IoTSensing Project Results. Radio Spectrum Sensing Free Datasets:
SpectrumHive LoRa Dataset
This dataset comprises 156,000 radio signal frames using the CSS LoRa modulation with spreading factors from 7 to 12, with 26,000 signal frames for each LoRa SF.
The LoRa signals are synthetically generated using Bassel Al Homssi library under Matlab environment [1]. Each signal frame consists of 4,096 complex samples, captured at a sampling rate of 1 Msps, with a signal-to-noise ratio (SNR) ranging from -20 dB to 30 dB with an increment of 2 dB. The dataset incorporates Rician fading and clock offsets between -5 and +5 ppm, with each frame having normalized power. The dataset is stored in MAT files, with each file containing two variables:
-IQ samples: Stored as a complex double array.
-Label: Provided in categorical format.
This dataset was used to train and evaluate a CNN for LoRa SF detection, which obtained a live inference detection accuracy of 99.16% using SX1276 LoRa transceivers.
SpectrumHive_IoT_Dataset_IQstream Dataset
This dataset comprises 120,000 radio signal frames spanning 11 modulation classes and noise. The modulation classes included are: QPSK, DBPSK, GFSK, 16QAM, 64QAM, CSS LoRa SF7, CSS LoRa SF8, CSS LoRa SF9, CSS LoRa SF10, CSS LoRa SF11, and CSS LoRa SF12.

Scope of the IoTSensing research project
The IoTSensing project entails the design, implementation and testing of spectrum sensing AI algorithms that are able to perform radio spectrum sensing with the main purpose to increase the performance level of large-scale high-density IoT networks. The algorithms will be validated in real operating conditions and will integrate advanced machine learning and deep learning architectures to achieve the highest level of performance. The novel platform will also integrate an interface to visualize and analyze IoT radio spectrum usage, detect interference, and generate detailed reports on radio spectrum occupancy and even radio channel allocation patterns.
”Efficient spectrum sensing is the backbone of modern wireless communication. In a world where connectivity fuels innovation, the ability to intelligently manage and optimize radio frequencies is key to unlocking the full potential of emerging technologies like IoT, 5G, and beyond.”
