Efficient utilisation of the Radio Frequency Spectrum (RF) resources is a crucial aspect in ensuring the smells co-existence among radio systems and expansion of capacity and coverage of the national Information and Communication Technology (ICT) wireless infrastructure. This collaboration project involving partners from the industry and academia, provides a country-wide distributed, passive, wide-band, low-cost spectrum sensing network infrastructure.

Objectives of this project

• To promote research and industrial innovation in spectrum engineering using advanced techniques such as Dynamic Spectrum Access, Machine Learning and Artificial Intelligence.
• To understand instantaneous and long-term spectrum usage patterns around the country; and
• To support the decision making process of policy makers, regulators and network operators.

The Sensing Infrastructure

The spectrum sensing infrastructure is built by utilising the CSIR's wide-band, low-cost spectrum monitoring technology demonstrator integrated with an online management platform. The infrastructure is capable of performing spectrum measurements ranging between 100 MHz to 3.8 GHz.

Each spectrum sensing node in the network iscapable of collecting near-real-time spectrum measurements and performs pre-processing at the edge level and forwards the pre-processed datasets to the cloud-based engine for further analysis.

The infrastructure provides and online portal for accessing the historical measurement datasets and remote access to the individual spectrum sensing nodes. The sensor icons on the map represent a location that a low-cost spectrum sensor is installed. Majority of the sensing devices are hosted by our university partners country-wide.
