The beginning
the german phisic rudolf hertz performed the first transmition without cables with electromagnetic waves throught an oscillator and a resonator. -
A new communication
Six years later, the radio waves were a tool of communication, a little before, an industry essential for the world of the marketing and the communications. -
The first wireless communication
Marconi established the first wireless communication by The channel of the stain. -
New messages
In 1907 the first messages that crossed the Atlantic were transmitted. -
ALOHA
In 1971, the university of Hawaii made the first commutation of packages through a network of radio communication called ALOHA, this were the first wireless local network (WLAN) and were formed by 7 computers located in different islands. -
the 80s
In 1985, the technology called 802.11 was made available for use due to a U.S. Federal Communication Commission ruling, which released the three bands of the radio spectrum now used for nearly all wireless communication. -
The 90s
When the IEEE was formed in 1990, they chose Vic Hayes, also popularly known as the "Father of Wi-Fi," as its chairman. For the next ten years, Hayes helped direct the development of new wireless protocols as well as market the technology worldwide. -
2000s
The adaptation of 802.11n, sometimes called Wireless-N, saw a huge leap forward in the technology. With the ability to transfer data up to 300 Mbps and the incorporation of multiple wireless signals and antennas (called MIMO technology) -
Present day
The latest technology, 802.11ac, proved to be another huge leap forward. With the advancements in dual-band technology, data can now be transmitted across multiple signals and bandwidths allowing for maximum transmission rates of 1300 Mbps with extended ranges and nearly uninterrupted transmission. -
