ABSTRACT
After years of research and development, radio frequency light sources are just now becoming a mainstream lighting option. RF light sources follow the same principles of converting electrical power into visible radiation as conventional gas discharge lamps. The fundamental difference between RF lamps is that RF lamps operate without electrodes .
There are three practical ways to energize RF light sources, though there are more ways to create RF plasmas. These three ways correspond to differen ....etc

ABSTRACT
RFID is an area of automatic identification that has quietly been gaining momentum in recent years and is now being seen as a radical means of enhancing data handling processes, complimentary in many ways to other data capture technologies such as barcoding. The object of any RFID system is to carry data in suitable transponders, generally known as tags, and to retrieve data, by machine-readable means, at a suitable time and place. Data within a tag may provide identification for an ite ....etc

Each mobile uses a separate, temporary radio channel to talk to the cell site. The cell site talks to many mobiles at once, using one channel per mobile. Channels use a pair of frequencies for communication. One for transmitting from the cell site, the forward link, and one frequency for the cell site to receive calls from the users, the reverse link. Communication between mobile units can be either half-duplex or full-duplex. In case of half-duplex, transmit and receive communications between the mobile units are not at the same time, i.e. ta ....etc

1. INTRODUCTION

GLOBAL Positioning System (GPS) receivers for the consumer market require solutions that are compact, cheap, and low power. Manufacturers of cellular telephones, portable computers, watches, and other mobile devices are looking for ways to embed GPS into their products. Thus, there is a strong motivation to provide highly integrated solutions at the lowest possible power consumption. GPS radios consist of a front-end and a digital baseband section incorporating a digital processor. While for the baseband processor, cost-reduc ....etc

Whatâ„¢s the Software Defined Radio

Software Defined Radio (SDR) refers to the technology wherein software

modules running on a generic hardware platform consisting of DSPs and

general purpose microprocessors are used to implement radio functions

such as generation of transmitted signal (modulation) at transmitter

and tuning/detection of received radio signal (demodulation) at

receiver.¦a radio that includes a transmitter in
which the operationg parameters of the

ABSTRACT
Satellites are one of the greatest achievements of mankind. They have been used for various applications like communication, military application, weather forecasting and so on. They play a big role in the case of television channels and other entertainment networks. One of the latest applications of satellites is the satellite radio.

Satellite radio is a subscriber based radio service that broadcast directly from satellites. It is an advanced form of mobile radio service where one can rec ....etc

Todayâ„¢s mobile professionals need to stay in regular contact with important sources of information such as the Internet, email, corporate networks and remote databases. As demand for Wide Area Networking (WAN) connectivity continues to grow, users and organizations are seeking ways to make it more efficient and productive. One of the most promising new technologies for this purpose is General Packet Radio Service (GPRS). GPRS is a packet-switching data network that is overlaid on the existing cellular voice network, using the same radio ....etc
