Today's spectrum measurements are mainly performed by governmental agencies which drive around using expensive specialized hardware. Each country creates and maintains its own national frequency allocation plan which describes how the EM spectrum shall be used. Despite, the EM spectrum is well-organized in terms of frequency allocation, its actual usage in different geographical places and times is not well-known at all. The idea of distributed spectrum monitoring has recently gained attention to capture the real-time usage of the wireless spectrum at large geographical scale.

We propose to analyze, design and build a distributed sensoring platform based on low-cost hardware nodes to analyze the spectrum collaboratively. The main advantage of low-end distributed solutions is that they may allow to create a wide-scale and real-time spectrum monitoring system. Collaborating to reach a common goal has the potential of:

• Reduce the time to monitor the whole spectrum.
• Reconstruct biggest wideband or
• detect and confirm anomalies in the spectrum.

We aim to reach this goal addressing the following fundamental research questions:

• How to synchronize the low-cost sensors for scanning the spectrum collaboratively.
• How to fuse the spectrum data in the back-end collected by the sensors
• Generate smart decisions to improve the efficiency to scan the spectrum.

During the activity we will talk about the challenges of the project, how to solve them and we will tell the actual state of the project. Also we could show a live demo of one of ours sensors working.
