Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User devices often face challenges in connecting to Wi-Fi networks due to asymmetric received signal strength indicator (RSSI) issues and beacon transmission at the lowest configured rate, leading to unsuccessful connections despite detecting the network presence.
Innovation Solution
Dynamically configuring beacon transmission rates and transmit power to match the capabilities of user devices, allowing for selective association based on supported modulation and data transfer rates, and evaluating connectivity quality through RSSI and noise floor analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the AP transmits beacon at the lowest configured rate, then all user devices can potentially discover the network, but user devices with limited capabilities cannot successfully connect and sustain quality connections
Solution Approach 1:
The patent applies dynamics by making the beacon transmission rate adjustable rather than fixed at the lowest configured rate. The system dynamically selects beacon rates based on the capabilities of user devices, allowing the network to adapt its transmission parameters to match device capabilities while ensuring successful connections.
Solution Approach 2:
The patent changes the transmission parameter (beacon rate) from a static lowest rate to a dynamic parameter that can be adjusted according to user device capabilities. This allows the system to optimize both network discoverability and connection success rate by matching beacon rates to device support levels.
2Illumination intensity
If the AP has more powerful transmit power than the user device, then the user device can receive and process the signal from the AP, but the AP cannot receive and process the signal from the user device (asymmetric RSSI problem)
Solution Approach 1:
The patent applies dynamics by making the AP's transmit power adjustable based on user device capabilities. Instead of using fixed high power, the system dynamically adapts the transmit power level to match the receiving capability of the user device, ensuring bidirectional communication reliability while avoiding the asymmetric RSSI problem.
Solution Approach 2:
The patent changes the transmit power parameter from a fixed high level to a dynamic parameter that can be adjusted according to user device receiving capabilities. This allows the system to optimize signal strength for downlink while preventing uplink reception failures by matching power levels to device capabilities.
3Area of stationary object
If the beacon is sent at the lowest configured rate, then maximum coverage area is achieved, but connection quality and data transfer performance are compromised
Solution Approach 1:
The patent applies dynamics by making the beacon transmission rate adjustable based on user device capabilities and connection requirements. The system dynamically selects appropriate beacon rates to balance coverage area and data transfer performance, rather than being constrained to the lowest rate for maximum coverage.
Solution Approach 2:
The patent changes the beacon rate parameter from a fixed lowest rate to a dynamic parameter that can be adjusted according to device capabilities and performance requirements. This allows optimization of both coverage area and data transfer rate by selecting appropriate rates for different scenarios.

AI summary
Systems and methods for managing a network are disclosed. One method can comprise determining a first modulation rate associated with a network device. A beacon can be transmitted at a second modulation rate, wherein the second modulation rate is greater than the first modulation rate. A user device can be associated with the network device based on the beacon if the user device is configured to support the second modulation rate.
