BSS Color-Based EIRP Assignment for Wireless Network Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Assigning effective isotropic radiated power (EIRP) to access points in a wireless network is challenging when BSS colors and channel assignments are already given, as existing methods lack a centralized solution to optimize network performance, minimize disruptions, and ensure spatial reuse without affecting neighboring access points or roaming procedures.
Innovation Solution
A method and system that determine weights for neighboring access points based on channel frequency and BSS color, calculate path losses, and adjust EIRP values to achieve optimization goals, including spatial reuse, minimizing disruptions, and maintaining network performance by using a network device with a processor and memory to execute instructions for EIRP assignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If EIRP is assigned to access points with given BSS colors and channel assignments, then network performance optimization is achieved, but it becomes difficult to assign EIRP without affecting neighboring access points or roaming procedures
Solution Approach 1:
The patent assigns different EIRP values to access points based on their local BSS color and channel characteristics. Each access point's EIRP is optimized independently according to its specific neighborhood conditions, allowing network performance optimization while maintaining stability by not uniformly affecting all access points
Solution Approach 2:
The patent dynamically adjusts EIRP parameters based on BSS color and channel assignment parameters. By changing the EIRP parameter in response to specific BSS color and channel conditions, the system optimizes network performance while maintaining reliability through parameter-based adaptation rather than structural changes
2Productivity
If centralized EIRP assignment is implemented, then spatial reuse is optimized, but system complexity increases
Solution Approach 1:
The patent introduces a centralized controller as an intermediary that manages EIRP assignment based on BSS color and channel information. This intermediary coordinates between access points and optimizes spatial reuse while centralizing the complexity management, allowing individual access points to remain relatively simple while achieving system-wide optimization
3Reliability
If EIRP is adjusted based on neighboring access points, then disruptions are minimized, but calculation complexity increases
Solution Approach 1:
The patent performs preliminary calculations of path loss and determines appropriate EIRP values before actual transmission begins. By pre-calculating the optimal EIRP based on neighboring access point information and BSS colors, the system minimizes disruptions while managing calculation complexity through advance preparation rather than real-time computation

AI summary
Methods for assigning effective isotopic radiated power to an access point in a wireless network are provided. In one aspect, a method includes determining weights for neighboring access points in a wireless network based on channel frequency and basic service set color assignments. For a particular access point, a first path loss based on the determined weights and a second path loss based on the neighboring access points are calculated. First and second effective isotopic radiated power values are calculated based on the respective first and second path losses. The effective isotopic radiated power of the particular access point is adjusted based on the lower of the first and second calculated effective isotopic radiated power values. Systems and machine-readable media are also provided.
