WiFi Historical Background

In 1985, Guglielmo Marconi opened the way for modern wireless communications by transmitting the three-dot Morse Code for the letter “S” over a distance of 3 km using electromagnetic waves. From this beginning, wireless communication, was developed into a key element of the modern society.

v This has not been so developed over the years when wired communication flourished.

v Not until in 1971 that the University of Hawaii pioneered the way to wireless networking in their development of ALOHA NET. This network was originally designed to solve the university’s dilemma of being able to transmit data to and from their four different sites scattered across the Hawaiian Islands.

Wireless Fidelity

v Wireless Fidelity underwent its development in the mid 1990’s, being developed by research groups at the Institute of Electrical and Electronic Engineers.

v Throughout the course of history, wireless networks have evolved from the simple wireless LAN based ALOHANET into the more sophisticated Wireless Fidelity concept, developed by the Institute of Electrical and Electronic Engineers (IEEE).

Shipping was a major early client for wireless telegraphy and wireless was standard for shipping by the time the Titanic issued its radio distress calls in 1912. Early on, it was quickly recognized that international coordination was required for wireless communication to be effective. This coordination involved two features.

v The potential for interference in radio transmissions meant that at least local coordination was needed to avoid the transmission of conflicting signals.

v With spectrum to be used for international communications and areas such as maritime safety and navigation, coordination was necessary between countries to guarantee consistency in approach to these services.

This drove government intervention to ensure the coordinated allocation of radio spectrum.

Since studying wireless communication is too broad, the researcher limits its scope into wireless networking more specifically the presently widely used “Wi-Fi”.

Wi-Fi was launched by Wi-Fi Alliance in 1985 it was the time when it was not utilized as commercially but have been just set to certain organizations for testing functions. Yet merely five years ago wireless networking was a niche. How did Wi-Fi get started, and become so successful, in depths of a downturn? Wi-Fi seems remarkable when you look at its provenance: it was, in effect, spawned by an American government agency from an area of radio spectrum

widely referred to as “the garbage bands”. Technology entrepreneurs generally

prefer governments to stay out of their way: funding basic research, perhaps, and

then buying finished products when they emerge on the market. But in the case of

Wi-Fi, the government seems actively to have guided innovation.
