This article describes a novel, bespoke, and low-cost 28-GHz RF TX and RX front end
design that has been combined with a commercial Software-Defined Radio and Raspberry …

In this paper, a new path-loss model for electromagnetic wave in an indoor multipath
environment is proposed based on matching coefficient, polarization matching factor, and …

We consider the choice of a radio transceiver module for use in a wireless sensor network
aimed at wildlife monitoring. In this application, power consumption and communication …

We present a technique to use a Time Modulated Array as the transmitter in a 5.8 GHz
propagation channel sounder. The 5.8 GHz signal is first modulated with a pseudo random …

Wireless communication systems rely on the radio channel. The characteristics of each
channel define the limiting performance of the communications system, and so must be …

Currently the inability to monitor rhino and other endangered animal species in real time is
hindering the e ort to reduce poaching. This thesis proposes a multi-hop adhoc wireless …
