What equipment was used to record the datasets?

All of the datasets were recorded using the same National Instruments NI PXIe-5663 revision G test equipment.

What information is required to unpack the datasets?

The recording files are binary files containing signed 16-bit integers (two's complement). These signed 16-bit integers represent pairs of unscaled inphase (I) and quadrature (Q) values of the complex baseband waveform. The complex waveform is represented by a series of these I/Q pairs.

The binary file is arranged as follows. Again, all values are signed 16-bit integers.

Sample 1 (I)
Sample 1 (Q)
Sample 2 (I)
Sample 2 (Q)
Sample 3 (I)
Sample 3 (Q)

What if an IoT protocol does not provide a unique ID?

The purpose of the Challenge is to use innovative ways to overcome this limitation.

What is the proper format for device ID's on the submission form?

List device IDs as four-digit hex values padded with zeros. For example, 1A hex must be submitted as 001A. If a protocol by convention typically represents device ID by decimal or binary, convert the value to hex when completing the submission form. The sample answer on the form was not intended to represent a protocol-compliant device ID but is simply an example of what the formatting must look like.
