Introduction

As network technology advances and the networks become more complex, wireless technology will inevitably follow. A wireless technology is a technology in which use of wire for communicating between clients is eliminated. Radio and TV broadcasting to Mobile phone and Blue tooth are examples of wireless technologies. The technology of electromagnetic waves has been used in all of these applications.

Wireless technology was un-imaginable till Heinrich Rudolf Hertz in 1886-1888 demonstrated the transmission and reception of radio signals. Sinking of Titanic in 1914 made the authorities to regulate the rule and made it mandatory to have all the ships to shore radios manned 24 hrs. This give a boost to this radio industry and technology. This created a new era of radiotelegraphy and telephony. First communication only satellite Telstar was launched on 1960s and it made it possible to communicate to any part of world.

In telecommunications, wireless communication may be used to transfer information over very short distances (a few meters as in television remote control) or long distances (thousands or millions of kilometers for radio communications). The term is often shortened to "wireless". It encompasses various types of fixed, mobile, and portable two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of wireless technology include GPS units, garage door openers, wireless mice, keyboards and headsets (Bluetooth), satellite television, and cordless telephones.

Radio/ Cell Phones

FM and AM Radio is the first to use wireless technology commercially. This brings wireless technology to the common person.

Television

Another step ahead with wireless technology is Television broadcast. This brings wireless technology even closer. Virtually all of the TV signals received, today, are...
