e idea of the first cellular network was brainstormed in 1947. It was intended to be used for military purposes as a way of supplying troops with more advanced forms of communications. From 1947 till about 1979 several different forms of broadcasting technology emerged. The United States began to develop the AMPS (Advanced Mobile Phone Service) network‚ while European countries were developing their own forms of communication. 1.2 History of GSM Technology Europeans quickly realized the disadvantages

Advantages Advantages & Disadvantages of Electric CarsAdvantages ~ a safe way to convert fossil fuels into automotive power ~ more efficient than gas-powered vehicles because their fuel can be harnessed from any source of electricity‚ which is available in most homes and businesses ~ the electricity created by electric cars is created by the burning of fossil fuels at power plants‚ instead of in an internal-combustion engine which pollutes the air. ~ the only new system required

1. Introduction to Power Engineering 1.1 Power System Functions The traditional power system is arranged as a hierarchy. Generators feed into a high voltage transmission system that facilitates bulk transfers of power over large distances. Connected to the transmission system are medium voltage distribution networks that take power from grid supply points and deliver it to the customers who are supplied a low voltage. For a lot of its history‚ the electricity supply industry has operated as
