Slaven Damjanović, CEO and founder of GLAMOS, talks about building the world’s most advanced LoRaWAN testing tool—starting from his own need for better field deployment visibility.
Overview
When deploying LoRaWAN devices in the field, understanding where your network truly reaches—and how different antennas or spreading factors impact connectivity—is critical. Slaven Damjanović created GLAMOS Walker as a virtual IoT sensor to do exactly that. What began as a personal tool to map coverage in Croatian vineyards quickly became a must-have in the Helium community, known for its intuitive design and pro-level insight.
Key Topics Covered
- The origins of GLAMOS: solving the real-world problem of testing LoRaWAN deployments
- How GLAMOS Walker acts like a virtual IoT sensor, simulating device behavior in the field
- Use during the Helium boom: rapid demand from thousands of users trying to optimize their gateways
- Understanding LoRaWAN data: RSSI, spreading factor, and antenna gain as key variables in deployment
- Indoor coverage mapping: visualizing LoRaWAN signal strength room-by-room using 3D floorplans
- Spreading factor tradeoffs: SF10 vs SF7 and the impact on battery life—up to 20x difference
- Testing LoRaWAN devices before deployment: reducing risk by validating connectivity conditions
- Pressure during Helium’s rise: why field testing tools became critical for hotspot optimization
Business Insights
From agriculture to utilities, Slaven explains how GLAMOS enables smarter, faster deployments of LoRaWAN devices. With built-in data visualization tools and a simple UI, the Walker is both beginner-friendly and essential for pros. The episode offers a masterclass in deployment optimization for anyone serious about making LoRaWAN data work in the real world.
