Technologies Satellite communications (Iridium) | GNSS | Embedded systems | Mobile integration | Power management Define the Problem Users operating in remote environments required reliable communication beyond the reach of traditional cellular networks. Conventional smartphones lacked the satellite communication capability needed to support messaging

Overview Diagnosing and validating a subtle silicon-level timing issue that impacted wireless communication stability. Technologies LoRa | Embedded systems | RF communications | Debug and validation Define the Problem During development of a LoRa communication system, intermittent timing instability was observed when operating at lower spreading factors intended to increase communication throughput. The issue appeared sporadic and difficult to reproduce consistently. Diagnose

Overview Developing a robust remote update mechanism for connected devices operating over constrained networks. Technologies Firmware | Bootloaders | IoT | Embedded systems Define the Problem Remote devices required firmware updates over very low data-rate communication links, where interruptions could occur at any time. Diagnose the Root Cause Traditional update approaches risked incomplete installations and device failure if communication was interrupted. Key engineering ch

Overview Improving communication range while remaining within regulatory transmission limits. Technologies RF design | Antennas | Wireless communications | Embedded systems Define the Problem A wireless system required greater communication range but could not increase transmission power due to regulatory constraints. Diagnose the Root Cause Investigation showed inefficiencies in antenna performance and receiver sensitivity limiting effective range. Key engineering challenges

Objective Monitor the life and condition of panel air filters in industrial air handling systems, transitioning from time-based to service-based replacements with fault monitoring. Solution Innovisory developed a back-end dashboard system to monitor each system and panel filter condition. We began with a prototype system, capturing Filtrex’s requirements and creating a basic, low-cost platform for trialling. Feedback from the successful trial allowed us to refine the requirem

Overview: Designing and deploying a scalable, low-power monitoring platform that transformed industrial air filtration from time-based maintenance to condition-based servicing. Technologies LoRa | Low-power embedded systems | Cloud platform | Industrial sensing The Problem Industrial air handling systems traditionally rely on fixed maintenance schedules to replace panel filters, regardless of their actual condition. This often results in unnecessary servicing, increased opera
