DOCSIS MAC Scheduler for WiFi Channel Bandwidth Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional WiFi networks face inefficiencies in managing wireless traffic due to the use of shared channels by multiple access points, leading to increased network congestion and reduced throughput, especially with the growing demand for multimedia applications that require higher data transmission and varied quality of service (QoS) across different devices and applications.
Innovation Solution
Implementing a DOCSIS MAC packet scheduler that optimizes channel bandwidth and resource allocation using channel quality estimation and scheduler algorithms like RED, WRED, and ARED to manage network congestion and ensure differentiated QoS, potentially replacing traditional WiFi schedulers and enhancing network performance by reducing packet loss and increasing channel efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple access points share wireless channels in conventional WiFi networks, then wireless coverage and device connectivity are improved, but network congestion increases and throughput decreases
Solution Approach 1:
The patent segments the wireless network into multiple independent WiFi access points, each operating on dedicated unlicensed spectrum channels. This segmentation prevents channel sharing conflicts between access points, allowing each to operate independently without causing network congestion, thereby maintaining high throughput while providing broad wireless coverage.
2Ease of operation
If traditional WiFi schedulers are used to manage wireless traffic, then basic network operation is maintained, but quality of service differentiation and network performance are insufficient
Solution Approach 1:
The patent introduces a DOCSIS MAC packet scheduler as an intermediary component within each WiFi access point. This scheduler applies cable industry-proven scheduling algorithms to WiFi traffic management, providing sophisticated quality of service differentiation, bandwidth control, and prioritization capabilities that traditional WiFi schedulers lack, while maintaining ease of operation through automated management.
3Quantity of substance
If channel bandwidth is increased to handle growing data traffic, then data transmission capacity is improved, but packet loss increases and network efficiency decreases
Solution Approach 1:
The patent implements dynamic bandwidth allocation and channel width selection in each WiFi access point, allowing the system to adaptively adjust transmission parameters based on real-time channel conditions and traffic demands. This dynamic approach optimizes data transmission capacity while maintaining packet integrity by selecting appropriate channel widths (20MHz, 40MHz, 80MHz) and modulation schemes to match current network conditions.

AI summary
Embodiments of the disclosure are generally directed to systems, methods, and apparatus for wireless packet scheduling using a data over cable service interface specification (DOCSIS) medium access control (MAC) scheduler. In some embodiments, the disclosed DOCSIS MAC scheduler can be partially or fully replace a traditional wireless scheduler, for example, a WiFi scheduler defined in connection with an institute of electrical and electronics engineers (IEEE) 802.11 standard. In some embodiments, a wireless network including such a DOCSIS MAC scheduler can have several improvements over conventional wireless networks, including, but not limited to, a reduction in lost packets due to collisions, a higher channel bandwidth performance by optimizing time-for-packet transmissions, and the addition of further network capabilities including, but not limited to, provisioned-bandwidth allocation to network devices using one or more scheduler algorithms.
