Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in efficiently allocating bandwidth to spot beams, leading to underutilized capacity in some areas while others lack sufficient bandwidth to meet demand, due to rigid frequency reuse plans that are difficult to alter post-deployment.
Innovation Solution
Implementing a flexible bandwidth assignment system that re-allocates frequency and polarization combinations between spot beams based on demand, using reserved combinations that can be dynamically reassigned to optimize bandwidth usage across adjacent and overlapping coverage areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rigid frequency reuse plan is implemented, then the system structure is simple and reliable, but the bandwidth allocation cannot adapt to changing demand and leads to underutilized capacity in some areas while other areas lack sufficient bandwidth
Solution Approach 1:
The patent implements dynamic bandwidth allocation by allowing the bandwidth of spot beams to be changed after deployment. The system can reallocate bandwidth from spot beams with excess capacity to those with insufficient capacity, enabling adaptability to changing demand while maintaining a relatively simple overall system structure.
Solution Approach 2:
The patent changes the bandwidth parameter of spot beams dynamically. By allowing bandwidth to be reassigned between spot beams based on real-time demand, the system can optimize capacity distribution without fundamentally redesigning the frequency reuse plan, thus improving adaptability while controlling complexity.
2Productivity
If bandwidth is reallocated dynamically, then bandwidth utilization efficiency improves, but system complexity increases due to the need for real-time monitoring and reconfiguration
Solution Approach 1:
The system employs feedback mechanisms to monitor bandwidth usage in different spot beams and uses this information to make reallocation decisions. By continuously assessing demand and adjusting bandwidth allocation accordingly, the system achieves high utilization efficiency while managing complexity through automated feedback-driven control.
Solution Approach 2:
The bandwidth management system operates autonomously by automatically monitoring, assessing, and reallocating bandwidth based on demand signals from the network. This self-service capability enables efficient resource distribution without requiring manual intervention, improving productivity while containing operational complexity.
3Ease of manufacture
If frequency reuse plans are fixed during deployment, then hardware design is simplified, but post-deployment alterations are not feasible leading to inefficient bandwidth distribution
Solution Approach 1:
The patent segments the frequency reuse plan into fixed structural components and flexible bandwidth allocation components. The basic frequency reuse pattern remains fixed to maintain hardware simplicity, while the actual bandwidth assignment to individual spot beams is made variable and adaptable to post-deployment needs.
Solution Approach 2:
The system maintains a static hardware design for frequency reuse while implementing dynamic bandwidth allocation software/control mechanisms. This allows the physical layer to remain simple and manufacturable, while the operational layer provides post-deployment flexibility through real-time bandwidth reallocation capabilities.

AI summary
A wireless communication platform utilizes flexible bandwidth assignment to re-allocate bandwidth between spot beams. The platform may assign a first combination of frequency and polarization (FP) to a first spot beam and a second combination of frequency and polarization to a second spot beam that is adjacent and at least partially overlapping the first spot beam. The platform may assign to the first spot beam a reserved combination of frequency and polarization during a first time period, and at second time, assign the reserved combination to the second spot beam. The platform may also assign the reserved combination simultaneously to adjacent spot beams by managing user of the reserved combination by geographically isolated terminals in the spot beams. The platform may further assign different portions of the reserved combination to adjacent spot beams without geographical limitations.
