Mobile Repeater Telephone Ad-Hoc Network Topology
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ad-hoc networks of mobile phones are inefficient in sparsely populated or catastrophe-stricken areas due to reliance on cellular antenna towers, which can be damaged or unavailable, leading to communication breakdowns and high costs, especially when users are close but unable to connect directly.
Innovation Solution
An ad-hoc network system where mobile repeater phones with integrated transmitters, receivers, and repeaters use geographic maps and signal attenuation data to establish and maintain connections, allowing direct or alternative routes between phones, even in hilly or obstructed areas, and can switch wavelengths to optimize signal strength, and utilize Internet Protocol telephony for global connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cellular telephone antenna towers are used for communication, then communication coverage is provided, but communication costs increase and reliability decreases when towers are damaged or unavailable
Solution Approach 1:
The patent introduces mobile phones as intermediary devices that can relay communications between users. When cellular towers are unavailable, mobile phones form ad-hoc networks to serve as intermediate communication nodes, eliminating dependency on tower infrastructure while maintaining communication capability.
Solution Approach 2:
The patent segments the communication network into individual mobile phone nodes that can operate independently. Each mobile phone becomes a self-contained communication unit capable of direct peer-to-peer communication or relaying through other phones, breaking away from the centralized tower-dependent architecture.
2Reliability
If mobile phones form ad-hoc networks without cellular towers, then communication cost decreases and reliability improves, but network coverage and signal strength deteriorate in sparsely populated or obstructed areas
Solution Approach 1:
The patent extends network coverage by utilizing the mobility dimension of mobile phones. Users can physically move to establish better signal connections, and the network dynamically routes communications through multiple phones in three-dimensional space, overcoming terrain obstructions and expanding effective coverage area.
Solution Approach 2:
The patent uses mobile phones as intermediary relay nodes to extend network coverage. When direct communication between two phones is blocked by terrain or distance, intermediate phones relay the signal through multiple hops, effectively extending the network's reach into areas that would otherwise be unreachable.
3Productivity
If mobile phones act as repeaters for multiple simultaneous calls, then network capacity increases, but device complexity and processing requirements increase
Solution Approach 1:
The patent makes mobile phones universal devices that can simultaneously function as end-user telephones and as network repeaters/relays. The same hardware components (transmitter, receiver, processor) used for normal phone calls are also utilized for repeating and relaying communications, eliminating the need for separate repeater equipment and reducing overall system complexity.
Solution Approach 2:
The patent merges the functions of telephone communication and signal repetition into a single integrated system. Mobile phones combine both end-user communication capabilities and network infrastructure functions, allowing simultaneous handling of multiple calls through the same device without requiring separate specialized hardware.
4Device complexity
If mobile phones use single transceiver for communication, then device simplicity is maintained, but ability to handle multiple simultaneous calls and provide reliable communication deteriorates
Solution Approach 1:
The patent implements dynamic resource allocation where mobile phones with single transceivers dynamically switch between communication modes. The system dynamically routes calls through different available phones based on current network conditions, allowing reliable simultaneous call handling through coordinated time-division and frequency-division strategies rather than static hardware configurations.

Function Achieved in This Case
This system enables reliable, efficient, and cost-effective communication in areas without cellular towers, maintaining connections through alternative routes and ensuring minimal delay, especially in emergency situations, by utilizing the repeaters and transmitters within the mobile phones to form dense networks and prioritize calls.

AI summary
An ad-hoc network that includes a plurality of telephones at least one of which is a mobile repeater telephone for establishing a first telephone connection line between a first caller telephone and a first receiver telephone, and for simultaneously establishing at least one second telephone connection line between a second caller telephone and a second receiver telephone. A subset of all the mobile repeater telephones in the network each have its own unique code and a subset of the unique codes are known to a subset of all mobile repeater telephones in the ad-hoc network. The mobile repeater telephones have a software program stored on the processors of the telephones or a database that is accessible by the telephones. The software program includes a geographic map in electronic form of the area of the network and includes data about topography and obstacles and how much the obstacles attenuate the signal.
