Frequency Band Allocation for Wireless Access Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In indoor environments with multiple Access Points (APs) for next-generation wireless Local Area Networks, existing technologies face challenges in efficiently assigning frequency bands, leading to wasted frequency resources and reduced channel availability due to varying traffic volumes and service types.
Innovation Solution
A frequency band setting apparatus and method that calculates basic frequency bands for each AP and divides available frequency bands into both basic and common frequency bands, allowing APs to share a common frequency band, which can be contiguous or non-contiguous, to optimize frequency usage and assign bandwidths based on demand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a significant amount of bandwidth is assigned to every AP to handle various traffic types, then each AP can provide adequate service capacity, but frequency resources are wasted and the number of simultaneously assignable channels is reduced
Solution Approach 1:
The patent segments the frequency band into two distinct types: basic frequency bands allocated to individual APs based on their calculated requirements, and common frequency bands that can be shared by multiple APs. This segmentation allows the system to guarantee minimum service capacity to each AP while enabling efficient resource sharing, thereby resolving the contradiction between service capacity and frequency resource utilization.
Solution Approach 2:
The common frequency band serves multiple functions: it can be allocated to different APs depending on real-time traffic demands, and multiple APs can simultaneously utilize this shared band. This multi-functionality allows the system to provide adequate service capacity to multiple APs without requiring dedicated frequency resources for each, thus improving overall frequency resource efficiency.
2Adaptability or versatility
If different channels of wide bands are assigned to multiple APs to support various service types, then each AP can operate independently, but the number of simultaneously assignable channels is reduced
Solution Approach 1:
The patent introduces dynamic frequency band allocation where APs can flexibly switch between using their dedicated basic frequency bands and sharing common frequency bands based on real-time traffic conditions. This dynamic approach allows the system to maximize the number of simultaneously assignable channels by efficiently utilizing shared resources, thereby resolving the contradiction between channel availability and productivity.
3Quantity of substance
If frequency bands are divided into basic and common bands to maximize frequency usage, then resource efficiency is improved, but the complexity of frequency band management increases
Solution Approach 1:
The patent implements a self-service mechanism where each AP calculates its own basic frequency band requirements based on its traffic characteristics, and the system automatically allocates frequency bands without requiring complex manual configuration. This automated self-service approach simplifies frequency band management while maintaining high resource efficiency, as the system dynamically adjusts allocations based on actual needs.
