
Extensions
Patent term adjustments, term extensions, continuations, divisionals, family members, and expiration dates.
Derivative works
Defensive disclosure: derivative variations of each claim designed to render future incremental improvements obvious or non-novel.
