Solution Overview

Problem

Wireless communication technologies, such as WWAN and WLAN, often fail to provide uniform coverage within buildings due to frequency and physical property limitations, preventing seamless communication between devices supporting different protocols.

Innovation Solution

A method and system that convert wireless signals between WWAN and WLAN protocols using a coaxial protocol for transmission over coaxial cables, allowing signals to be received and transmitted in different radio frequency spectra, enabling communication within buildings by using a combination of antennas and conversion devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If WWAN signals are transmitted using exterior antennas, then coverage area is improved, but signal penetration into buildings deteriorates

Engineering Contradiction:
Improvecoverage areaVSAvoidsignal penetration
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The patent introduces a cable television network as an intermediary medium to carry WWAN signals from exterior antennas into buildings. The coaxial cables act as a mediator that bypasses the penetration problem by providing a dedicated physical pathway through the building structure, allowing signals to be delivered reliably to interior locations without relying on wireless penetration through walls and roofs.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If different wireless protocols (WWAN and WLAN) are used, then device compatibility is improved, but interoperability between protocols deteriorates

Engineering Contradiction:
Improvedevice compatibilityVSAvoidprotocol conversion
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent makes the cable television network universal by enabling it to carry multiple wireless protocol types (both WWAN and WLAN signals) through the same physical infrastructure. This multi-functionality allows the network to serve dual purposes: delivering broadband internet access via WWAN while simultaneously supporting local wireless communications via WLAN, eliminating the need for separate dedicated networks for each protocol type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The cable television network serves as an intermediary that enables protocol interoperability. By converting WWAN signals into formats suitable for coaxial cable transmission and then converting them back to appropriate wireless or wired formats at the destination, the cable network mediates between different protocol domains, allowing devices using different protocols to communicate through a common infrastructure.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If coaxial cables are used for signal transmission, then signal stability is improved, but installation complexity deteriorates

Engineering Contradiction:
Improvesignal stabilityVSAvoidinstallation complexity
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The patent leverages the self-service aspect of existing cable television infrastructure. Rather than requiring new installation work, the system utilizes the already-deployed coaxial cable network that penetrates buildings for television and internet service. This approach allows the WWAN signal distribution system to piggyback on existing installations, avoiding the need for new cable routing while still providing stable signal transmission through the proven coaxial medium.

Inventive Principle:
Principle #25Self-service

AI summary

Various embodiments of systems, devices, and methods are described for wireless communication. In one example a first wireless signal is received in a first radio frequency spectrum using a first antenna exterior to a building. The first wireless signal is associated with a first wireless protocol. The first wireless signal is converted into a first intermediate signal associated with a coaxial protocol. The first intermediate signal is transmitted to an interior of the building using a coaxial cable. The first intermediate signal is converted into a second signal associated with a second wireless protocol. The second signal is then transmitted in a second radio frequency spectrum using a second antenna interior to the building. The second signal is transmitted using the second wireless protocol.
