Solution Overview

Problem

Existing wireless communication systems that utilize shared frequency spectrum face challenges in areas without reliable Internet connectivity, as they require Internet access to determine available channels, limiting their deployment in rural or infrastructure-scarce regions.

Innovation Solution

A system where a vehicle, such as a satellite, UAV, or land vehicle, registers wireless networks, queries a database for shared frequency spectrum information when connected to the Internet, and communicates this information back to the network when within range, enabling wireless networks to access shared frequency spectrum without relying on continuous Internet connectivity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a wireless network queries a database via the Internet to determine available channel information, then the network can obtain accurate shared frequency spectrum information, but the network cannot operate in areas without Internet connectivity

Engineering Contradiction:
Improveavailability of shared frequency spectrum informationVSAvoiddeployability in areas without Internet connectivity
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

A vehicle (satellite, UAV, or land vehicle) acts as an intermediary between the wireless network and the database. The vehicle collects available channel information from the database when connected to the Internet, stores it locally, and delivers it to the wireless network when within communication range, eliminating the need for direct Internet connectivity at the network location

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The vehicle performs preliminary actions by querying the database and collecting available channel information in advance, before the wireless network needs to use the information. This allows the network to receive pre-collected information without requiring Internet access at the time of use

Inventive Principle:
Principle #10Preliminary action

2Reliability

If a wireless network requires continuous Internet connectivity to access shared frequency spectrum, then the network can always obtain updated channel information, but the network cannot be deployed in rural or infrastructure-scarce regions

Engineering Contradiction:
Improveaccess to updated channel informationVSAvoidease of deployment in rural areas
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The vehicle serves as a mobile intermediary that bridges the gap between Internet-connected environments and remote areas. It collects information where Internet access is available and delivers it to remote locations, making deployment in rural areas feasible without requiring local Internet infrastructure

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system transitions from a static requirement for local Internet connectivity to a dynamic model where information is collected and delivered by a moving vehicle. The vehicle dynamically adjusts its position to first access the Internet, then deliver information to the remote wireless network

Inventive Principle:
Principle #15Dynamics

3Productivity

If the vehicle frequently enters and exits the communication range of the wireless network, then the network can receive updated spectrum information, but the system complexity increases due to registration and communication range management

Engineering Contradiction:
Improvefrequency of information updatesVSAvoidregistration and communication range management
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The vehicle autonomously manages its own registration with the wireless network and its own communication range monitoring. When the vehicle enters the communication range, it automatically registers and delivers information; when it exits, it automatically deregisters. This self-service approach reduces the complexity burden on the wireless network

Inventive Principle:
Principle #25Self-service

AI summary

Disclosed herein is a system for providing information related to a shared frequency spectrum to a wireless network that lacks Internet connectivity. The system may include one or more processors and memory including instructions that are executable by the one or more processors to perform operations. The operations may include receiving registration of the wireless network when a vehicle is within a communication range of the wireless network, querying a database on behalf of the wireless network when an Internet connection is available, receiving query results including the information related to the shared frequency spectrum, and communicating the information related to the shared frequency spectrum to the wireless network when the vehicle or a proxy of the vehicle is again within the communication range of the wireless network.
