In a recent study from ITU, ICT is responsible for 2.5% of the Global Greenhouse Gas emissions, and about 10% of these emissions come from mobile telecoms. In the past the wireless network operator configure their network with optimum power and seldom consider saving power, however this will change in the future. In this research, we are trying to reduce un-necessary power consuming as well as offering the same quality of services. LTE is the next generation mobile communication standard, The downlink for LTE and LTE-Advanced uses OFDMA technology to maximise spectrum efficiency as well as providing flexible resource allocation. The system performance in terms of throughput is limited by many factors including power level at base stations and interference from neighbouring cells. In this study, we proposed an adaptive antenna system for LTE that can be combined with cooperative interference management. The base station can dynamically change coverage pattern according to traffics. The results are improved throughput performance and energy efficiency.

This project was funded by Macao Science and Technology Development Fund. It aims to find new ways to protect the e-system from potential frauds and cyber-attacks. Different from traditional database matching based anti-virus and firewall techniques. We developed proactive approaches to protect e-Government.
