Wireless communication is one of the most demanding applications for the telecommunications equipment designer. The mobile radio channel defines fundamental limitations on the performance of wireless communications systems. In this paper is presented mobile radio channel situated in different environments – rural and urban. Some of the most important factors are multipath propagation and shadow...

Chirped fiber Bragg gratings are used as low-loss, dispersion compensation modules for telecommunications applications. Here we use them to make an optical processor that compresses the bandwidth of electronic signals before digitization by an analog-to-digital converter. ©2007 Optical Society of America OCIS codes: (230.0250) Optoelectronics, (060.2360) Fiber optics and optical communications ...

Over the past decades, construction firms have been using several off-the-shelf telecommunication tools and techniques to provide the communication means necessary to their mobile personnel on the jobsite. It is obvious that two-way radio transceivers such as walkie-talkie were the de facto standard adopted within the industry at first sight and for many years for very good reasons i.e. inexpen...

 The paper presents a multimedia interactive course for teaching the operation of communications and audiovisual equipment. The objectives of the course are the following: providing a tool for undergraduate students which enables the self-learning of the equipment basis and operation, helping the students to get used to the laboratory equipment and trying to improve their understanding of the ...

Telecommunications has had a powerful impact on development in rural areas of Peru and Indonesia. The AID Rural Satellite Pro­ gram demonstrated new ways of providing telephone service and transformed the telephonce into an educational tool through the addition of simple audioconferencing equipment. INTRODUCTION The tremendous growthi in worldwide telecommunications services in the last few dec...

Telecommunications is shifting from anytime, anywhere to anytime, anywhere, any way, any speed, whatever. This requires a revolution in flexibility by going from today’s pre-defined networks and services to a new user-centric software-based creation of wireless communications and services. This creation of wireless communications and services on demand requires a new paradigm in network design ...
