3G VS WI-FI
ABSTRACT
3G is the third generation mobile technology for mobile service operators to offer integrated data and voice service over mobile network. It is an International Telecommunication Union (ITU) standard under the International Mobile Telecommunication Mobile Programmers, IMT-2000. This is the technology of choice for upgrading existing mobile telephone service to expand capacity and add enhanced services. 3G offers a vertically integrated up-down service-provider approach to delivering wireless internet access and operate using a license spectrum with a data rate of from 384 Kbps upto2Mbps.Wi-Fi is the popular name for the Wireless Ethernet 802.11b Standard for WLANs. It is one of the successions of Ethernet standard approved by IEEE for to support higher capacity LANs. Wi-Fi LANsoperate using unlicensed spectrum in the 2.4GHz.band. Typically the WLANs are implemented as part of a private network. The base station equipment is owned & operated by the end user. WLANsare principally focused on supporting data communication. However it is possible to support voice telephony service over WLANs. Wi-Fi access can emerge in a decentralized, bottom up fashion. We compare and contrast 3G and Wi-Fi for delivering broadband Wireless Internet Accessservices.The former, 3G refers to the technology that offer integrated data and voice service over mobile networks. The later Wi-Fi refers to Wireless Ethernet Technology which supports wirelessLANs. Although the two technologies reflect fundamentally different service, industry and architectural design goals, origins and philosophies, each has recently attracted a lot of attention as candidate providing broadband Wireless access to Internet.
