Wireless Power Adjustment for Consistent Channel Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless networks face challenges in maintaining consistent wireless coverage and preventing disconnects when switching between wireless channels, as the power levels of different channels are not uniformly managed, leading to reduced cell coverage and potential disconnections for edge-of-cell stations.
Innovation Solution
A communication management resource determines and applies wireless power level control settings to ensure that each wireless channel of a wireless station operates at a substantially equal power output level, thereby maintaining consistent wireless coverage and minimizing disconnects during channel switches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If different preset wireless output power levels are used for each wireless channel, then channel interference is reduced, but cell coverage is reduced and disconnects occur for edge-of-cell stations
Solution Approach 1:
The patent changes the power level parameter dynamically based on the selected wireless channel. Instead of using fixed different power levels for different channels, the system adjusts the power level to compensate for channel-specific characteristics, ensuring consistent effective coverage while reducing interference on specific channels.
Solution Approach 2:
The patent introduces dynamic power level adjustment based on channel selection. The power level is not static but changes according to which channel is being used, allowing the system to optimize both interference reduction and coverage maintenance through real-time adaptation.
2Adaptability or versatility
If a new wireless channel is selected to replace an original channel, then channel optimization is achieved, but wireless coverage is reduced due to lower power level on the new channel
Solution Approach 1:
When switching channels, the patent adjusts the power level parameter to compensate for the new channel's characteristics. This ensures that the effective coverage area is maintained despite changing channels, by modifying the transmit power to account for channel-specific propagation characteristics.
Solution Approach 2:
The patent performs preliminary power level adjustment before or during channel switching to ensure coverage continuity. By proactively setting the appropriate power level for the target channel, the system prevents coverage reduction that would otherwise occur during channel transitions.
3Reliability
If maximum power levels are transmitted to ensure quality of service, then communication quality is improved, but energy consumption increases and interference to other channels increases
Solution Approach 1:
The patent dynamically changes the power level parameter based on channel conditions and selection rather than always transmitting at maximum power. This allows the system to maintain communication quality when needed while reducing energy consumption and interference during normal operation by adjusting power levels to appropriate values for each channel.

AI summary
Processing hardware receives first power level control information to control operation of a wireless station. The first power level control information includes first control settings to control wireless power output levels of the wireless station for multiple wireless channels. Implementation of the first control settings at the wireless station resulting in different wireless power output levels. The processing hardware produces second power level control information as a replacement to the first power level control information. The second power level control information includes second control settings. Application of the second control settings is operative to substantially equalize wireless power output levels of the wireless station over each of the multiple wireless channels.
