Solution Overview
Problem
Conventional methods for providing broadband services to customer premises using wires or fibers are often limited by access constraints, construction costs, and regulatory delays, leading to revenue loss for service providers.
Innovation Solution
A dual frequency wireless transportation system that initially uses unlicensed radio frequencies for data transmission and switches to licensed frequencies when service levels degrade, ensuring continuous service while minimizing costs by avoiding upfront licensing fees.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wire or fiber construction is used to provide broadband service, then service reliability is improved, but construction cost and regulatory delays increase
Solution Approach 1:
The patent replaces the mechanical construction system (trenching, laying wire/fiber) with an electromagnetic wave-based wireless system. The dual-frequency wireless transportation system transmits data signals through air using licensed and unlicensed radio frequencies, eliminating the need for physical infrastructure construction while maintaining service reliability.
Solution Approach 2:
The patent introduces wireless communication as an intermediary solution between the service provider and customer premises. Instead of directly connecting via wire/fiber, the system uses radio frequency waves as an intermediary transmission medium, allowing data to be transmitted through the air without physical contact with the customer's property.
2Ease of manufacture
If unlicensed radio frequency is used for wireless transmission, then construction cost is reduced, but service quality deteriorates due to congestion
Solution Approach 1:
The patent implements a dynamic frequency selection mechanism where the system automatically switches between unlicensed and licensed radio frequencies based on service quality requirements. When unlicensed frequencies provide sufficient service, they are used to minimize cost; when congestion degrades service quality, the system transitions to licensed frequencies, creating a flexible adaptive system.
Solution Approach 2:
The patent changes the operating parameter (radio frequency type) from fixed to variable. The system can operate on unlicensed frequencies (2.4 GHz, 5.8 GHz) for cost-effective deployment and switch to licensed frequencies (6 GHz, 18 GHz, 38 GHz) when service quality requires it, allowing optimization of both cost and performance based on actual conditions.
3Reliability
If licensed radio frequency is used for wireless transmission, then service quality is improved, but operational cost increases due to licensing fees
Solution Approach 1:
The patent applies partial use of licensed frequencies only when necessary to maintain service quality. Instead of continuously using expensive licensed frequencies, the system uses them partially - only when unlicensed frequencies become congested and service quality deteriorates. This minimizes operational costs while ensuring service quality is maintained when required.
Solution Approach 2:
The patent creates a dynamic cost-management system where the operational cost (licensing fees) varies based on actual service quality requirements. The system adapts its frequency usage pattern, paying licensing fees only when unlicensed alternatives are insufficient, thereby optimizing the balance between service quality and operational expenditure.
4Ease of operation
If wireless transportation system is implemented, then access to customer premises is improved, but service reliability may deteriorate due to frequency congestion
Solution Approach 1:
The patent segments the radio frequency spectrum into multiple bands (unlicensed 2.4 GHz, unlicensed 5.8 GHz, licensed 6 GHz, licensed 18 GHz, licensed 38 GHz) to provide diverse transmission paths. This segmentation allows the system to distribute traffic across multiple frequency channels and switch between them based on congestion levels, maintaining service reliability while preserving wireless access advantages.
Solution Approach 2:
The patent uses frequency diversity as an intermediary mechanism to resolve the conflict between wireless access and service reliability. By introducing multiple frequency bands as intermediary transmission channels, the system can maintain reliable service through frequency switching when congestion occurs on any single channel, while still preserving the wireless access benefit.

the licensed radio frequency may be used to transmit information from the first point to the second point in the point-to-point configuration
Data Source
AI summary
Wireless information transportation may be provided. An unlicensed radio frequency may be used to transmit information from a first point to a second point. Then, the unlicensed radio frequency may be determined to no longer provide a sufficient service level. Next, a license to operate in a licensed radio frequency may be purchased when it is determined that the unlicensed radio frequency no longer provides the sufficient service. The license may limit the use of the licensed radio frequency to a point-to-point configuration. Using the unlicensed radio frequency to transmit information from the first point to the second point may be discontinued when it is determined that the unlicensed radio frequency no longer provides the sufficient service level. Then the licensed radio frequency may be used to transmit information from the first point to the second point in the point-to-point configuration when use of the unlicensed radio frequency is discontinued.
