We report on a low-cost V-band wireless transceiver with no use of any local oscillator in the receiver block using a self-heterodyne architecture. V-band millimeter-wave monolithic IC (MMIC) modules were developed to demonstrate the wireless transceiver using coplanar waveguide (CPW) and GaAs PHEMT technologies. The MMIC modules such as the MMIC low noise amplifier (LNA), medium power amplifier (MPA) and the up/down-mixer were installed in the transceiver system. To interface the MMIC chips with the component modules for the transceiver system, CPW-to-waveguide fin-line transition modules of WR-15 type were designed and fabricated. The fabricated LNA modules showed a $S_{21}$ gain of 8.4 dB and a noise figure of 5.6 dB at 58 GHz. The MPA modules exhibited a gain of 6.9 dB and a $P_{1dB}$ of 5.4 dBm at 58 GHz. The conversion losses of the up-mixer and the down-mixer module were 14.3 dB at a LO power of 15 dBm, and 19.7 dB at a LO power of 0 dBm, respectively. From the measurement of V-band wireless transceiver, a conversion gain of 0.2 dB and a $P_{1dB}$ of 5.2 dBm were obtained in the transmitter block. The receiver block showed a conversion gain of 2.1 dB and a $P_{1dB}$ of -18.6 dBm. The wireless transceiver system demonstrated a successful data transfer within a distance of 5 meters.

This paper describes the evolutionary trajectory of the missions of public research institutes(PRIs) in Korea since 1960s and analyses the newly highlighted role of PRIs as the facilitators of regional innovation system, with questionnaire surveys and the case study of Gwangju Institute of Science and Technology(GIST). PRIs have played important roles in Korean rapid economic development by introducing and improving foreign high-technologies in 1970s and 1980s and by creating new advanced high-technologies in 1990s. In recent years, the functions as regional technology innovators have been considered important as regional innovation system has come to the center of discussion. According to the result of this study, Korean PRIs have recognized their roles relevant to regional innovation, such as developing the technologies of regional strategic industries and awakening regional innovative actors to a sense of research. Regardless of the functions as industrial technology suppliers, however, the bilateral networks between PRIs and regional industries are not revealed strong, whereas those with universities and other research institutes are relatively strong. In addition, the research cooperation of PRIs with regional innovative actors are different by where they are located. The case of GIST shows how a regional PRI operates, commercializes its academic achievement and encourages the regional transfer of the achievement systematically. Finally, this study draws some policy implications on developing regional PRIs.

Purpose - Several domestic telecommunication companies have made a considerable effort to continuously grow and survive, and they have strived to thrive in the midst of mature market competition. To overcome this challenging situation and to grow continuously, while still meeting customer needs that are becoming more diverse and complicated with the passage of time, extensive support for internal marketing is essential. Without such internal support, companies face serious limitations and market roadblocks. The communication industry is a high-level service industry and a basic communications industry characteristic is its significant dependence on the employees delivering the services. Therefore, entrepreneurs in the information/communications industry, as well as existing competitors, should look to satisfy external customers through critical investment in internal customers (employees). Therefore, it is important for research to examine how internal factors influence technology innovation and service quality, which are the key drivers for companies that are seeking leading market positions. Research design, data, and methodology - The purpose of this study is to analyze the relationship of technology innovation and perceived service quality with the internal marketing factors in the communication industry and to offer suitable and effective internal marketing suggestions.
