Abstract
High performance indoor wireless communication systems, including third/fourth generation mobile communication systems and WLAN technologies, can provide high bandwidth and user capacity to highly localised areas, which implies small cell sizes and a large number of base stations to provide the necessary coverage. As a result, severe co-channel interference from adjacent cells (external interference) can occur, which greatly limits the performance promised by these technologies.

In this seminar, a research programme investigating the performance of indoor wireless communications systems being undertaken at The University of Auckland will be described. The seminar will focus on (i) selection and deployment strategies for simple antennas (eg the directional patch) with regard to the influence of external interference; and (ii) the possibility of deploying structural shielding in interference mitigation.


Biography
Alex Wong was born in Hong Kong, China, in 1978. He received the Bachelor of Engineering degree in Electrical and Electronic Engineering from The University of Auckland, New Zealand, in 2001. He is currently working toward the PhD degree in Electrical and Electronic Engineering from the same university since 2001. He receives the University of Auckland Doctoral Scholarship from 2001. His supervisors are Dr Michael Neve and Assoc. Prof. Kevin Sowerby. His research interests in indoor wireless communication systems originates from the growing demand in portable personal communication devices, such as mobile phones and WLANs. This demand drives the development of antenna deployment strategies which can increase the capacity of indoor wireless systems at a minimal cost. Also, he has been involved in indoor radio channel characterisation and DS-CDMA system performance estimation.

Derek Lee was born in Hong Kong and has been living in New Zealand since 1996. In 2002, he received his bachelor degree in Electrical and Electronic Engineering from the University of Auckland, New Zealand. He is currently working towards a PhD in Electrical and Computer Engineering, also in the University of Auckland. He has research interests in wireless communication systems including indoor propagation modeling, multipath prediction and the impact of architectural modification on wireless system performance.
