Integrating Wireless Microcells into FTTX Fiber Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current practices involve separate fixed and wireless communication networks for services like telephony and internet access, which are complicated and less reliable, whereas integrating wireless connections into high-capacity fixed networks at intersection points could provide a simpler and more efficient solution.
Innovation Solution
Integrating low-powered microcells, such as IEEE 802.11 a/b/g/n Wi-Fi or 802.16 Wi-Max networks, to form a contiguous wireless coverage along traffic ways, leveraging the existing or installed fixed network as a backbone for delivering high-bandwidth mobile services, including video, audio, and data, and utilizing IPv6 for Quality Of Service and mobility features.

Engineering Contradiction Analysis
1Reliability
If separate fixed and wireless communication networks are deployed, then each network can be optimized independently, but the overall system complexity increases and reliability decreases
Solution Approach 1:
The patent merges separate fixed and wireless communication networks into an integrated network architecture. Fixed network infrastructure (fiber optics, cable systems) is combined with wireless access points and microcells to create a unified network that delivers both wired and wireless services through a common backbone, reducing overall system complexity while maintaining reliability.
Solution Approach 2:
The integrated network infrastructure serves multiple functions simultaneously. The fixed network backbone provides high-capacity transport for both wired connections and wireless backhaul, while wireless access points deliver both data and voice services. This multi-functionality reduces the need for separate dedicated infrastructure for each service type.
2Productivity
If wireless networks are deployed separately from fixed networks, then wireless coverage can be extended, but service delivery efficiency decreases
Solution Approach 1:
The patent combines wireless access points with fixed network infrastructure at integration points such as cable hubs and fiber nodes. This merging allows wireless traffic to be carried over high-capacity fixed network backbones, improving service delivery efficiency by leveraging the bandwidth and reliability of wired infrastructure for wireless service delivery.
Solution Approach 2:
Fixed network infrastructure acts as an intermediary between the core network and wireless access points. The integrated network architecture uses fixed network elements (cable hubs, fiber nodes) as mediators to connect wireless microcells and access points to the core network, enabling efficient service delivery through a bridging infrastructure.
3Use of energy by moving object
If low-powered microcells are used to form wireless coverage, then power consumption is reduced, but coverage continuity requires more nodes
Solution Approach 1:
The patent segments the wireless coverage area into multiple overlapping zones served by low-powered microcells and access points. Each microcell covers a localized area with reduced power requirements, while the segmentation allows for modular deployment and integration with distributed fixed network infrastructure points, reducing overall power consumption while maintaining coverage continuity.
Solution Approach 2:
The patent utilizes the spatial dimension by deploying microcells in an overlapping blanket pattern along traffic ways and right-of-ways. This dimensional approach to network deployment allows low-powered nodes to achieve continuous coverage through strategic positioning and overlap, rather than requiring high-power single-point transmission, thereby reducing power consumption while maintaining coverage.
Data Source
AI summary
An approach to integrate a wireless data network blanket into the high-capacity fixed FttX (Fiber-to-the-Premises/Curb/Neighborhood) network at intersection points throughout the overlay rather than interconnecting them as two disparate networks in order to provide a plurality of data containing video, audio, voice communications, broadcast radio programming, and data both fixed and mobile. This approach is applicable to PON (Passive Optical Networks) and active networks alike, though the implementations vary slightly. Considerations must still be made for security.
