Solution Overview
Problem
Current methods for certifying RF signal coverage in buildings are labor-intensive, requiring manual inspection and data recording, which is inefficient and prone to errors.
Innovation Solution
A method and system that superimpose a grid on a floor plan, assigning identifiers to sectors, where a test unit transmits and receives RF signals to determine signal strength and quality, automating the logging and reporting process, and allowing for digital encoding and modulation to assess signal criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual inspection methods are used for RF certification, then the process can be performed with simple equipment, but the labor intensity and time required increase significantly
Solution Approach 1:
The patent replaces manual mechanical inspection processes with an automated electronic system. A test unit with RF transmitter, receiver, and processor automatically performs signal measurements, sector identification, and data logging, eliminating the need for inspectors to manually walk through buildings and record data on paper or digital devices.
Solution Approach 2:
The test unit operates autonomously to perform certification functions. It automatically identifies sectors using encoded signals, measures RF signal strength, determines pass/fail criteria, and logs results without requiring continuous human intervention. The system serves itself by completing the entire certification workflow independently.
2Device complexity
If manual data recording is used during inspection, then equipment requirements remain simple, but accuracy and reliability of recorded data decrease
Solution Approach 1:
The patent replaces manual data recording with automated electronic measurement and logging. The test unit's processor automatically captures RF signal strength values, compares them against predetermined criteria, and records results in digital format, eliminating human errors in reading, transcribing, and interpreting measurement data.
Solution Approach 2:
The system incorporates automated feedback mechanisms where the processor continuously monitors RF signal measurements, compares them against stored criteria, and immediately determines pass/fail status. This real-time feedback loop ensures accurate and consistent evaluation without relying on inspector judgment or manual analysis.
3Productivity
If automated RF testing is implemented, then certification speed and accuracy improve, but system complexity and initial cost increase
Solution Approach 1:
The test unit is designed as a multi-functional device that combines RF transmission, reception, signal processing, sector identification, criteria evaluation, and data logging in a single integrated system. This universal device performs multiple certification functions simultaneously, reducing the need for separate specialized equipment and simplifying the overall system architecture.
Solution Approach 2:
The patent segments the certification process into distinct functional modules within the test unit: an RF transmitter for sending test signals, an RF receiver for capturing signals, a processor for analysis, and a logging system for data storage. This modular segmentation allows each component to be optimized independently while working together as an integrated system.
4Device complexity
If inspectors manually navigate and identify sectors, then no additional positioning equipment is needed, but the time required to complete certification increases
Solution Approach 1:
The patent replaces manual sector identification with automated electronic positioning. The test unit uses encoded sector identifiers transmitted from fixed locations throughout the building to automatically determine which sector is being tested, eliminating the need for inspectors to manually navigate, locate, and identify sectors using floor plans or visual cues.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach streamlines the certification process, reducing manual labor and increasing accuracy by automating the testing and logging of RF signal coverage across sectors, enabling efficient and reliable certification of RF signal coverage in buildings.
Implementation Method 1
The test unit transmits an RF test signal to a base unit located outside the structure
Implementation Method 2
The RF test signal as received by the base unit is analyzed to determine whether it satisfies a first predetermined criterion

AI summary
A method and system of certifying RF coverage in a structure. A grid is superimposed on a floor plan of a structure to be certified. Each sector in the grid is given an identifier. A test unit is placed in one of the sectors. An RF test signal is transmitted from the test unit to a base unit located outside the structure. The RF test signal as received by the base unit is analyzed to determine whether it is satisfactory. An RF reply signal is transmitted from the base unit to the test unit. The reply signal as received by the test unit is analyzed to determine whether it is satisfactory. This process is repeated for each sector of the grid.
