Working with BT on propagation of signals from indoor small cells and optimization of cell positions. Hayley graduated with an MMath from the University of Sussex in 2016. Her undergraduate dissertation was on “Evolving surface finite element analysis of a semi-linear parabolic equation”. Outside of mathematics Hayley enjoys rugby, adventures and watching Disney films.

Research project title:
Optimisation of wireless router location

Supervisor(s):
Chris Budd, Robert Watson, Keith Briggs

Project description:
Recent developments in high frequency antennas for wireless communication could enable users to have stronger connections. However, these high frequencies within new technologies do not travel through objects as well as the lower frequencies do. In the past, propagation models for indoor wireless communications have not been needed and when used often rely on measurements that are specific to one environment. Hayley developed a mathematical model from Maxwell’s equations to predict the strength of propagation that can be used to optimise the source location. The model accounted for variation in the environment and is therefore relevant outside of one specific location, unlike most of the current models.
