CHAPTER 1
INTRODUCTION

Communication links between space crafts is an important element of space infrastructure, particularly where such links allow a major reduction in the number of earth stations needed to service the system. An example of an inter orbit page link for relaying data from LEO space craft to ground is shown in the figure below

Free space optical communications is a line-of-sight (LOS) technology that transmits a modulated beam of visible or infrared light through the atmosphere for broadband communications. In a manner similar to fiber optical communications, free space optics uses a light emitting diode (LED) or laser (light amplification by stimulated emission of radiation) point source for data transmission. However, in free space optics, an energy beam is collimated and transmitted t ....etc

INTRODUCTION

With the rapid progress in telecommunications, more and more services are provided on the basis of broadband communications, such as video services and high-speed Internet. With worldwide fundamental construction of a backbone network based on optical fiber providing almost unlimited communications capability, the limited throughput of the subscriber loop becomes one of the most stringent bottlenecks.Compared to the capacity of the backbone network, which is measured by tens of ....etc

The Robot control using the wireless communication and the serial communication



Executive Summary
The NASA Robotics Alliance Cadets Program is being designed to be implemented at a
very low start-up cost, and to make this goal obtainable, the program is being developed
using low to no cost components from already developed, well-tested and robust
engineering testbeds.
In this project we are trying to establish both wireless communication between the mob ....etc

People waste many hours driving each day. Although unavoidable, this time can be very boring to motorists.Similar to people taking mass transit who often pass the time socializing with those around them, motorists could benefit from social interactions if they were given broader social opportunities. Unfortunately, existing Multiparty Voice Communication (MVC) systems do not scale to large numbersof users and do not provide adequate access controls. We present RoadSpeak, a scalable MVC system that allows motorists to automatica ....etc
