All the Way to the Pacific: Czech wireless technology has once again proven its global relevance. In the Pacific Ocean — thousands of kilometers from Europe — IQRF® now forms the technological backbone of an autonomous monitoring system deployed at Christ University in Pacific in the Kingdom of Tonga. This fascinating story is featured in our podcast series Wireless, the Smart Way: A Guide to the World of IQRF®, highlighting international collaboration, resilient IoT solutions, and the global reach of Czech engineering.
A Unique Collaboration: Researchers from Ostrava in the Pacific
A research team from VŠB–Technical University of Ostrava (Faculty of Electrical Engineering and Computer Science) travelled across the globe to implement an advanced sensor system on the university campus in Tonga.
Their mission:
To build an autonomous wireless monitoring solution capable of operating in an extreme climate with limited local infrastructure.
The system continuously tracks: weather conditions, atmospheric parameters, structural stability of the building, long-term environmental trends.
What Makes the System Exceptional
Thanks to the integration of sensors and the IQRF® wireless mesh network, the team created a fully autonomous and maintenance-friendly solution — without installing a single cable.
1. Meteorological and structural-stability sensors
Installed on the roof and inside the building to monitor: temperature, humidity, air pressure, building tilt and structural changes.
2. Robust IQRF® mesh network — no cabling required
Mesh topology ensures reliable data transmission even when nodes lose direct connectivity. The system is resilient to interference, obstacles, and harsh weather.
3. Solar-powered, fully energy-independent operation
Small photovoltaic panels provide long-term autonomy, ensuring operation even in remote regions with unstable electricity supply.
4. Online visualisation with Grafana
A central microcomputer collects and stores all sensor data. Grafana dashboards allow authorized experts to access:
real-time environmental data, historical trends, long-term stability analysis — from anywhere in the world.
Why This Project Matters
Tonga is not just another deployment site — it represents a pilot IoT project with significant long-term value:
1. Foundation for scientific and educational cooperation
The project strengthens international partnerships and opens new doors for collaborative research.
2. Demonstration of Czech wireless excellence
IQRF® proves it can operate even where: infrastructure is limited, power is unstable, terrain is challenging.
3. Support for climate-resilience efforts
The system helps monitor how extreme weather and climate trends impact buildings and infrastructure. For regions vulnerable to climate shifts, autonomous sensing is becoming essential.
Tonga as a Proof of What’s Possible
This project showcases the powerful combination of: ultra-low-power mesh networking, solar-driven autonomy, intelligent sensing, Czech engineering and innovation.
IQRF® enables advanced environmental monitoring anywhere on Earth — even where cables, electricity, and stable connectivity are simply not available.
