EERT 2010 - 1st International Workshop on Energy Efficient and Reconfigurable Transceivers

collocated with MOBIMEDIA - 6th International Mobile Multimedia Communications Conference

6th - 8th September 2010 - Lisbon, Portugal


The beyond3G vision envisages higher data rates and multi standard radio interfaces to provide all users with a continuous seamless connection at any place, anytime and on any system. Therefore the large number of multimode devices coupled with the surge in power requirements for future emerging handsets raises significant challenges in terms of reducing the energy consumptions, and reducing the amount of electromagnetic radiations in order to minimize the global impact of CO2 emissions.
In fact, current state-of-the-art of multi-standard devices have high power requirements for maintaining two or more radio interfaces. It is envisaged that a dramatic increase in the energy consumptions of 4G devices will make active cooling a necessity. Indeed, from the manufacturer’s perspective, the issue of power consumptions is becoming a key concern since there is a continuously growing gap between the energy required by emerging radio systems and what can be actually achieved by: i) the evolutions on battery technology; ii) the progresses on scaling and circuit design; iii) the design of novel system level architectures; and iv) the development of novel thermal and cooling techniques.
Therefore, one of the biggest challenges for the future wireless systems is the need to limit the energy consumptions of battery-powered devices, with the aim to prolong their operational time and avoid active cooling. Without new approaches for energy saving, there is a significant threat that the 4G mobile users will be searching for power outlets rather than for network access, thus being restricted to stay in a single position and losing their mobile capabilities.
In typical mobile terminals for cellular systems up to half of the power consumptions come from communications-related functions, such as baseband processing, RF, and connectivity functions. Therefore any reduction in the power consumptions of all these functionalities will have a substantial impact on the battery lifetime.
The EERT workshop will bring scientists, engineers, manufacturers and service providers to exchange and share their experiences, new ideas, and research results surrounding all aspects on energy-efficient transceivers for handset and BSs of the future.

Title: On-body radio channel modelling for power efficient RF transceiver design



Body-centric wireless communications refer to human-self and human-to-human networking with the use of wearable and implantable wireless sensors. It is a subject area combining wireless body-area networks (WBANs), Wireless Sensor Networks (WSNs) and Wireless Personal Area Networks (WPANs). Body-centric wireless communications has abundant applications in personal healthcare, smart home, personal entertainment and identification systems, space exploration and military.
The human body is an uninviting and often hostile environment for a wireless signal. In general, antennas suffer from reduced efficiency due to electromagnetic absorption in human tissues, radiation pattern fragmentation and variations in impedance at the feed.
Typical geometries of wireless wearable and implantable devices, vary from millimetric to- centimetric sizes and, hence, compact yet efficient antennas need to be fully characterized and integrated with the RF transceiver. As well as size there are other significant challenges in the design of antennas for body-centric wireless communications.
The objective of this talk is to highlight current and emerging research in antennas and propagation for body-centric wireless communications, as well as applications of this technology.


Professor Yang Hao received the Ph.D. degree from the Centre for Communications Research (CCR) at the University of Bristol, U.K. in 1998. From 1998 to 2000, he was a postdoc research fellow at the School of Electrical and Electronic Engineering, University of Birmingham, U.K. In May 2000, he joined the Antenna Engineering Group, Queen Mary College, University of London, London, U.K. first as a lecturer and was promoted to Reader in 2005 and to Professor in 2007.
Professor Hao is active in a number of areas including computational electromagnetics, electromagnetic bandgap structures and microwave metamaterials, antennas and radio propagation for body centric wireless networks, active antennas for millimetre/submillimetre applications and photonic integrated antennas. His work on metamaterials and body-centric wireless communications has been reported in the Engineer(I), the Engineer (II), Electronics Times, Microwave Engineering and the IET E&T Magazine. He is a co-editor of book 'Anntennas and Radio Propagation for Body-Centric Wireless Communications' (Artech House, 2006). He has published over 200 technical papers (book chapters, Journal papers and conference publications) and served as an invited (ISAP07) and keynote speaker (ANTEM05), a conference organiser and session chair at many international conferences.
Professor Hao is an associate editor for IEEE Antennas and Wireless Propagation Letters, an associate editor and a guest editor for IEEE Transactions on Antennas and Propagation. He is a Senior Member of IEEE and also a member of Technical Advisory Panel of IET Antennas and Propagation Professional Network. He is elected as a Fellow of ERA Foundation in 2007.

Title: A comprehensive Quality of Service (QoS) Performance bench-marks for GSM and CDMA networks for all interfaces



Digital Mobile Telecommunication Services (DMTS) have been adopted universally, and developing countries that hitherto have no established Wireline Telephony have embraced DMTS as a means of achieving rapid coverage so as to improve their very low level of Teledensity. However, countries that rely heavily on wireless telephony are faced with new set of challenges in respect of poor Quality of Service (QoS) delivery. A number of these countries have been relying on bench-marks or Key Performance Indicators (KPIs) that have been drawn with Wireline services in mind and for which reason such KPIs have not been adequate as Standard levels for Wireless services even where they are met. In this paper a comprehensive set of KPIs are proposed for Wireless Voice and Data services that are applicable to GSM as well as CDMA systems. The proposed set of KPIs are to be measured using one of or a combination of three methods; Drive test, Monitoring from Network Operating Centres (NOCs), and Consumer Survey. The KPIs cover Billing-related, Wireless, Data as well as Network-related Technical Parameters. A list of succinct definitions of the KPIs is also provided as a guide. Monitoring Data on TCH and SDCCH Congestion level collected from the NOCs of some operators indicate that deviation from the bench-marks being proposed in this paper can lead to poor Quality Services and often complete lack of access. Relevance of each of the KPIs to consumer experience is highlighted.
