Directional Wireless Radio Alignment via Aural Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of microwave radios for optimal signal strength is challenging for solo installers, as existing methods lack accuracy and visibility, often requiring two people to manage signal alignment, and prior solutions like LED indicators or web browser monitoring are inadequate for solo operations.
Innovation Solution
A smartphone-connected system that uses aural indications, such as varying tones or voice outputs, to guide the installer in aligning a directional wireless radio with a second wireless radio, allowing hands-free operation and improved accuracy through periodic or demand-based signal strength feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If LED indicators or web browser monitoring are used for signal alignment, then signal strength can be monitored, but solo operation becomes difficult and requires two people
Solution Approach 1:
The patent replaces visual monitoring systems (LED indicators, web browser interfaces) with an acoustic feedback system using audio outputs from the mobile device. This substitution allows the installer to receive signal strength information through sound while keeping hands free for physical radio adjustment, enabling solo operation without requiring a second person to monitor visual displays.
Solution Approach 2:
The mobile device acts as an intermediary between the wireless radio system and the installer. It receives signal strength data from the radio, processes it, and provides feedback through audio outputs. This intermediary function consolidates both monitoring and communication roles into a single handheld device, eliminating the need for a second person while maintaining accurate signal monitoring.
2Measurement precision
If visual monitoring methods are used, then signal strength can be observed, but hands-free operation is limited and installation time increases
Solution Approach 1:
The system replaces visual monitoring with acoustic feedback delivered through the mobile device's audio output. This allows the installer to maintain hands-free operation while receiving continuous or periodic signal strength updates, enabling simultaneous monitoring and physical adjustment without pausing to check visual displays.
Solution Approach 2:
The system can provide signal strength feedback at periodic intervals or on-demand based on installer input. This periodic feedback mechanism maintains accurate signal monitoring while allowing the installer to focus on physical alignment tasks without continuous visual attention, reducing installation time while preserving measurement precision.
3Measurement precision
If two people are used for alignment, then signal monitoring accuracy improves, but installation cost and complexity increase
Solution Approach 1:
The mobile device provides self-service functionality by integrating signal strength monitoring, processing, and audio feedback delivery into a single unit. The installer uses the device autonomously to obtain accurate signal information without requiring a second person, thereby reducing installation team complexity while maintaining alignment accuracy.
Solution Approach 2:
The mobile device performs multiple functions: it acts as a signal strength receiver, data processor, audio output device, and user interface all in one. This multi-functionality consolidates the roles previously requiring two people into a single tool, reducing installation complexity while preserving measurement precision.

AI summary
A method and system are provided. The method includes receiving a signal strength corresponding to a long range wireless link established between a first directional wireless radio and a second wireless radio, the signal strength varying over time as the first directional wireless radio is aligned with a second wireless radio by an installer, and producing a sound indicator indicative of the signal strength. The sound indicator varies over time as the first directional wireless radio is aligned with the second wireless radio.
