SSID-Based Bandwidth Allocation for Wireless Network QoS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless networks face limitations in area coverage and performance due to the division of bandwidth among multiple access points, leading to unsatisfactory service quality as the network expands, as more access points necessitate further division of already limited bandwidth.
Innovation Solution
Implementing a wireless network architecture where each user is assigned a unique Service Set-Identifier (SSID) to manage and allocate bandwidth based on service type, allowing for differentiated Quality of Service (QoS) parameters and prioritization, enabling efficient bandwidth distribution among various users and services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If more wireless access points are deployed to expand network coverage, then the area coverage is improved, but the bandwidth is divided further leading to deteriorated service quality
Solution Approach 1:
The patent segments the wireless network into multiple independent SSID-based virtual networks, each with dedicated bandwidth allocation. Instead of sharing a single pooled bandwidth across all users, the system divides the network into separate service domains (e.g., premium users, standard users, backhaul connections) where each segment receives guaranteed bandwidth resources, preventing the bandwidth division problem that occurs with traditional access point expansion.
2Adaptability or versatility
If bandwidth is divided among more access points to support network expansion, then the network can span further areas, but the bandwidth allocation becomes insufficient leading to deteriorated performance
Solution Approach 1:
The patent implements dynamic bandwidth allocation through SSID-based QoS policies that can be adjusted in real-time based on network conditions and service requirements. The system dynamically assigns bandwidth thresholds and priorities to different SSIDs, allowing the network to adapt to changing traffic patterns and user demands without requiring physical access point additions, thereby maintaining bandwidth efficiency while supporting network expansion.
3Area of stationary object
If traditional wireless network expansion is implemented by adding more access points, then coverage area increases, but the complexity of bandwidth management increases leading to untenable network architecture
Solution Approach 1:
The patent introduces SSID-based QoS policies as an intermediary layer between the physical network infrastructure and the bandwidth allocation mechanism. This intermediary abstracts the complex bandwidth management tasks into simple policy-based rules that can be configured and enforced centrally, eliminating the need for complex per-access-point bandwidth negotiations and simplifying the overall network architecture while supporting extensive coverage areas.

AI summary
Embodiments provide a wireless network with several access points connected to a communication infrastructure. Residential or business customers of the Internet are provided an Internet interface (e.g., a digital subscriber line (DSL) modem) having a wireless transceiver. Two or more users may access the Internet or other network through the Internet interface. Each user can be assigned a unique Service Set-Identifier (SSID) with each SSID associated with a type of service (e.g., user video service, backhaul service, etc.). The amount of bandwidth assigned to the type of service (and user) may be governed by the equipment according to the assigned SSID.
