Third Generation Cell Phones

Technology adopters do not usually pay attention to technological standards and protocols of the devices they are using. They might be thrilled by the excitement the specific gadget arises. That might be contented by the services the device provides. That is why it is surprising how a buzz word, related to a technology generations, such as the mobile phone network technology, 3G phone, has become so common, and well understood.

For the ordinary consumer of mobile phones, and smart phones, it does not make any difference which generation of mobile phone they are using, as long as it provides them the excitement, and convenience of using it.

But still there are many others out there that merely use the new technology, without understanding the technological differences compared to former generations.

Anyway, what has made the 3G technology so common? Let us try to simply describe and understand the meaning of it. The third generation of mobile phone technology consists of a collection of international technical standards, defined by many international standard institutes. This includes Application services, wireless communication, mobile TV, video conferences, and more, all in their mobile environment.

The first generation of mobile phones emerged during the beginning of the 1980s. Then the second generation (also called GSM) appeared in the market, 10 years later the third generation mobile network launched during the 2000 decade.

So the third generation is just another stage in the cellular phone technology that converts the cell phone from a regular phone device into a fully functional device with wide range of services, most suited for roaming and mobility. A fourth generation is about to come, naturally.

The main difference between the various generations of the mobile cellular network is the data rate and the security they provide to the users. The improvement of these basic services paved the way to full internet access, video conferencing, mobile TV, Video on demand, music download, picture transactions, gaming and TV broadcasting. The internet web protocols that are used by the third generation mobile network (IP), keeps the user hooked to the internet at all times, making home desktop computers, and even laptops, to some extent, redundant.

No wonder that most of the cell phone manufacturers compete for market share, and fight for gaining the users attention, by flooding the market with most innovative technology of mobile sets, every couple of months. Vendors like Nokia, Blackberry, Sonny Ericsson, HTC, Samsung, and more, are all involved in this market and push it to its edges.

The success of the 3G technology and the wide adoption by common users pushed the cell phone vendors to include various services within the cell phone, making them smarter and smarter. Applications and services related to mobility, such as GPS, maps, setting direction, and so on made their way into the smart phones.

The tight competition and the vast applications available for the 3G cell phones made this technology a great success in the market, reduced costs, made it available to all people, all over the world, grown up, as well as kindergarten kids.

Sketching with superconductors: Breakthrough in controlling defects could lead to new generation of electronic devices

ScienceDaily (Aug. 22, 2011) — Reporting in the journal Nature Materials, researchers from the London Centre for Nanotechnology and the Physics Department of Sapienza University of Rome have discovered a technique to 'draw' superconducting shapes using an X-ray beam. This ability to create and control tiny superconducting structures has implications for a completely new generation of electronic devices.

Superconductivity is a special state where a material conducts electricity with no resistance, meaning absolutely zero energy is wasted.

The research group has shown that they can manipulate regions of high temperature superconductivity, in a particular material which combines oxygen, copper and a heavier, 'rare earth' element called lanthanum. Illuminating with X-rays causes a small scale re-arrangement of the oxygen atoms in the material, resulting in high temperature superconductivity, of the type originally discovered for such materials 25 years ago by IBM scientists. The X-ray beam is then used like a pen to draw shapes in two dimensions.

A well as being able to write superconductors with dimensions much smaller than the width of a human hair, the group is able to erase those structures by applying heat treatments. They now have the tools to write and erase with high precision, using just a few simple steps and without the chemicals ordinarily used in device fabrication. This ability to re-arrange the underlying structure of a material has wider applications to similar compounds containing metal atoms and oxygen, ranging from fuel cells to catalysts.

Prof. Aeppli, Director of the London Centre for Nanotechnology and the UCL investigator on the project, said: "Our validation of a one-step, chemical-free technique to generate superconductors opens up exciting new possibilities for electronic devices, particularly in re-writing superconducting logic circuits. Of profound importance is the key to solving the notorious 'travelling salesman problem', which underlies many of the world's great computational challenges. We want to create computers on demand to solve this problem, with applications from genetics to logistics. A discovery like this means a paradigm shift in computing technology is one step closer."

Prof Bianconi, the leader of the team from Sapienza, added: "It is amazing that in a few simple steps, we can now add superconducting 'intelligence' directly to a material consisting mainly of the common elements copper and oxygen."

The X-ray experiments were performed at the Elettra (Trieste) synchrotron radiation facility. The work is published in Nature Materials , 21 August 2011 (doi:1038/nmat3088) and follows on from previous discovery of fractal-like structures in superconductors (doi:10.1038/nature09260).
