The most important development in the computer communications industry in the 1990s is the evolution of the integrated services digital network (ISDN) and broadband ISDN (B-ISDN). The ISDN and B-ISDN have had a dramatic impact on the planning and deployment of intelligent digital networks providing integrated services for voice, data and video. Further, the work on the ISDN and B-ISDN standards has led to the development of two major new networking technologies; frame relay and asynchronous transfer mode (ATM).

UWB is a wireless technology that transmits binary data”the 0s
and 1s that are the digital building blocks of modern information
systems. It uses low-energy and extremely short duration (in the order
of pico seconds) impulses or bursts of RF (radio frequency) energy over
a wide spectrum of frequencies, to transmit data over short to medium
distances, say about 15”100 m. It doesn™t use carrier wave
to transmit data.

Abstract
This seminar discusses inter-technology mobility functionality being defined for emerging broadband wireless technologies and explains how this new functionality will add value to operatorâ„¢s networks. It explains the difference between various types of inter-technology mobility and then explores how LTE exploits inter-technology mobility to support a variety of access technolo- gies including 3GPP legacy technologies as well as EVDO, WiFi and WiMAX. This paper also provides examples illustrating how to use ....etc

Abstract
The LTE (Long Term Evolution) technologies definedby 3GPP is the last step toward the 4th generation (4G) ofradio technologies designed to increase the capacity and speed ofmobile telephone networks. Mobility management for supportingseamless handover is the key issue for the next generationwireless communication networks. The evolved packet core (EPC)standard adopts the proxy mobile IPv6 protocol to provide themobility mechanisms. However, the PMIPv6 still suffers the highhandoff delay and the large packet lost. Our protocol ....etc

INTRODUCTION

The average person has a small home, but a huge appetite for entertainment. All of us would want to zap video images from digital camcorders to our hard drives without tripping over the cables that connect them. As home entertainment systems become more sophisticated, u will have flat panel displays. You could hang them like paintings on your wall¦..Now who would want cables to dangle from those beauties?

So you think - big deal¦. We have Bluetooth and 802.11 wireless technologies to solve this problem. They do a dece ....etc

SIM Toolkit Modifications for 3GPP

3GPP TSG-T3 (USIM) Meeting #10
Austin, USA, 2 - 5 November, 1999
Tdoc T3-99346
Source: Nokia


General
The SIM toolkit has been designed for a single application environent. As a result of this the SAT can be started at the initial power up of the card. In 3GPP the multiapplication environment has to be taken into account in such a way that the USAT is not activated until a specific application has been selected. Further more there are SAT commands that are more card related than application ....etc

Power line communications (PLC) or Broadband over Power Lines (BPL) allows transmission of data over power lines.Power line communications uses the RF signal sent over medium and low voltage AC power lines to allow end users to connect to the Internet. The RF signal is modulated with digital information that is converted by an interface in the home or small business into Ethernet compatible data.

To gain a good understanding of how PLC Works an excellent understanding of the Power Grid is required. Unlike telephony and it's ass ....etc

Abstract

An integrated photonic microwave bandpass filter has been demonstrated incorporating a coherently coupled microring resonator in low-loss polymers. The resonator was designed to have an extremely small bandwidth so that it could be used to selectively pass the optical signal carrying the microwave signal to attain efficient bandpass filtering. The demonstrated device may feature compact size, simple structure, stable operation, possible tuning via the thermooptic effect, and furthermore flexible integration with other electrical/opt ....etc
