Running Head : Elements of Wireless TechnologyName : Course : University : Tutor : Date : Elements of Wireless Technology Introduction To clearly understand this important aspect of what could perhaps be the key to contemporary modernization , it is essential to define the various terms that are commonly used . What is "wireless ? One may ask wireless is broad term that refers to any form of electrical or electronic operation that is accomplished without a physical or what is termed as "hard-wired " connection (Carl J . Weisman (1999 ) Modern technology has advanced to such levels where the use of the "hard wire " is becoming an obsolete necessity . Through wireless communication , information transfer over a given distance is carried out efficiently without the necessary use of electrical wires or "conductors . These distances vary from short to some time extremely long distance (Carl J . Weisman (1999 ) Therefore the term "wireless " seeks to describe communications where instead of physical wire , electromagnetic waves are utilized to carry a signal through a path of communication . Wireless technologies allow long- range communications that would be practically impossible to implement using wires (Steven Kellogg (1999 ) Wireless technology as a term is generally used in the telecommunication to broadly describe the entire range of telecommunications systems . Such telecommunication systems include radio transmitters and receivers , computer networks , remote controls and other important components . These systems utilize various forms of energy (for example visible light , radio frequency (RF , laser light , acoustic energy an so on ) in the transfer of information "wirelessly (Steven Kellogg (1999 ) There are various common examples of equipment that utilize the wireless technology which include . Satellite television , which enables users or viewers to select from a range of channels from any location . Cordless computer peripherals , which enable such components as the mouse , keyboards and printers to be operated without any form of physical connectivity . Global positioning systems (GPS ) this facility enables car /truck driver 's...
