The History & Future Of WiFi

THE HISTORY & FUTURE OF WIFI Learn how the next generation of WiFi solves your home network congestion challenges. Though the Internet as we know it didn't come into being until the 1990s – The story of WiFi starts decades earlier Origins of the Internet THE THEORISTS >1929 Nikola Tesla's "World Wireless System" "We shall be able to communicate with one another instantly ... see and hear one another as perfectly as though we were face to face ... And the instruments through which we shall ... a man will be able to carry in his vest pocket." 1935 Paul Otlet's "Mundaneum" "From a distance, everyone will be able to read text ... projected on an individual screen. In this way, everyone from his armchair will be able to contemplate creation, as a whole or in certain of its parts." 1945 vannevar Bush's "Memex" "Consider a future device .. in which an individual stores all his books, records, and communications.. mechanized so that it may be consulted with exceeding speed and flexibility ... an enlarged intimate supplement to his memory." FROM ARPANET TO INTERNET 1969 Advanced Research Projects Agency Network (ARPANET) First working prototype of the Internet Funded by the United States Department of Defense Allowed multiple computers to communicate on a network 1983 Transmission Control Protocol and Internet Protocol (TCP/IP) Created by DARPA scientists Vint Cerf and Bob Kahn Grew ARPANET from a single network into a "network of networks" Considered the birth of the modern Internet 1990 The World Wide Web www. Invented by computer scientist Tim Berners-Lee System of accessing online data using websites and hyperlinks Popularized the Internet among the public The History of WiFi UNEXPECTED BEGINNINGS 1941 Frequency-Hopping Spread-Spectrum (FHSS) Technology Created and patented by Hollywood actress Hedy Lamarr Skipped signals over multiple frequencies in a predetermined pattern Intended to guide torpedoes without being detected in WWII The importance of Lamarr's invention was not known until decades later – Today, FHSS is used in WiFi, Bluetooth, Zigbee, and more EARLY WIRELESS NETWORKS 1971 Additive Links Online Hawaii Area Network Developed by Norman Abramson at the University of Hawaii First network to use radio communications and random access protocols Allows computers to send transmissions as soon as data was available 1985 Industrial Scientific (ISM) Band Release FCC released 2.4 GHz frequencies for unlicensed use FC Prevented microwaves from interfering with FCC-control frequencies Sparked a new era of wireless communication using 2.4GHZ frequencies 1988 waveLAN Created by NCR & AT&T to connect cash register systems Wireless network operating at 2.4GHZ, with speeds of 1 to 2 Mbps Later licensed to independent manufacturers for other applications RAPID DEVELOPMENT 1993 AT&T installed 1st large scale wireless network at Carnegie Mellon 1997 First IEEE 802.11 Standard released, based on WaveLAN technology 1999 "Wi-Fi" Trademark claimed by trade Wi Fi ALLIANCE association the Wi-Fi Alliance Over the past two decades, WiFi speeds have grown 650x WiFi: The Need for Speed WiFi'S MAX THEORETICAL SPEED 802.11, 1997 2Mbps 802.11B, 1999|11Mbps 802.11A, 1999| 54Mbps 802.11G, 2003 54Mbps WiFi 4, 2009 600Mbps WiFi 5, 2013 7,000Mbps WiFi 6, 2019 10,000Mbps 2,500 5,000 7,500 10,000 Speed in Mbps 1999: (802.11B) PROBLEM: Up to 5x faster than Lower prices made this the definitive wireless tech Interference from other ISM band WaveLAN devices slowed internet speeds 1999: (802.11A) PROBLEM: Widely adopted by corporate workspaces due to faster speeds Signals were easily absorbed by solid objects, reducing range Reduced interference by switching to 5.8 GHz bandwidth 1999: (802.11G) PROBLEM: Just one older device could slow Offered same speed as WiFi 2, but at 2.4 GHz for compatibility Backward compatibility lowered the cost of upgrading to faster equipment down a whole network by 21% 2009: WiFi 4 (802.11N) PROBLEM: WiFi could only handle one Multiple Input Multiple Output (MIMO) signaling boosted data speed Dual band 2.4 and 5.8 GHz combined the device's signal at a time benefits of WiFi 2 & 3 Millions of loT devices are constantly sending small amounts of data, creating congestion that slows down the whole network through constant demand 2013: WiFi 5 (802.11AC) Multi-user MIMO Mesh Networks Up to 4 simultaneous streams to communicate with more devices Functions as one network with the same credentials Increased speed by reducing lag time in networks with many devices Offers faster 5.8GHZ WiFi are faster, to your entire house PROBLEM: In 2017, the typical American household had 5 connected devices – Even with a state-of-the-art, WiFi 5 router, that's enough to slow down the entire network Built for loT WiFi 6 (802.11AX) WiFi 6 splits each transmission to stream to multiple devices at the same time Preventing loT from slowing down your network Prolonging the battery life of your connected devices Increasing speeds up to 6 Gbps – 4.6x faster than WiFi 5 On a network with just one device, WiFi 6 isn't much faster – but unlike older routers, it isn't slowed down by heavy traffic 90% of Americans already have at least one smart home devices (72 Nest thermostat Phillips HUE smart Lighting SmartThings hub WiFi 6 creates organized, efficient networks that support higher traffic Communicating with more devices simultaneous Handling larger packets of data from each device Working with full backward compatibility By 2020, there will be 20 billion loT devices worldwide 2.6X the number of devices today More than Is your WiFi ready for the future of Internet?
