area network. These networks rely on electromagnetic airwaves to transmit and receive over a defined area‚ usually a few hundred feet. (Yahoo-wireless) In most cases‚ a wireless transmitter will be connected directly to a wired land network using Ethernet cables. Once the network feed has been connected to the transmitter‚ and a constant power supply is established‚ a steady stream of radio‚ or infrared waves with be produced (both are electromagnetic waves). The vast majority of wireless LAN systems

Communications have changed the way we live and the way we kill. In World War II the Royal Corps of Signals (founded in 1920) duty was to operate and repair all army communications equipment. The radio transmitters of WWII served their intended purpose well‚ of a low frequency a low frequency transmitter and receiver‚ but the biggest problem was the weight factor of the battery pack needed to power these devices. So to offset the weight problem engineers went to lighter shorter lasting battery which in turn

In 1876‚ Alexander Graham Bell invented the telephone. This invention was a small remodel of the first underwater telegraph. It has two parts: a transmitter and a receiver. The transmitter was composed of three parts: a drum-like device (a cylinder with a covered end)‚ a needle‚ and a battery. There was only one hole that one would speak into and listen out of. The telephone allows instant long-range communication
