Wifi Full Name –

Wifi ka pura naam kya hai

wifi ka full name Wireless Fidelity.

WiFi ka aviskar kisane kiya –

WiFi Discover –

WiFi ka Discover ( Avisakr ) John O’Sullivan aur John Deane ne year 1991 me kiya tha.
History of WiFi –

WiFi ka Born (janm ) 1985 ko hua tha aur United State FCC ne jab ye alan kiya ki wireless Frequency 900 MHz , 2.4 aur 5.8 GHz ko koi bina License ke use kar sakte hai
Ye technology ka use gharo me Microwave, ka use kiya gaya jata tha, au rise khaskar Communication me koi bhi use nhi kiya hai, es band ka use karne ke liye FCC ne isko use karne ke layak banaya gaya.


Spread Spectrum Technology –

Ye technology ka license 1941 ko liya gaya hai, License lene ke liye George Antheil aur Actor Hedy Lamarr, ye technology the jiske medium se Single ko Multiple Frequency ke sath bheja tha, es badalaw ke sath kuch ho n ho magar us daur me es technology ke bad Wireless Singles me kabhi improvement najar aya .

Ye technology interference problems ko solve karne me safal nhi rhi thi, kyonki us waqt ke mobiles me pahle se hi Radio Install rahta hai, jiski wajah se Single ki Quality me kabhi asar padata hai.

Usi time ek aur technology ayi thi jo ki hai WLAN (Wireless Local Area Network ) jisme bahut sari technology kharab thi, jaise me WLAN ka koi Standard nhi tha, alag alag Company ki Devices ko jodne me kabhi problem ka samana karna pada.

1988 ke NCR Corporation ko ek wireless Cash  Register ki jarurat thi, esliye unhone victor Hayes aur Bruce Tuch ke madad ke sath unhone ne Institute of Electrical and Electionic Enigneer (IEEE) ko ek Standard banana ke gujaris kit hi, 1997 me Standard taiyar ho chukka hai, aur jiske naam kabhi attractive tha aur wo “802.11” 1997 me hi isko Publish kiya gaya tha.

802.11 Standard me DATA Transfer ki speed 2 Mbps thi, aur 1999 me 802.11a me lanch kiya gaya tha, aur eski speed 54 Mbps thi, aur ye kaphi costally tha, esliye iska alag alag Version prakashit hua tha, jiske naam se 802.11 ise start ho chuki hia WiFi technology ki ye Version ki caste low thi au rese Network ki Range bhi bahut jyada thi.

802.11a ye bahut kam time ke andar hi famous ho chukka tha, ye ek tarah se Wireless Technology ki bad aa gayi thi kabhi tezi se esne Hardware Market me apna rutaba kayam kar liya tha, range aur Compatibility ke karan kabhi famouos tha.

Ek time aisa aya ki 6 Company ne mil ke Wireless Ethernet Compatibility Alliance or WECA ka gatan kiya gaya tha, jiske jariye ye test kiya jata tha, WiFi Copitability hai,
2002 me unhone ne WiFi aur ek work HiFi bhi liya gaya tha jiske naam kuch sal me ise Wi-Fi Alliance se jana jane laga, ye tha WiFi ka History tha.
