Prior art

To identify the most relevant prior art for US patent 12015933, I will examine the "Citations" section of the patent document. Since the task asks for an analysis of the citations for 12015933, I will focus on the documents listed as prior art by the examiner or third parties.

Here are the most relevant prior art citations for US patent 12015933:

1. US5073899A

• Full Citation: US5073899A - Transmission system for sending two signals simultaneously on the same communications channel
• Publication Date: 1991-12-17
• Filing Date: 1988-07-13
• Brief Description: This patent describes a transmission system capable of sending two signals simultaneously over the same communications channel.
• Potentially Anticipates Claim(s) under 35 U.S.C. § 102: This patent could potentially anticipate aspects of claim 25 related to simultaneous transmission and reception, or the simultaneous use of multiple signals, if interpreted broadly, especially if the "two signals simultaneously on the same communications channel" could be considered analogous to a bandwidth allocation for different data streams. However, without more specific details on how the signals are managed and if they involve separate transceivers and virtual layers as defined in US12015933, direct anticipation is difficult to confirm.

2. US5818830A

• Full Citation: US5818830A - Method and apparatus for increasing the effective bandwidth of a digital wireless network
• Publication Date: 1998-10-06
• Filing Date: 1995-12-29
• Brief Description: This patent details a method and apparatus for increasing the effective bandwidth of a digital wireless network.
• Potentially Anticipates Claim(s) under 35 U.S.C. § 102: This patent likely anticipates aspects related to improving bandwidth performance in wireless networks. Specifically, claims 1 and its dependent claims, which discuss allocating portions of bandwidth from multiple transceivers to satisfy application bandwidth requirements, could be anticipated. The abstract of US12015933 focuses on allocating bandwidth to virtual MAC and PHY layers to satisfy bandwidth requirements, which aligns with the goal of increasing effective bandwidth.

3. US20020152305A1

6. US20050195821A1

• Full Citation: US20050195821A1 - Method and apparatus for dynamically controlling traffic in wireless station
• Publication Date: 2005-09-08
• Filing Date: 2004-03-03
• Brief Description: This patent describes a method and apparatus for dynamically controlling traffic in a wireless station.
• Potentially Anticipates Claim(s) under 35 U.S.C. § 102: This prior art is highly relevant to the "processing layer evaluates the wireless bandwidth requirement" and the allocation of bandwidth to satisfy application requirements as defined in claim 1. Dynamic traffic control often involves managing and allocating available resources, which is central to US12015933.

7. US20060114851A1

• Full Citation: US20060114851A1 - Method and apparatus for multi-channel MAC protocol using multi-tone synchronous collision resolution
• Publication Date: 2006-06-01
• Filing Date: 2004-11-30
• Brief Description: This patent describes a method and apparatus for a multi-channel MAC protocol using multi-tone synchronous collision resolution.
• Potentially Anticipates Claim(s) under 35 U.S.C. § 102: The "multi-channel MAC protocol" could anticipate aspects of a virtual MAC layer managing multiple PHY resources, particularly if the virtual MAC in US12015933 is seen as managing different channels or frequencies. Claim 1, which refers to allocating bandwidth to virtual MAC and PHY layers, could be impacted.

8. US20060140123A1

• Full Citation: US20060140123A1 - Methods and apparatus for distributing link-state information associated with a wireless mesh network

• Brief Description: This patent describes methods and apparatus for distributing link-state information in a wireless mesh network.
• Potentially Anticipates Claim(s) under 35 U.S.C. § 102: This could potentially anticipate the monitoring function of the ultra-streaming block that "feeds back wireless resource availability to the decision block" as described in the specification of US12015933 (related to FIG. 1 and FIG. 8). Understanding link-state information is analogous to knowing resource availability.

9. US20070110198A1
