Wi-Fi wakhala ngati njira yodziwika kwambiri yopanda waya opanda pake ya m'zaka za zana la 21. Ngakhale ma protocol ena opanda waya akuyenda bwino m'madera ena, matepi amtundu wa Wi-Fi amachititsa ma intaneti ambiri, malonda ambiri a m'madera am'deralo ndi makanema a anthu ambiri .
Anthu ena amalakwitsa mauthenga osiyanasiyana opanda waya monga "Wi-Fi" pamene kwenikweni Wi-Fi ndi imodzi mwa matekinoloji opanda waya. Onani - Zotsogoleredwa ndi Zida Zopanda Utumiki .
Mbiri ndi Mitundu ya Wi-Fi
M'zaka za m'ma 1980, teknoloji yopangidwa ndi ma CDs yotchedwa WaveLAN inakhazikitsidwa ndikuyanjanitsidwa ndi gulu la Institute of Electrical and Electronics Engineers (IEEE) lomwe likuyang'anira njira zogwirira ntchito, zomwe zimadziwika kuti komiti 802. Njirayi inakonzedwa m'ma 1990 mpaka komitiyo inasindikizidwa muyezo wa 802.11 mu 1997.
Fomu yoyamba ya Wi-Fi kuyambira m'chaka cha 1997 idalumikizana ndi 2 Mbps okha. Njira yamakonoyi sinadziwike kuti "Wi-Fi" kuyambira pachiyambi; mawu amenewo anapangidwa zaka zingapo chabe pamene kutchuka kwake kunakula. Gulu la magulu a mafakitale apitirizabe kusintha mkhalidwe kuyambira pamenepo, kupanga banja latsopano la ma-Wi-Fi omwe amatchedwa 802.11b, 802.11g, 802.11n, 802.11ac, ndi zina zotero. Zonsezi zimayankhulana wina ndi mnzake, ngakhale kuti mawonekedwe atsopano amapereka machitidwe abwino ndi zina.

Hotspots ndi mtundu wa njira zowonongeka zogwirira ntchito zomwe zimapangidwira anthu pa Intaneti. Malo ambiri ogwiritsira ntchito malo ogwiritsira ntchito pulogalamu zamapulogalamu apadera kuti asamalire kusungira kwa osuta ndi kuchepetsa kuchepa kwa intaneti mogwirizana.

Wi-Fi ili ndi protocol yolumikizana ndi deta yomwe imayendera pazilumikizidwe zosiyanasiyana (PHY) zam'tsogolo. Dongosolo la deta likuthandizira pulogalamu yapadera ya Media Access Control (MAC) yomwe imagwiritsa ntchito njira zopewera kusamvana (zomwe zimatchedwa Carrier Sense Multiple Access ndi Kupewa Kugonana kapena CSMA / CA kuthandiza kuthandizira makasitomala ambiri pa intaneti yolankhulana kamodzi
Wi-Fi imathandizira lingaliro la njira zofanana ndi za televizioni. Msewu uliwonse wa Wi-Fi umagwiritsa ntchito maulendo angapo pafupipafupi m'magulu akuluakulu (2.4 GHz kapena 5 GHz). Izi zimathandiza kuti malo amtunduwu aziyankhulana popanda kusokonezana.
