Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Constant high-rate beaconing on multiple wireless data communication interfaces in information handling systems leads to increased power and processing bandwidth consumption, excessive spectrum congestion, and poor battery life in mobile applications, as well as interference issues in high user density environments.
Innovation Solution
Implementing a processor-controlled wireless data communication interface that selectively enables and disables beaconing and throttles beaconing frequency based on system states and events, using beacon rate state machines to manage power consumption and optimize wireless data communication links, thereby coordinating beaconing between interfaces and adjusting rates according to docked, undocked, stationary, or motion states.

Engineering Contradiction Analysis
1Reliability
If constant high-rate beaconing is implemented on multiple wireless interfaces, then wireless connection reliability is improved, but power consumption increases and battery life decreases
Solution Approach 1:
The patent implements dynamic beaconing rate adjustment where the beaconing frequency is continuously adapted based on current system state, motion detection, and connection quality metrics. The system transitions between different beaconing modes (high-rate when moving, low-rate when stationary) to optimize the balance between connection reliability and power consumption.
Solution Approach 2:
The system changes key parameters including beaconing rate, interface activation state, and transmission power based on detected conditions. When motion is detected or connection quality degrades, the system increases beaconing rate and activates additional interfaces; when stationary and connection is stable, it reduces beaconing rate to conserve power.
2Reliability
If high-rate beaconing is used to maintain wireless connections, then connection robustness is improved, but spectrum congestion increases causing interference
Solution Approach 1:
The patent applies different beaconing strategies to different wireless interfaces based on local conditions. Each interface is evaluated independently for its connection quality, motion state, and power consumption characteristics, allowing the system to optimize beaconing rate per interface rather than using a uniform approach across all interfaces.
Solution Approach 2:
The system uses partial beaconing by selectively enabling only the necessary number of wireless interfaces based on current needs. When one interface provides sufficient connection quality, other interfaces are disabled or placed in low-power mode, reducing overall spectrum congestion while maintaining adequate connection robustness.
3Reliability
If multiple wireless interfaces are activated for redundancy, then connection reliability is improved, but device complexity and power consumption increase
Solution Approach 1:
The patent combines the management of multiple wireless interfaces under a unified control system that monitors overall connection quality rather than treating each interface independently. The system merges beaconing control, power management, and interface selection into an integrated framework that simplifies decision-making and reduces operational complexity.
Solution Approach 2:
The control system performs multiple functions using a single integrated mechanism: it detects motion, evaluates connection quality, determines optimal beaconing rates, selects active interfaces, and manages power consumption. This multi-functional approach reduces the need for separate control circuits and simplifies the overall device architecture.

AI summary
A processor determines whether an information handling system is in a first state and directs a wireless data communication interface to provide a first connection beacon at a first rate based upon the information handling system being in the first state. The processor further determines whether the information handling system is in a second state and directs the first wireless data communication interface to provide the first connection beacon at a second rate based upon the information handling system being in the second state.
