Wireless Timeline NCR, originally known as National Cash Register Company, wants to connect wireless cash registers and submits a request to the Institute of Electrical and Electronics Engineers (IEEE), which sets up a committee called "802.11" to help define a standard for wireless technology. Many of the first wireless devices were not compatible with similar devices built by other companies. Developing 1985 The FCC releases three segments of the unlicensed frequency spectrum to the public, at 90OMHZ, 2.4GHZ and 5GHZ. 1988 Wi Fi The 802.11 standard is established, using the 900MHZ band, CERTIFIED 1997 an industry standard helped customers avoid being locked in to a single vendor's devices. The term "Wi-Fi" becomes a registered trademark of the Wi-Fi Alliance, a global non-profit organization that promotes wireless technology and standardization, Wi-Fi refers to a wireless network product that conforms to one of the 802.11 standards. Contrary to popular belief, Wi-Fi does not stand for b Wi Fi TM WiF The 802.11b standard, using the 2.4 GHz band, is ratified by the IEEE. The 11b standard increased wireless speeds from 2 megabits per second (Mbps) to 11Mbps. 1999 Other names considered included "FlankSpeed" and "DragonFly." NEW Very first 11b Wi-Fi products hit the market. "wireless fidelity." ab(Wi 2000 The 802.11a standard is ratified, using the less-crowded 5GHZ band, increasing wireless speeds up to 54Mbps.

The word "Wi-Fi" is added to the 2005 Merriam-Webster English dictionary. The 802.11n standard is ratified, optimized at 5GHZ, although multi- channel technology lets it operate at 2.4GHZ as well. 2006 Wi Fin D-Link releases 802,11g and 802.11n wireless adapters and routers. 2009 The number of qglobal Wi-Fi hotspots exceeds 1 million with the help of Starbucks, which introduces free Wi-Fi at all of its company-operated U.S. Many of today's 11n routers allow simultaneous dual band communication, making them compatible on the 2.4 and 5GHZ bands, with combined speeds of up to 900Mbps. 2010 locations. 802.11ac draft 2.0 is announced, with initial speeds of up to 1750Mbps (1.71Gbps) and the possibility of reaching up to 6.93Gbps in the future. D-Link releases its first 802.lln wireless network camera, the 2012 DCS-930L. 2013 Expected ratification date of the 802.11ac standard, commonly known as "11AC," in the 5GHZ band. D-Link releases a full line of 802.1lac wireless adapters and routers. 2014 Devices That Use Wi-Fi computers - mainly laptops MP3 Computer peripherals such as printers, mice and keyboards video smartphones TVs household players games appliances systems Wi-Fi Availability Many airlines now offer Wi-Fi in the air for a fee.

The increasing use of electronic control modules in cars makes it likely that Wi-Fi will help share information about your car's health and performance between the vehicle's owner, mechanic and dealer. Wi-Fi Use Statistics As of 2013, one in ten people in the world use wireless technology. According to a 2011 study by the Pew Research Center, the cell phone is the most popularly-owned wireless product in the United States. 83% Cell Phone TODAY 2020 56% There are an estimated 10 billion wireless devices in use, outnumbering the world's population of 7 billion, It's estimated there will be 30 billion wireless devices in use Laptop among 8 billion humans, 44% MP3 Player 12% E-reader je 1.43 devices per person. ie 3.75 devices per person. 8% Tablet 802.11AC Statistics Devices using the 802.11ac standard will transfer data up to The 11AC standard operates in the 5GHZ band, providing the best performance with less interference. 3 times faster than 802.11n products. 11N 11AC For example, transferring an 1.5Gb episode of the TV drama "Mad Men" wirelessly from a storage device to a player would take about: 802.11b 802.11a/g 802.11n 802.11ac (11AC) 802.1 12 minutes, 48 seconds 2 minutes, 20 seconds 28.4 seconds 1.7 seconds 0.87 seconds So make yourself a nice snack, uncork a bottle of wine and pour aglass or two in the time you save using a faster connection.
