Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network throughput in sub-7.25 GHz and millimeter wave links is limited by high penetration loss and scattering in the 60 GHz band, leading to Line-of-Sight operation and potential overheating and battery drain issues in devices using these frequencies.
Innovation Solution
Implementing Multi-Link Operation (MLO) in Access Points (APs) that enable Stations (STAs) to connect on multiple links, selectively using the 60 GHz band based on device information such as battery level and heat levels, and prioritizing energy-efficient transmissions to manage power consumption and heat management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If devices use 60 GHz band for high bandwidth communication, then network throughput is improved, but penetration loss and scattering increase
Solution Approach 1:
The patent segments the wireless communication system into multiple frequency bands (60 GHz band and at least one other band). The Access Point can select different bands based on channel conditions, dividing the communication task across multiple spectral segments to overcome the limitations of any single band's penetration loss and scattering characteristics.
Solution Approach 2:
The system dynamically changes the operating frequency parameter by switching between the 60 GHz band and other bands based on real-time channel conditions, device battery levels, and heat management requirements. This parameter adaptation allows the system to optimize between throughput and reliability trade-offs.
2Productivity
If devices operate on 60 GHz band, then high bandwidth communication is achieved, but device overheating and battery drain occur
Solution Approach 1:
The patent implements dynamic band selection where the Access Point continuously monitors device battery levels and thermal conditions. The system dynamically switches between 60 GHz and other bands based on real-time temperature and battery status, allowing the communication parameters to adapt to changing thermal and energy constraints.
Solution Approach 2:
The system incorporates feedback mechanisms where devices report their battery levels and thermal conditions to the Access Point. This feedback loop enables the Access Point to adjust the operating band accordingly, reducing power consumption and heat generation when devices are in thermal or energy critical states.
3Productivity
If devices use 60 GHz band for immersive metaverse and extended reality applications, then required high bandwidth is provided, but energy consumption increases
Solution Approach 1:
The patent applies partial action by using the energy-intensive 60 GHz band only when and where needed for immersive applications that require high bandwidth. For other applications or when devices are in energy-constrained states, the system uses alternative bands that consume less power, thereby applying the appropriate level of energy consumption partially rather than continuously.
Solution Approach 2:
The system changes the operational parameters by switching between frequency bands based on application requirements and device energy states. This allows immersive applications to utilize the high bandwidth of the 60 GHz band when available and appropriate, while falling back to more energy-efficient bands when power conservation is prioritized.
