A light-hearted panel-discussion on 'Green Radio'
Wednesday 19 May 2010, 08:30–10:00 (The Auditorium)
Motivated by our global concern over climate change and environmental issues, each branch of industry, including the wireless communications industry is dedicated to reducing their environmental impact. Hence both the industrial and academic community embarked on developing power-efficient 'green' radio systems. This is a challenging issue, especially in the light of the ever-increasing throughput requirements, when we consider that since the 9.6 Kbit/sec GSM data channel's development we gradually progressed to rates in excess of 13 Mbit/s, which may be delivered by the HSPA system and the even higher rates are promised by the emerging LTE-Advanced system. This corresponds to a rate increase in excess of three orders of magnitude. At the same time - despite the substantial advances in transceiver design the required bit-energy has not been reduced by a similar factor. There are nonetheless interesting further avenues to pursue and this panel session will seek to provoke debate on what constitutes an efficient green radio system, hypothesizing that any transceiver, which increases the throughput linearly with the transmit power may be deemed a 'green' solution. Dear Colleague, do join us for an enlightening debate in Taipei!

MIMO vs CO-OPERATION
Wednesday 19 May 2010, 10:30–12:00 (The Auditorium)
At the time of writing the design of MIMO systems has reached a state of maturity and they have also found their way into numerous standardized systems. Their benefit is that they are capable of increasing the achievable system capacity by a factor, which is proportional to the number of transmit antennas, provided that the number of receive antennas is identical to that of the transmit antennas. The employment of multiple antennas for downlink transmissions from the BS is indeed feasible, but the handheld terminals have limited dimensions and hence it is challenging to accommodate multiple antenna elements for downlink reception or for uplink transmissions. Fortunately the recent advances in cooperative communications facilitate the creation of Virtual Antenna Arrays from the single-antenna aided mobile stations. Naturally, there are numerous related design-challenges, which will be discussed in this panel session.
