Digital Enhanced Cordless Telecommunications(DECT) can carry both voice and data. The DECTLAN project at Centre for Wireless Communications (CWC) aims to develop a wireless LAN system based on the DECT standard. In phase I, the DECTLAN system supports a single duplex DECT bearer and an effective data rate of 24 kbps with no mobility support. In phase II of the project, the system will support 6...

The fiber optics and optoelectronics industry has experienced a tremendous amount of innovation over the past four decades. Initially conceived for medical endoscopic applications, optical fibers were considered in the mid-1960s as an adequate technology for telecommunications applications. Since then, light wave communications systems have become the preferred and standard method to transmit v...

Parvan 2, 300223 Timisoara, Romania, [email protected] Abstract – This paper presents a novel method of eyes detection on color images of human faces, by using cellular neural networks. Based only on first order interconnections it is easily hard implementable. Experiments made on a standard database show that t...

The optimal design of input prices is analyzed in a simple setting where the regulator has limited knowledge of efficient production costs. Under some conditions, input prices are optimally set equal to expected efficient production costs, as under the Federal Communications Commission’s TELRIC pricing policy in the U.S. telecommunications industry. More generally, input prices optimally reflec...

In recent years telecommunications services in remote Australia have received considerable attention, with services for indigenous desert communities a key focus. This project, known as Desert Interactive Remote Television (DIRT), uses existing community rebroadcast TV infrastructure to provide low cost multimedia messaging services for remote desert communities. The system architecture, key ap...

FIPA has provided a standardised model for implementing interoperable agent systems that may prove the basis for new solutions to the problem of managing the growing complexity of the telecommunications infrastructure. However, the ability of agents to operate in the telecommunications domain would be greatly enhanced if the FIPA architecture was refined to deal with the standardised SS.7 commu...

Nowadays, Wireless communications are pervasive in modern society and leverage the fast growth of new services, this trend is likely to increase for foreseeable future. Nonetheless, wireless networks have become more complex because number different services that must support. Therefore, research critical than ever ensure successful deployment exploitation related services. This special issue i...

In this paper we apply a simple two-period model of investment to examine how consideration of the real options associated with investment decisions might be expected to affect the cost of capital for telecommunications infrastructure firms in light of the tumultuous changes associated with the emergence of the Internet. Because investments in new telecommunications facilities also may provide ...
