Wednesday 28 November 2018, 1.30PM to 3pm
Speaker(s): Dr Adnan Ahmad Cheema, Ulster University
We are living in the era where we all are connected through the internet to connect, share, and access knowledge or entertainment. However, with the assumption that infrastructure is available to keep us connected. In a situation of a disaster (e.g. earthquake, flood, and hurricane) this assumption is not valid, and we will need alternative solutions to connect users (people, objects, and their combinations). These solutions, in general, must support high data rates to entertain large number of users and have low latency for mission-critical or real-time tasks (e.g. remote surgery in a disaster).
The vision of new wireless technology, the 5G network (5GN), encapsulates many applications e.g. mobile broadband, connected health, and intelligent transportation. To entertain such a wide variety of applications, the 5GN is required to support high data rates, few Gbps, and latency to a fraction of a millisecond as expected by the research communities, telecom manufacturer, and standardization bodies. Due to the support of the high data rates and the low latency, the 5GN is a suitable candidate to provide a reliable and secure connectivity platform in a disaster. However, how a 5GN or existing networks can be functional without infrastructure during a disaster leads to find new innovative solutions.
Previously, consumer drones were used to monitor and record information by operators in applications like media coverage and site survey. The consumer drones are now getting much interest in research communities with the capability to offload network traffic in scenarios like a shopping centre, festivals, concerts and sports stadiums. However, most of the research work is limited to the theoretical aspect and still required validation from the experimental domain to improve and design new and more practical systems, particularly to overcome challenges in the situation of a disaster. To design a drone-based communication system, it is important to understand the radio propagation channel. This talk will provide an overview of the drone-based communication system, requirements and challenges particularly to conduct the radio propagation channel measurements and modelling.
Adnan Ahmad Cheema received his PhD degree in electronics engineering from the Durham University, UK, in 2015. He continued to work in Durham as a research associate on a project funded by OFCOM, UK, dealing with the 5G radio propagation channel measurements and modelling. Since 2017, he joined the Ulster University, UK, as a lecturer in electronics engineering.
His research interests include drone communications, radio propagation, and IoT particularly for applications in 5G, disaster management, and e-health.

The Department also runs a programme of Research Student Seminars given by PhD students in their 3rd year of study.
