1. INTRODUCTION

Satellites have been used for years to provide communication network links. Historically, the use of satellites in the Internet can be divided into two generations. In the first generation, satellites were simply used to provide commodity links (e.g., T1) between countries. Internet Protocol (IP) routers were attached to the page link endpoints to use the links as single-hop alternatives to multiple terrestrial hops. Two characteristics marked these first-generation systems: they had l ....etc

1. INTRODUCTION
The demand for making air traveling more 'pleasant, secure and productive for passengers is one of the winning factors for airlines and aircraft industry. Current trends are towards high data rate communication services, in particular Internet applications. In an aeronautical scenario global coverage is essential for providing continuous service. Therefore satellite communication becomes indispensable, and together with the ever increasing data rate requirements of applications, aeronautical satellite communi ....etc

Terrestrial trunked radio (TETRA) is the modern digital private mobile radio (PMR) and public access mobile radio (PAMR) technology for police, ambulance, fire, transport and security services. It is use by utilities, the military, public access, fleet management, closed user groups, factory site services, mining, etc. In short, TETRA is digital radio.TETRA uses Time Division Multiple Access (TDMA) technology with four-user channels one radio carrier and 25 KHz spacing between carriers. A TETRA trunking facility provides a pooling of all radio ....etc

ABSTRACT
The search for a new, safe and stable renewable energy source led to the idea of building a power station in space which transmits electricity to Earth. The concept of Solar Power Satellites (SPS) was invented by Glaser in 1968.Research is still going on in this field and NASA is planning to implement one by 2040. SPS converts solar energy into microwaves and transmit it to a receiving antenna on Earth for conversion to electric power. The key technology needed to enable the future feasibility of SPS is Microwave P ....etc

TErrestrial Trunked RAdio (TETRA) standard was designed to meet some common requirements and objectives of the PMR and PAMR market alike. One of the last strong holds of analog technology in a digital world has been the area of trunked mobile radio. Although digital cellular technology has made great strides with broad support from a relatively large number of manufactures, digital trunked mobile radio systems for the Private Mobile Radio (PMR) and Public Access Mobile Radio (PAMR) market have lagged behind. Few manufacture curren ....etc

ABSTRACT
Digital radio broadcasting is a technique which gives listeners interference free reception of high quality sound, easy to use radio, and the potential for wider listening choice through many additional station and services. Current analogue FM radio broadcasting systems in VHF band cannot satisfy demands of future ,such as excellent sound quality, large number of stations and small portable receivers and no quality impairment due to multipath propagation. Digital audio technology has set technical qu ....etc

ABSTRACT
Todayâ„¢s global communications infrastructures of landlines, cellular towers, and satellites are inadequately equipped to support the increasing worldwide demand for faster, better, and less expensive service. At a time when conventional ground and satellite systems are facing increasing obstacles and spiraling costs, a low cost solution is being advocated.
This seminar focuses on airborne platforms- airships, planes, helicopters or some hybrid solutions which could operate at stratospheric altitudes for sign ....etc
