The first stepping stone in migration path to third generation wireless mobile services (3G) is the General Packet Radio Services, GPRS, a packet-switched technology that delivers speeds of up to 115kbps. If GPRS is already in place, Enhanced Data rates for Global Evolution (EDGE) technology is most effective as the second stepping stone that gives a low impact migration. Only software upgrades and EDGE plug-in transceiver units are needed. The approach protects operators' investments by allowing them to reuse their existing network equipment a ....etc

If the accuracy of the work done by any gadget is precision, then the cost of manufacturing the gadget becomes directly proportional to it. This in turn decreases the end users affordability or adoptability to it.

In the coming decades, the quality of work will play the role in all the fields. Too considering the Medical field, the accuracy, time, precision, adoptability, user-friendly are all to be considered.

This parameters plays the most important to develop a gadget in Medical field. So these parameters measure the cost of the gadget de ....etc

Wideband Sigma Delta PLL Modulator

The proliferation of wireless products over past few years has been rapidly increasing. New wireless standards such as GPRS and HSCSD have brought new challenges to wireless transceiver design. One pivotal component of transceiver is frequency synthesizer.

Two major requirements in mobile applications are efficient utilization of frequency spectrum by narrowing the channel spacing and fast switching for high data rates. This can be achieved by using fractional- ....etc

Abstract
Conventional refrigerants are being phased out worldwide to avoid ozone layer depletion and global warming and natural refrigerants are fast gaining favour nowadays. Single stage and multistage refrigeration system fail to widen the gap between heat source and heat sink temperatures required in m ....etc
