WARC embraces PCN

IEEE Communications Magazine, 1992
A compromise reached at the 1992 World Administrative Radio Conference (WARC-92) concerning the international frequency allocations for personal communications systems (PCSs) is reviewed. The PCS debate at the WARC-92 resulted in the collision of two nearly polar views: that of the Europeans, whose advocacy of PCS techniques was limitless; and that of ...

PCN: the probabilistic convergent network

Proceedings of ICNN'95 - International Conference on Neural Networks, 2002
A new architecture for networks constructed from RAM-based neurons is presented which, whilst retaining learning and generalisation properties possessed by existing RAM-based network architectures, allows for a regular treatment of specialisation and generalisation with the additional property of providing information regarding the relative probability

Satellite PCN—the ICO system

International Journal of Satellite Communications, 1999
The ICO system is designed to provide global access to telecommunication services via a constellation of satellites in Medium Earth Orbit (MEO) and a ground segment referred to as the ICONET. The system integrates with terrestrial networks to provide terrestrial cellular-like services.

A WDM-based PCN architecture

IEEE Transactions on Vehicular Technology, 2002
This paper proposes personal communication network (PCN) architecture based on wavelength-division multiplexing (WDM). By employing the broadcast nature of the WDM star couplers, the proposed architecture furnishes a very simple and fast hand off procedure.

PCN: son of cellular? The challenges of providing PCN service

IEEE Communications Magazine, 1991
The engineering and marketing problems posed by personal communications networks (PCNs) are examined. The characteristics common to all PCNs are identified, emphasizing their use of small-coverage cells (microcells). Trials undertaken by the Bell Atlantic telephone companies are discussed. >
