3 Mobile Network

3 is the UK 's leading mobile media company offering a convergence of communications, entertainment and information .

Setting the 3G agenda - the market leader in 3G

3 are at a significant moment in the history of communications and media. They have created a different type of business by defining a new category which fuses together information, communication and entertainment in to a single mobile device.

3 is the largest 3G network in the UK and Europe

The 3 network is available across eight countries and has over 11 million customers. In the UK alone, 3 acquired 3.5million 3G customers after 32 months of operations - that's more than the other UK mobile operators combined.

In 2003, 3 launched the UK 's first video mobile network to bring new and better services to the mobile media market. Given 3G was a new technology, 3 undertook one of the fastest network rollouts in UK history and met their license regulatory requirements three years ahead of schedule.

3 UK have a list of first to be proud of. They have created the mobile media world of Information, Communication and Entertainment and are the market leader in 3G.

* 3 launched the UK 's first live video mobile news and entertainment channel, "Today on 3".
* 3 was first to stream live TV over mobile in the UK (Grand National 2005).
* 3 launched the UK 's first "over-the-air" real-time multi-player gaming over mobile.
* 3 was the first to offer customers full-length music videos on mobile.
* 3 was first to launch Videomail (the video equivalent of voice mail).
* 3 was first to premiere music singles over mobile, ahead of traditional media(Robbie Williams' "Misunderstood" video and Natasha Bedingfield's "I Bruise Easily").
* 3 broadcast the world's first ever live streamed gig (artist: Rooster, Nov 2004)3 was the first network to sign music video agreements with the major labels.

3 was the first mobile operator to offer Barclays Football Premiership highlights on video mobile.

Impact of mobile phone usage

Like all high structures, cellular antenna masts creates a hazard to low flying aircraft. Towers over a certain height or towers that are closer to airports or heliports are normally required to have warning lights. There have been reports that warning lights on cellular masts, TV-towers and other high structures can attracting and also confusing the birds. US authorities estimate that millions of birds are killed near communication towers in the country …..

The Independent newspaper provided evidence for the theory that mobile phone masts are a major cause in the collapse of bee populations, with controlled experiments demonstrating a rapid and catastrophic effect on individual hives near masts.. The mobiles emittinig some kinds of radiation which are not god for human health and also not safe for our environment.. there are lot of problems are created by the this radiation… all these things want to be control immediately…

GSM cellular network

GSM is a cellular network, which means that mobile phones connect to it searching for cells. GSM networks can operate in four different frequency ranges. Most GSM networks are operates in the 900 MHz or 1800 MHz bands. Some countries in the Americas use the bands from 850 MHz and 1900 MHz because the 900 and 1800 MHz frequency bands were already allocated

The rarer 400 and 450 MHz frequency bands are assigned in some countries, where these frequencies were previously used for first-generation systems.

In the 900 MHz band there are two different frequency dand for both the uplink and the downlink,for the uplink frequency band is 890–915 MHz, and the downlink frequency band is 935–960 MHz.. Time division multiplexing is used in this to allow eight full-rate or sixteen half-rate speech channels per radio frequency channel. There are eight radio timeslots grouped that is called as TDMA frame. Half rate channels use alternate frames in the same timeslot.

The transmission power in the phone is limited to a maximum of 2 watts in GSM850/900 and 1 watt in GSM1800/1900. macro, micro, pico, femto and umbrella cells these are all the five different cell size in a GSM network. Indoor coverage is also effectively supported by GSM and may be achieved by using an indoor picocell base station,
Femtocells are cells are mainly designed for use in residential or small business environments and connect to the service provider’s network via a broadband internet connection.these are all the some of the points in the GSM

Bluetooth multiplayer games

Mobiles are connected through a wireless protocol known as Bluetooth using special hardware. The games are designed to communicate with each other through this protocol to split game information. The basic restriction is that both the users have to be within a limited distance to get connected. In this type of connection the game mode can only be one to one or two players extra like a peer to peer connection between two PCs.

Features of Mobile phone

There are significant questions as to who first invented the camera phone, as numerous other people acknowledged patents filed in the early 1990s for the device, including David M. Britz of AT&T Research in March of 1994 and Philippe Kahn, who claims to have first invented it in 1997. The camera phone now holds 85% of the mobile phone marketplace. Mobile phones often have features beyond transfer text messages and making voice calls, including Internet browsing, music (MP3) playback, memo recording, personal organizer functions, e-mail, instant messaging, built-in cameras and camcorders, ringtones, games, radio, Push-to-Talk (PTT), infrared and Bluetooth connectivity, call registers, ability to watch streaming video or download video for later viewing, video calling and serve as a wireless modem for a PC, and soon will also provide as a console of sorts to online games and other high quality games (e.g. Final Fantasy Agito).

Uses & Design of Supercomputer

Uses

Supercomputers are used for extremely calculation-intensive tasks such as weather forecasting, climate research (including research into global warming), molecular modeling (computing the structures and properties of chemical compounds, biological macromolecules, polymers, and crystals), physical simulations (such as simulation of airplanes in wind tunnels, simulation of the detonation of nuclear weapons, and research into nuclear fusion), cryptanalysis, and the like. Military and scientific agencies are important users.

Design

Supercomputers traditionally gained their speed over conventional computers through the use of inventive designs that allow them to perform many tasks in parallel, as well as complex detail engineering. They tend to be specialized for certain types of computation, generally numerical calculations, and perform poorly at more general computing tasks. Their memory hierarchy is very carefully designed to make certain the processor is kept fed with data and instructions at all times—in fact, much of the performance difference between slower computers and supercomputers is due to the memory hierarchy design and componentry. Their I/O systems have a propensity to be designed to support high bandwidth, with latency less of an issue, because supercomputers are not used for transaction processing.

As with all highly parallel systems, Amdahl's law applies, and supercomputer designs devote huge effort to eliminating software serialization, and using hardware to accelerate the remaining bottlenecks.

Earth science in Natural Science

Earth science (also known as geoscience, the geosciences or the Earth Sciences), is an all-embracing word for the sciences related to the planet Earth, including geology, geophysics, hydrology, meteorology, physical geography, oceanography, and soil science.

Although mining and precious stones have been human interests right through the history of civilization, their development into the sciences of economic geology and mineralogy did not occur until the 18th century. The learning of the earth, particularly palaeontology, blossomed in the 19th century and the growth of other disciplines like geophysics in the 20th century led to the development of the theory of plate tectonics in the 1960s, which has had a similar impact on the Earth sciences as the theory of evolution had on biology. Earth sciences nowadays are closely linked to climate research and the petroleum and mineral exploration industries.
