Solution Overview
Problem
The high cost and regulatory hurdles associated with deploying fiber optic networks in developed communities, particularly in the 'last mile' connection from the central office to subscriber facilities, limit the widespread adoption of fiber broadband services.
Innovation Solution
Utilizing an unlicensed radio frequency spectrum, specifically the Citizens Broadband Radio Service (CBRS) band, to transmit fiber signaling data wirelessly through a radio bearer, facilitated by a base transceiver station that recognizes fiber broadband subscribers using a public land mobile network identifier, converting wireless signals to optical signals for connection to a fiber optic central office.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fiber optic cables are deployed through traditional wired infrastructure, then network capacity and reliability are improved, but deployment cost and complexity increase significantly
Solution Approach 1:
The patent introduces a wireless communication system as an intermediary between the fiber optic backbone and subscriber premises. The base transceiver station receives fiber signaling data and transmits it wirelessly through radio waves, eliminating the need for physical fiber deployment to every location while maintaining network reliability through hybrid fiber-wireless architecture
Solution Approach 2:
The patent replaces the mechanical installation of fiber optic cables with wireless radio frequency transmission. Instead of physically laying cables through infrastructure tunnels and poles, the system uses electromagnetic waves to transmit data, significantly reducing deployment complexity while maintaining high-speed connectivity
2Adaptability or versatility
If fiber optic cables are deployed in developed communities, then broadband coverage is improved, but regulatory hurdles and permitting costs increase
Solution Approach 1:
The wireless communication system acts as an intermediary that bypasses traditional wired infrastructure requirements. By using radio frequency transmission through base transceiver stations, the system can provide broadband coverage in developed communities without needing to navigate complex underground utility routing and structural installation hurdles
Solution Approach 2:
The patent changes the transmission medium from physical fiber optic cables to electromagnetic waves. This parameter change allows the system to operate in existing radio frequency spectrum (including unlicensed bands), avoiding the need for new physical infrastructure and reducing regulatory permitting requirements associated with cable installation
3Ease of manufacture
If wireless communication is used for last mile connection, then deployment cost is reduced, but data transmission capacity may be limited
Solution Approach 1:
The patent segments the network into fiber backbone infrastructure and wireless access components. The high-capacity fiber network handles bulk data transmission to base transceiver stations, while wireless segments provide last-mile connectivity. This segmentation allows cost-effective deployment while maintaining overall high transmission capacity through the fiber-wireless hybrid architecture
Solution Approach 2:
The patent merges fiber optic technology with wireless communication systems to create a hybrid network. The combination leverages the high capacity of fiber for backbone transmission and the deployment flexibility of wireless for last-mile connection, achieving both cost reduction and maintained data transmission capacity
