WIFI
Sab Se Pehlay To Main Ap Ko Yeh Batata Chalun Ke Wi-Fi hai kiya, Yeh Aik Wireless Local Area Network, Is network ki aik range hoti hai. Is range ke ander users is network se wirelessly connect ho kr internet use kr saktein.
Jo users is network se connect hona chahtay hoan un ke pass aesi device honi chahiye jis main WiFi Enabled ho, Yeh devices ap ki Mobile Phones bhi ho saktein hai, Loptops bhi even Mp3 Player bhoi Jab user apnay aesay device ki WiFi enable karta hai to wo device WiFi Networks scan kartein hain aur us ke baad WiFi network ki list de detin hain, sath main yeh bhi batatein hain ke in ki signal strength kiya hai. Phir user jab ksi network ko select krta hai to Ap ki device WIFI network se connect krnay ki kooshs krti hai jis per mostly WEP key( Wireless Equivalent Privacy) mangi gati hai. Agr user WEP key correct de de to ap ki connectivity WIreless LAN se ho gati hai. Ab ap internet use kr saktay hain.
Aese locations jis main ap internet use kr saktay ho Wirless Lan se connect ho kr un ko HOTSPOT kehtay hain. Mostly HOTSPOTS universities, Airports wagera hotay hain. Ap ne simple kia karna hai aese HOTSPOT per jana hai aur WIFI network se connect hona hai agr ap ko WEP key pata hai to.
Ab WIFI Connectivity aur coverage ke peechay antennas hotay hain. e.g meri university main computer lab walaon ne antenna lagaya hua jai jis ki waja se main apni unversity ke ander ander laptop ke zarye WIFI Network se connect ho kr internet use krskta hun!
WIFI network laganay se pehlay bohat sarey parameters hotay hain, kiyu ke jahan bhi Wireless Network main security ko bohat bohat properly maintain krna hota hai!

3G
3G ko 3rd Generation bhi bola gata hai... jis tarhan hum loogo ne processor ki generation banaye hui hain na Pentium-1, Pentium-2, Pentium-3, Pentium-4 isi tarhan hum loog wireless technology ko bhi mukhlatif generations hotein hain 1G 1st Generation, 2G 2nd Generation, 3G 3rd Generation, 4G 4th Generation.... In main sab se latest jo hai wo 4G hai jo ke officially launch honi hai..
Ok Har Generation main Technologies hotein hain..
.1G main hamarey pass analog technologies thein
.2G main hamarey pass digital technologies aa gaein, GSM bhi 2G ke ander ati hai
.3G main kuch aese aur technologies laein gein jis main hmaraey pass bandwidth zeyada thi, ap video calls kr saktay thea, example technology UMTS hai jis main ap voice aur data dono aik sath use kr saktay ho
.4G main jo concept deya geya hai wo ALL-IP ka hai.. is main zeyada acha data rate milta hai, video calling, IP TV, MMS ap use kr saktay ho "Anytime", "Anywhere"....
To 3G kiya hai basically 3rd Generation aur is main aik acha data rate acheive ap kr saktay ho.. main aik example ke sath ap ko samjana chahun ga ap ke pass mobile hai ap us main net use krtay ho downloading kr rahay ho aur downloading krtay wqt ap ke pass call aa jaye to ap ka internet thori deer ke leye hold per chala gata hai aur ap ki downloading pause ho gati hai jb ap call end krtay ho phir wo resume ho gati hai..... yani ke ap downloading aur phone calls aik wqt sath main nahe kr saktay ksi ko hold per jana ho ga... agr 3G technology UMTS use kro to ap dono service Data & Voice ko sath use kr saktay ho... koe bhi service hold per nahe jaye gi... Aur 3G technologies ap ko acha Data Rate provide krtein hain
EDGE
Edge bhi aik technology jo ke GPRS ki enchanced form hai... har wo network jo GPRS per chal raha hai wo EDGE per shift ho sakta hai bus thori si modifications required hotein hain network main.. ab Edge ka faida kiya hai.. Edge GPRS se kafi acha data rate provide krta hai.. !!
