The third generation of mobile cellular systems are intended to unify the diverse systems we see today into a seamless radio infrastructure capable of offering a wide range of services in different radio environments, with the quality we
have come to expect from wire line communication networks. Since the mid-80's, studies on 3G systems have been carried out within the International Telecommunication Union (ITU), where it was called Future Public Land Mobile Telecommunication Systems (FPLMTS), lately renamed International Mobile Telecommunicat ....etc

Introduction

Pick up any newspaper today and it is a safe bet that you will find an article somewhere relating to mobile communications. If it is not in the technology section it will almost certainly be in the business section and relate to the increasing share prices of operators or equipment manufacturers, or acquisitions and take-overs thereof. Such is the pervasiveness of mobile communications that it is affecting virtually everyoneâ„¢s life and has become a major political topic and a significant contributor t ....etc

One of the major issues in the networking industry today is tremendous demand for more and more bandwidth. However, with the development of optical networks and the use of Dense Wavelength Division Multiplexing (DWDM) technology, a new and probably, a very crucial milestone is being reached in network evolution. The existing SONET/SDH network architecture is best suited for voice traffic rather than today's high-speed data traffic. To upgrade the system to handle this kind of traffic is very expensive and hence the need for the development of ....etc

Final Report on
Dual-Tone Multiple Frequency (DTMF) Detector Implementation
Presented By:
Giiner Arslan
for EE382C Embedded Software Systems
Abstract
Dual-tone Multi-frequency (DTMF) signals are used in touch-tone telephones as well as many other areas such as interactive control, telephone banking, and pager system. As analog telephone lines are converted to digital, researchers became interested in digital DTMF detectors.
There are many digital DTMF detecting algorithms, but most of them do not comply wit ....etc

Introducing DWDM
The following discussion provides some background on why dense wavelength division multiplexing (DWDM) is an important innovation in optical networks and what benefits it can provide. We begin with a high-level view of the segments of the global network and the economic forces driving the revolution in fiber optic networks. We then examine the differences between traditional time-division multiplexing (TDM) and wavelength division multiplexing (WDM). Finally, we explore the advantages of this new technology. ....etc

ABSTRACT
Third generation is the generic term used for the next generation of mobile communications systems. 3G will provide enhanced services to those - such as voice, text and data - predominantly available today.
Video on demand, high speed multimedia and mobile Internet access are just a few of the possibilities for users in the future. 3G Services will expand the possibilities of information and communication.
UMTS is a part of the International Telecommunications Union's (ITU's) 'IMT ....etc

ABSTRACT
Video-conferencing is simply a method for people in two or more locations to not only talk with one another, but to see each other and exchange information. Desktop video-conferencing (DVC) is an emerging technology of video-conferencing that uses a standard personal computer which has been enhanced with special video processing capabilities and a small camera. This technology is employed by a broad spectrum of users to facilitate cost effective communication with key individuals or groups regardless of their geographic location. Ide ....etc

ABSTRACT
The H.323 standard provides a foundation for audio, video, and data communications across IP-based networks, including the Internet. By complying to H.323, multimedia products and applications from multiple vendors can interoperate, allowing users to communicate without concern for compatibility. H.323 is an umbrella recommendation from the International Telecommunications Union (ITU) that sets standards for multimedia communications over Local Area Networks (LANs) that do not provide a guaranteed Quality ....etc
