Radio propagation and spectrum allocation
My doctoral research considered how to allocate spectrum when propagation and interference are modelled under realistic conditions. The thesis is available below.
Spatial reconstruction
Reach Map uses known positions and times to bound possible movement.
From my research
Examples of my research simulations. These illustrate modelled propagation, reachability and interference; they are not field measurements.
Radio coverage in Victoria Square
A 3D view of simulated coverage from a north-facing ground transmitter in Victoria Square. Buildings are modelled as solid concrete; open spaces and reflected paths shape the coverage.
3D model derived from Google 3D Tiles; propagation simulated with Sionna RT.

Radio coverage around Adelaide Oval
A 3D view of simulated coverage from a north-facing ground transmitter at Adelaide Oval. Reflections and gaps in the stadium structure allow paths into areas without direct line of sight.

A drone above Victoria Square
Simulated ground coverage from one omnidirectional drone antenna above Adelaide CBD. The yellow drone marks the transmitter location.

Interference between five drones
Four views of the same simulated instant at 3 minutes near Halls Gap. Colours show the mutual worst signal-to-interference ratio; drone icons are enlarged for visibility.

Walking reachability and radio propagation
Adelaide CBD: top left shows the scene before the initial time, top right at 00:00:00, and the lower view at 00:07:00. Possible walking reach is combined with simulated propagation, rather than an exact recovered path.

Driving reachability around Halls Gap
Possible driving reach combined with simulated radio propagation. Panels retain their original order: 00:00:00, 00:00:30, 00:05:00 and 00:10:00, read left to right across each row.

Two transceivers in Adelaide
At 2 minutes of possible driving, the upper views show simulated path loss for each transceiver. The lower view shows their signal-to-interference ratio.

An Exploration of the Spectrum Management Resource Allocation Problem under Realistic Conditions
My PhD examined spectrum allocation under realistic conditions, using radio propagation models to account for interference and the surrounding environment.
Reach Map
An algorithm for mapping where movement was possible between known positions and times. Presented at DFRWS APAC in Brisbane, 2024. It describes possible movement, rather than recovering an exact path.
Line-of-Sight Propagation Modelling From Terrain Elevation Data
