Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data communication services face limitations in achieving high data rates and symmetry due to the design of existing coaxial cable infrastructure, which restricts bandwidth and requires costly upgrades to support increasing user demands for enhanced services, especially in urban environments where extensive replacement of coaxial cables with optical fiber is necessary.
Innovation Solution
The method involves leveraging existing coaxial cable infrastructure by up-converting RF signals to wider frequency bands, such as 802.11ax and 3GPP LTE/5G NR bands, and dynamically reallocating bandwidth to support ultra-high data rate services, enabling symmetric operation and mobility through the use of advanced wireless technologies like Wi-Fi 6 and 3GPP protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing coaxial cable infrastructure is used, then device complexity is reduced and ease of manufacture is improved, but data rate capability and bandwidth are limited
Solution Approach 1:
The patent changes the operational parameters of the coaxial cable system by up-converting RF signals to wider frequency bands (e.g., 802.11ax bands, 3GPP LTE/5G NR bands). This parameter change enables the existing coaxial infrastructure to support ultra-high data rate services without physical replacement, thereby improving productivity while avoiding infrastructure complexity increases
Solution Approach 2:
The patent makes the existing coaxial cable infrastructure multi-functional by enabling it to support both traditional cable services and ultra-high data rate wireless services through frequency up-conversion. This universality allows a single infrastructure to serve multiple purposes, improving data rate capability without requiring separate infrastructure systems
2Productivity
If coaxial cable infrastructure is replaced with optical fiber, then data rate capability and bandwidth are improved, but capital expenditure and implementation cost increase significantly
Solution Approach 1:
The patent uses software-based frequency up-conversion and signal processing techniques that can be deployed on existing infrastructure rather than investing in expensive optical fiber replacement. This approach treats the coaxial infrastructure as a reusable asset that can be enhanced through software/firmware updates, significantly reducing capital expenditure while maintaining improved bandwidth capacity through efficient spectrum utilization
3Productivity
If frequency spectrum is allocated for traditional cable services, then service reliability is maintained, but data rate capability for ultra-high speed services is limited
Solution Approach 1:
The patent segments the frequency spectrum into multiple bands, allocating different portions for traditional cable services and ultra-high data rate services. By dividing the spectrum resources and using frequency up-conversion techniques, the system maintains reliable traditional services in lower bands while enabling ultra-high data rates in higher bands, thus achieving both goals simultaneously

AI summary
Premises apparatus and methods for providing aggregated high-bandwidth, low-latency, data service over a content delivery network including existing wireline infrastructure. In one embodiment, a network architecture having service delivery over at least portions of extant hybrid fiber coax (HFC) infrastructure is disclosed, which includes standards-compliant ultra-low latency and high data rate services (e.g., 3GPP and IEEE Std. 802.11 services) via a common service provider. In one variant, an expanded frequency band (e.g., 1.6 GHz in total bandwidth) is used over the coaxial portions of the HFC infrastructure, which is allocated to two or more sub-bands. Premises apparatus are used to support multi-service integration (e.g., aggregation of mobile wireless, premises, and other services), as well as incipient IoT applications and technologies.
