CELLULAR TECHNOLOGY NUT-SHELL
June 24, 2011 :: Posted by - maureen :: Category - Department
Cellular Technology or Mobile Technology or Wireless Communication Technology is commonly associated with mobile phones. Generally used terms mobile, wireless and cellular represent cellular technology. These terms are not same. Mobile & wireless are the terms of past. Today the technology we use is cellular technology. We use cellular phone & cellular network. Cellular technology is called cellular because of its mechanism. Cellular system uses many base stations to divide a service area into multiple cells. Using a cellular device a user can communicate while traveling from one area to another. The cell of a mobile phone functions as sender and accepter. A cell accepts & transfer small packets of data through a built in antenna device to specific location with some frequency. This specific location is called channel. All mobile operators use radio spectrum in order to provider their services. Spectrum is a limited resource. Earlier, mobile operator companies used division of frequencies to enhance the capacity. However cellular technology allowed division of geographical areas (alternate of frequency) which is leading towards wide area coverage. Cellular network is a combination of clusters. A .. more» 


The Economics of Nuclear Power
Electricity Generation
Nuclear Technology can also be used to produce ELECTRICITY which is very important according to economical condition of a country. Nuclear plant can produce more electricity than thermal or hydro electric plant.
Isotope produced using Nuclear Technology is used in many chemical and pharma companies.
1)Nuclear power is cost competitive with other forms of electricity generation, except where there is direct access to low-cost fossil fuels.
2)Fuel costs for nuclear plants are a minor proportion of total generating costs, though capital costs are greater than those for coal-fired plants.
3)In assessing the cost competitiveness of nuclear energy, decommissioning and waste disposal costs are taken into account.
The relative costs of generating electricity from coal, gas and nuclear plants vary considerably depending on location. Coal is, and will probably remain, economically attractive in countries such as China, the USA and Australia with abundant and accessible domestic coal resources as long as carbon emissions are cost-free. Gas is also competitive for base-load power in many places, particularly using combined-cycle plants, though rising gas prices have removed much of the advantage.
Nuclear energy is, in many places,
