WRC-95 and personal communication systems

摘要

The personal communication system (PCS) is seen as a major gap or discontinuity in telecommunication services and technologies. The International Telecommunication Union (ITU) has already undertaken the task of defining Future Public Land Mobile Telecommunications Systems (FPLMTS) which will mostly cover standards for PCS. The ITU World Radio Conferences address frequency allocation and related technical and regulatory aspects. The efforts in different ITU fora are important not only to approve various technical and regulatory provisions to enable implementation of mobile and PCS to meet the immediate market requirements but also to ensure adequate flexibility in the systems to meet future technical and operational requirements including compatibility in multiple operator environments. Among the new technologies, non-GSO MSS satellite systems are designed to provide global personal communications by more efficient use of radio frequency spectrum and power and by also taking advantage of the characteristics of orbiting satellites. The WRC-95 conference concentrated on several frequency allocation and related issues pertaining to nonGSO mobile satellite services (MSS).
