Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies often fail to meet bandwidth needs by operating on a single band, limiting throughput and flexibility, especially for devices requiring higher bandwidth.
Innovation Solution
Implementing a method and system for simultaneous transmission and reception of data using multiple wireless bands, enabling joint or independent data transmission and supporting full duplex connections through frequency division duplex (FDD) mode.

Engineering Contradiction Analysis
1Productivity
If a single band is used for wireless communication, then device complexity is reduced and ease of operation is improved, but network throughput and bandwidth are limited
Solution Approach 1:
The patent segments the wireless communication system into multiple independent bands (2.4 GHz and 5 GHz), each with its own transceiver and channel access control. This allows simultaneous operation on multiple bands, increasing network throughput while managing complexity through structured segmentation of resources and control mechanisms.
Solution Approach 2:
The patent transitions from single-band operation to multi-band operation by adding the frequency dimension. Devices can now communicate simultaneously on multiple frequency bands, effectively multiplying the available bandwidth and throughput capacity without fundamentally changing the underlying communication protocol structure.
2Productivity
If multi-band operation is implemented, then network throughput and bandwidth are increased, but channel access control and network management become more complex
Solution Approach 1:
The patent applies different channel access control mechanisms to different bands based on their specific characteristics and traffic requirements. The AP can independently control channel access on the 2.4 GHz band versus the 5 GHz band, allowing optimized local management for each band while maintaining overall system coordination.
Solution Approach 2:
The patent implements feedback mechanisms where the AP monitors channel conditions, traffic load, and device performance on each band, then dynamically adjusts channel access control decisions. This feedback loop enables adaptive multi-band resource allocation that simplifies operation by automatically responding to changing network conditions.
3Productivity
If simultaneous transmission on multiple bands is enabled, then peak throughput is improved, but interference management and signal coordination become more difficult
Solution Approach 1:
The patent introduces the Access Point (AP) as an intermediary that coordinates simultaneous transmissions across multiple bands. The AP manages timing, frequency allocation, and signal synchronization between devices operating on different bands, ensuring reliable coordination while enabling peak throughput through parallel communications.
