Introduction

Cellular Digital Packet Data (CDPD) systems offer what is currently one of the most advanced means of wireless data transmission technology. Generally used as a tool for business, CDPD holds promises for improving law enforcement communications and operations. As technologies improve, CDPD may represent a major step toward making our nation a wireless information society. While CDPD technology is more complex than most of us care to understand, its potential benefits are obvious even to technological novices.

In this so-call ....etc

With in today's Internet data is transported using wavelength division multiplexed (WDM) optical fiber transmission system that carry 32-80 wavelengths modulated at 2.5gb/s and 10gb/s per wavelength. Today's largest routers and electronic switching systems need to handle close to 1tb/s to redirect incoming data from deployed WDM links. Mean while next generation commercial systems will be capable of single fiber transmission supporting hundreds of wavelength at 10Gb/s and world experiments have demonstrated 10Tb/shutdown transmiss ....etc

The popularity and usefulness of the Internet seem to grow exponentially every day. As a result of this rapid growth, mobile users expect to access the Internet?s information resources and to communicate with other Internet users. However, providing efficient and reliable stream transmissions in mobile computing environments presents a significant obstacle to the development of mobile computing systems over the Internet.

This paper presents three approaches-known as Fast Retransmissions, Data Interceptions, and Packet Interceptions-that can ....etc

Space switch fabric architecture is shown in figure. The switch consists of N incoming and N out going fiber links, with n wavelengths running on each fiber link. The switch is slotted, and the length of the slot is such that an optical packet can be transmitted and propagated from an input port to an out put optical buffer.

The switch fabric consists of three parts; optical packet encoder, space switch, and optical packet buffer. The optical packet buffer works as follows. For each incoming fiber link, three is an optical demu ....etc

Wireless phone use is taking off around the world. Many of us would no longer know how to cope without our cell phones. Always being connected offers us flexibility in our lifestyles, makes us more productive in our jobs, and makes us feel more secure. So far, voice has been the primary wireless application. But with the Internet continuing to influence an increasing proportion of our daily lives, and more of our work being away from the office, it is inevitable that the demand for wireless data is going to ignite. Already, in those ....etc

The nature of the public network has changed. Demand for Internet Protocol (IP) data is growing at a compound annual rate of between 100% and 800%1, while voice demand remains stable. What was once a predominantly circuit switched network handling mainly circuit switched voice traffic has become a circuit-switched network handling mainly IP data. Because the nature of the traffic is not well matched to the underlying technology, this network is proving very costly to scale. User spending has not increased proportionally to the rat ....etc
