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

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.

• Helium Global IoT Coverage - Want to know if Helium coverage exists where you need it? Check out this map!
• Helium Foundation - The Helium Foundation's IoT Working Group (IOTWG) has generously provided support for the first 6 months of shows, please go check them out and consider using the Helium LoRaWAN as a primary or backup on your next deployment. With over a quarter million gateways deployed worldwide, it's likely that you have and can use Helium coverage.
• Support The Show - If you'd like to support the MetSci Show financially, here's where you can donate on a one-time or an ongoing basis. Thank you!
• MetSci Show - If you'd like to use our IoT or AI Data Value calculators, or you'd like to contact me, the MetSci Show site is the best way to do it.
• MeteoScientific Console - Use LoRaWAN - The MeteoScientific Console allows you to use LoRaWAN today. As long as you have Helium coverage (and you probably do, about 90% of populated areas in the world have a gateway within 2 miles), you can onboard a sensor.
