    Personal communications services (PCS) are anticipated to herald a new era in global telecommunications. In this article, a perspective of some experiences obtained in New Zealand is presented. The topics discussed include: operational considerations, planning aspects, reliability, propagation and environmental aspects. Present-day telecommunications services have been influenced by numerous commercial, regulatory, demographic, and geographic factors peculiar to New Zealand. However, many of the lessons learned have direct relevance to the global telecommunications scene. In particular, contributions already made by New Zealand telecommunications research groups have gained worldwide recognition. The activities of one such group-the Radio Systems Group at the University of Auckland-are also discussed View full abstract»

    The authors present the background and an approach of Asian-Pacific cooperation in research and development (R&D) of mobile radio or wireless personal communications (WPC). Due to the regional features of the Asian-Pacific countries (APC) such cooperation is needed. The huge size of the APC market as well as its high production potential should be taken into account when a global standard for WPC is to be established. This article shows a view of the future WPC in the APC and introduces the Asian-Pacific Wireless Forum (APWF), which is a venue for discussion of the Asian-Pacific standard for WPC, as a step toward establishing a global standard that should satisfy personal or regional requirements as well as universal transparency in WPC View full abstract»

    Personal communications services (PCS) is a set of capabilities that allows some combination of terminal mobility, personal mobility, and service profile management. In other words, PCS allows a person, by employing a unique personal number, to access telecommunications services anytime, anywhere, with the services controllable by the person himself or herself. PCS has been widely recognized as one of the most significant growth areas in telecommunications for the decade to come. This article summarizes the Directorate General of Telecommunications' (DGT) PCS development plan for Taiwan, Republic of China. Furthermore, PCS R&D activities in the Telecommunication Laboratories, a DGT research institute, are described in detail. Examples include the enhancement and evolution of cellular systems, intelligent networks for PCS, wireless access technology, field trials, propagation measurements and modeling, and RF technology View full abstract»

    The authors examine the time-division duplex (TDD) mode of code-division multiple access (CDMA) communications. The differences from frequency-division duplex (FDD) are shown, and the advantages of using a TDD system are discussed. The TDD mode facilitates the implementation of several functions in the areas of power control, RAKE combining, and selection diversity combining, which can reduce the complexity of mobile units and improve system capacity View full abstract»

    Korea Telecom (KT), Korea's main telephone operator, is planning to launch PCS service in 1998, and is developing PCS systems with local manufacturers. This article describes KT's PCS marketing strategies, PCS network implementation directions, and the current status of system developments. In early 1996, prototypes of each network element were completed, which was followed by testing and system integration. The PCS will not only open up a new market for KT; it will be a major revenue source. This KT-PCS will also be the basis for the next generation of wireless communications in the 2000s View full abstract»

  • Wireless personal communications in Hong Kong: a university perspective

    The position of Hong Kong as a financial and commercial center of southeast Asia depends critically on telecommunications. A well-developed telecommunication infrastructure is in place providing high-quality services for both wireline and wireless communications. Hong Kong's application of wireless communicators is among the most active in the world. This has been encouraged by several factors, including the inconvenience of face-to-face communications for people on the move in a densely populated city, the relatively low cost of using wireless communications, the proactive attitude of regulators to adopting new technologies, a population that is not afraid of using new technologies to gain convenience, and strong competition among service providers. The Hong Kong Office of the Telecommunications Authority has awarded licenses for the new PCS-related services, and the government is also increasing funding support for research activities. In this article, the authors first outline Hong Kong's current regulatory and service status in wireless communications and the plan for opening up new PCS. The rest of the article focuses on the research effort in a new university, including development of receivers View full abstract»
