Solution Overview
Problem
Existing solutions for improving Wi-Fi, cellular network, and broadcast television signal strength often require separate signal boosters, which are costly and difficult to install, and do not effectively address signal interference and distance-related issues.
Innovation Solution
A radio frequency signal booster that combines capabilities for Wi-Fi, cellular, and broadcast television signals, using shared components such as antennas, power supplies, and circuitry to amplify and process multiple frequency bands, and employs time division duplexing (TDD) and frequency division duplexing (FDD) circuits to enhance signal strength and coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate signal boosters are used for Wi-Fi, cellular, and broadcast television signals, then each signal type can be amplified independently, but the system becomes complex, costly, and difficult to install
Solution Approach 1:
The patent combines multiple signal booster functions (Wi-Fi, cellular, broadcast television) into a single integrated device. The amplifier is configured to receive and amplify multiple different signal types simultaneously through a shared antenna system, eliminating the need for separate booster devices for each signal type and reducing overall system complexity
Solution Approach 2:
The amplifier is designed as a universal device capable of handling multiple frequency bands and signal types. It includes circuitry that can process Wi-Fi signals, cellular signals, and broadcast television signals through a single unit, making one device perform the functions of multiple specialized devices
2Reliability
If multiple separate boosters are deployed, then each signal path can be optimized, but installation becomes difficult and costly
Solution Approach 1:
The patent integrates multiple signal processing functions into a single amplifier unit that can be installed in one location. The shared antenna system and unified amplifier design reduce the number of installation points and simplify the overall installation process compared to deploying multiple separate boosters throughout the space
Solution Approach 2:
The universal amplifier design accepts multiple signal types through a single interface and processing unit, reducing installation complexity. The device can be manufactured as a standardized unit that handles various signal types without requiring custom installation procedures for each signal type
3Reliability
If separate devices are used for different frequency bands, then each band can be optimized independently, but the cost increases
Solution Approach 1:
The amplifier is designed to handle multiple frequency bands (including Wi-Fi bands, cellular bands, and broadcast television bands) within a single device. The circuitry is configured to process signals across different frequency ranges simultaneously, eliminating the need to purchase and install separate devices for each frequency band
4Area of stationary object
If multiple boosters are used, then coverage can be extended to all areas, but the system requires centralized control and coordination
Solution Approach 1:
The patent consolidates multiple signal amplification functions into a single centralized amplifier that can extend coverage for multiple signal types simultaneously. This unified approach eliminates the need for complex coordination between multiple independent booster systems, as all signal types are processed through one controlled unit
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The combined signal booster improves network reception for multiple devices across different frequency bands and technologies, reducing the need for multiple boosters, simplifying installation, and enhancing signal strength and coverage, while allowing for centralized control of signal gain and attenuation.
Implementation Method 1
The amplifier is configured to amplify a Wi-Fi signal in a first frequency band, amplify a cellular signal in a second frequency band, and amplify a broadcast television signal in a third frequency band

AI summary
Provided herein are apparatus and methods for radio frequency signal boosters for cellular and broadcast television signals with Wi-Fi signals transmission function. Cell phone, Wi-Fi, and broadcast television signals are boosted and retransmitted over a shared antenna or over more than one antenna. In certain implementations, a multi-band signal booster is configured to provide signal path gain to at least three signal paths: a first signal path configured to receive a first time division duplexed Wi-Fi signal, a second signal path configured to receive a first frequency division duplexed mobile or cellular signal, and a second signal path configured to receive a broadcast television signal.
