Workshop 01
System-on-Chip/One-Chip Radio
Organizer: Tadao Nakagawa, NTT, Japan
Chair: Tadao Nakagawa, NTT, Japan
The demand for small, inexpensive radio modules is increasing. RF integrated circuits on Si, which are the key components of radio modules, have evolved remarkably in recent years. RF systems on a chip (SoC) that integrate RF, analog, and digital circuits have been developed to reduce occupied circuit area and off-chip discrete components that add to assembly and test costs. Today, the RF SoC is dominant in applications such as Bluetooth and wireless LAN, and many RF SoC devices have been developed in applications such as GPS, ETC, and GSM. Moreover, the demand for multi-band and multi-mode transceivers that can be used in various applications and that are able to connect to networks anytime, anywhere using the most suitable application among all available applications is increasing. RF SoC devices are indispensable in making multiband and multi-mode transceivers small and economical.

This workshop presents a review of the SoC developments in various applications and of the technical issues that must be overcome.

Workshop 02
Advanced MIMO Antenna Technologies
Organizer: Yoshihide Yamada, National Defense Academy, Japan
Chair: Yoshihide Yamada, National Defense Academy, Japan
High speed transmission through a limited frequency bandwidth is strongly demanded in such systems as wireless local area networks (LANs) and cellular networks. Multiple-Input MultipleOutput (MIMO) systems that have multiple antennas at both of the transmitter and receiver in multipath channel environments have attracted much attention for these years. When independent signals are transmitted from the different antennas and they are separated at the receiver side, transmission speed is increased by the number of the transmit antennas. Also, if the transmitter side has multipath channel state information, maximum throughput can be achieved by the eigen beamforming technique. In frequency selective multipath channels, the MIMO technique is employed together with orthogonal frequency division multiplexing (MIMO-OFDM). Other than the above spatial multiplexing technique, the MIMO system can achieve reliable wireless communications by the space ti me coding that is a combination of the MIMO system and the coding technique.

In this workshop, starting from overview of MIMO technologies, performance evaluation of MIMO systems in home and cellular environments will be presented. Furthermore, considerations on antenna configuration of MIMO systems will be given. The workshop will be useful for understanding of the latest MIMO technologies.

Workshop 03
Standardization of Measurement Methods for Microwave and Millimeter Wave Materials
Organizer: Osamu Hashimoto, Aoyama Gakuin Univ., Japan
Chair: Yoshinori Kogami, Utsunomiya Univ., Japan
Microwave and millimeter-wave technologies have been developed further and their applications have been spread widely in recent years. The standardization of these technologies which has been discussed in the International Electro-technical Commission is necessary for us to promote the international cooperation. The role of IEC, which attained the one hundredth anniversary of its existence, becomes still more important.

In this workshop, the activity of the standardization and its recent trend will be discussed at first. The actions on the standardization of the evaluation method for the microwave and millimeterwave materials, which have been investigated in the IEC domestic committees in Japan, will be introduced subsequently.

Emerging Technologies and Applications of RFID
Organizer: Jin Mitsugi, Keio Univ., Japan
Chair: Jin Mitsugi, Keio Univ., Japan
RFID (Radio Frequency Identification) has been gathering significant industrial interests. Contactless card type RFID has already widely adopted in commercial uses. Long range RFID and fusion of RFID and sensors/actuators are in the early stage of the industrial adoptions. The major technical difficulties for long range RFID resides in the fast and stable reading performance and the avoidance of interference among transmitters. The proper definition and evaluation of RFID wireless system needs to be exploited. Since the long range RFID and sensor RFID are still in their infancy, the technical requirements from industries need to be understood by the technology proponents. In this workshop, Emerging Technologies and Applications in RFID, accordingly, leading researches and expectations from industry on long range and sensor RFID technology are presented.

Millimeter and Terahertz Wave Applications
Organizer: Tadao Nagatsuma, NTT, Japan
Chair: Tadao Nagatsuma, NTT, Japan
Electromagnetic waves called "millimeter waves" (30GHz. 300GHz) and/or "terahertz waves" (100GHz.10THz) are considered to be major resources for mankind in the 21st century. These frequency bands cover interdisciplinary regions between radio waves and light waves, which are both bases of todays telecommunications technologies, i.e., wireless and fiber-optic communications. The exploration of such undeveloped frequencies has recently been accelerated with rapid evolutions of both electronic and photonic device/circuit technologies. This workshop will address an overview of the latest development in the millimeter and terahertz-wave devices and their applications to communications, sensors and measurements. The first part of the workshop will concentrate on millimeter-wave technologies, and in the second part, emerging terahertz device technologies and their promising applications will be presented.

While the demand for data communications over wireless links is rapidly growing, there is strong social interest in guarding personal information and official secrets. Wireless security is inevitable for microwave and RF systems to break through the worldwide market. This session explores span-new possibility of harmonizing two originally different technical topics: RF and security. You will find technical Hellenism between Maxwellian engineering and information theory in the three invited presentations.
